On the prince of darkness: the Watchtower society's commentary.

 SATAN

[Resister].

In many places in the Hebrew Scriptures, the word sa·tanʹ appears without the definite article. Used in this way, it applies in its first appearance to the angel that stood in the road to resist Balaam as he set out with the objective of cursing the Israelites. (Nu 22:22, 32) In other instances it refers to individuals as resisters of other men. (1Sa 29:4; 2Sa 19:21, 22; 1Ki 5:4; 11:14, 23, 25) But it is used with the definite article ha to refer to Satan the Devil, the chief Adversary of God. (Job 1:6, ftn; 2:1-7; Zec 3:1, 2) In the Greek Scriptures the word sa·ta·nasʹ applies to Satan the Devil in nearly all of its occurrences and is usually accompanied by the definite article ho.

Origin. The Scriptures indicate that the creature known as Satan did not always have that name. Rather, this descriptive name was given to him because of his taking a course of opposition and resistance to God. The name he had before this is not given. God is the only Creator, and ‘his activity is perfect,’ with no injustice or unrighteousness. (De 32:4) Therefore, the one becoming Satan was, when created, a perfect, righteous creature of God. He is a spirit person, for he appeared in heaven in the presence of God. (Job chaps 1, 2; Re 12:9) Jesus Christ said of him: “That one was a manslayer when he began, and he did not stand fast in the truth, because truth is not in him.” (Joh 8:44; 1Jo 3:8) Jesus here shows that Satan was once in the truth, but forsook it. Beginning with his first overt act in turning Adam and Eve away from God, he was a manslayer, for he thereby brought about the death of Adam and Eve, which, in turn, brought sin and death to their offspring. (Ro 5:12) Throughout the Scriptures the qualities and actions attributed to him could be attributed only to a person, not to an abstract principle of evil. It is clear that the Jews, and Jesus and his disciples, knew that Satan existed as a person.

So, from a righteous, perfect start, this spirit person deviated into sin and degradation. The process bringing this about is described by James when he writes: “Each one is tried by being drawn out and enticed by his own desire. Then the desire, when it has become fertile, gives birth to sin; in turn, sin, when it has been accomplished, brings forth death.” (Jas 1:14, 15) In the course that Satan took, there seems to be, in some respects, a parallel with that of the king of Tyre as described in Ezekiel 28:11-19.​—See PERFECTION (The first sinner and the king of Tyre).

The Scriptural account, therefore, makes it plain that it was Satan who spoke through the medium of a serpent, seducing Eve into disobedience to God’s command. In turn, Eve induced Adam to take the same rebellious course. (Ge 3:1-7; 2Co 11:3) As a consequence of Satan’s use of the serpent, the Bible gives Satan the title “Serpent,” which came to signify “deceiver”; he also became 
“the Tempter” (Mt 4:3) and a liar, “the father of the lie.”​—Joh 8:44; Re 12:9.

Issue of Sovereignty Raised. When Satan approached Eve (through the speech of the serpent), he actually challenged the rightfulness and righteousness of Jehovah’s sovereignty. He intimated that God was unrightfully withholding something from the woman; he also declared that God was a liar in saying that she would die if she ate the forbidden fruit. Additionally, Satan made her believe she would be free and independent of God, becoming like God. By this means this wicked spirit creature raised himself higher than God in Eve’s eyes, and Satan became her god, even though Eve, at the time, apparently did not know the identity of the one misleading her. By his action he brought man and woman under his leadership and control, standing up as a rival god in opposition to Jehovah.​—Ge 3:1-7.

The Bible, in lifting the veil to give a glimpse into heavenly affairs, reveals that Satan later as a rival god appeared before Jehovah in heaven, challenging Jehovah to His face, saying that he could turn God’s servant Job, and by implication any servant of God, away from Him. He charged God, in effect, with unrighteously giving Job everything, along with full protection, so that he, Satan, could not test Job and show what was really in his heart, which, Satan intimated, was bad. He implied that Job served God primarily for selfish considerations. Satan made this point of his argument clear when he said: “Skin in behalf of skin, and everything that a man has he will give in behalf of his soul. For a change, thrust out your hand, please, and touch as far as his bone and his flesh and see whether he will not curse you to your very face.”​—Job 1:6-12; 2:1-7; see SOVEREIGNTY.

In this special case, Jehovah allowed Satan to bring calamity upon Job by not interfering when Satan brought about a raid from Sabean marauders as well as destruction of flocks and shepherds by what Job’s messenger called “the very fire of God” from the heavens; whether this was lightning or other fire is not stated. Satan also brought a raid by three bands of Chaldeans, as well as a windstorm. These things caused the death of all of Job’s children and destroyed his property. Finally, Satan inflicted a loathsome disease upon Job himself.​—Job 1:13-19; 2:7, 8.

These things reveal the might and power of the spirit creature Satan, as well as his vicious, murderous attitude.

It is important to note, however, that Satan recognized his impotence in the face of God’s express command, for he did not challenge God’s power and authority when God restricted him from taking Job’s life.​—Job 2:6.

Continued Opposition to God. By his challenge of God and his charging God’s servants with lack of integrity, Satan lived up to his title “Devil,” meaning “Slanderer,” which title he deserved for having slandered Jehovah God in the garden of Eden.

Joined by other wicked demons. Before the Flood of Noah’s day, it appears that other angels of God left their proper habitation in the heavens, as well as their assigned positions there. Materializing human bodies, they came to dwell on earth, marrying women and producing offspring called Nephilim. (Ge 6:1-4; 1Pe 3:19, 20; 2Pe 2:4; Jude 6; see NEPHILIMSON[S] OF GOD.) These angels, having left God’s service, came under the control of Satan. Hence Satan is called “the ruler of the demons.” In one instance, when Jesus expelled demons from a man, the Pharisees accused him of doing so by the power of “Beelzebub, the ruler of the demons.” That they had reference to Satan is shown by Jesus’ answer: “If Satan expels Satan, he has become divided against himself.”​—Mt 12:22-27.

The apostle Paul associates Satan with “the wicked spirit forces in the heavenly places,” and he speaks of them as “the world rulers of this darkness.” (Eph 6:11, 12) As a governing force in the invisible realm immediately about the earth, Satan is “the ruler of the authority of the air.” (Eph 2:2) In Revelation he is shown to be the one “misleading the entire inhabited earth.” (Re 12:9) The apostle John said that “the whole world is lying in the power of the wicked one.” (1Jo 5:19) He is therefore “the ruler of this world.” (Joh 12:31) That is why James wrote that “the friendship with the world is enmity with God.”​—Jas 4:4.

His Fight to Destroy the “Seed.” Satan made early efforts to block the promise of the “seed” to come through Abraham. (Ge 12:7) He evidently tried to get Sarah contaminated so that she would be unfit to bear the seed; but God protected her. (Ge 20:1-18) He did everything possible to destroy the ones whom God chose as Abraham’s seed, the nation of Israel, by inducing them to sin and by bringing other nations against them, as Bible history shows throughout. A high point in Satan’s ambitious attempts in his fight against God, and what appeared to Satan to be success, was reached when the king of the Third World Power of Bible history, Babylon, took Jerusalem, overturning the rulership of King Zedekiah of 
the line of David, and destroyed the temple of Jehovah, desolating Jerusalem and Judah.​—Eze 21:25-27.

As an instrument of Satan, the ruling dynasty of Babylon, initially headed by Nebuchadnezzar, held Israel in exile for 68 years, until Babylon’s overthrow. Babylon had no intention of ever releasing its captives and so reflected Satan’s own boastful, ambitious attempts as a rival god opposed to the Universal Sovereign Jehovah. The Babylonian kings, worshiping their idol god Marduk, the goddess Ishtar, and a host of others, were actually worshipers of the demons and, as part of the world alienated from Jehovah, were under Satan’s domination.​—Ps 96:5; 1Co 10:20; Eph 2:12; Col 1:21.

Satan filled the king of Babylon with the ambition to have complete domination over the earth, even over “Jehovah’s throne” (1Ch 29:23) and “the stars of God,” the kings of the line of David sitting on the throne at Mount Moriah (by extension, Zion). This “king,” that is, the dynasty of Babylon, ‘lifted himself up’ in his own heart and was in his own eyes and in the eyes of his admirers a “shining one,” a “son of the dawn.” (In some translations the Latin Vulgate term “Lucifer” is retained. It is, however, merely the translation of the Hebrew word heh·lelʹ, “shining one.” Heh·lelʹ is not a name or a title but, rather, a term describing the boastful position taken by Babylon’s dynasty of kings of the line of Nebuchadnezzar.) (Isa 14:4-21) Since Babylon was a tool of Satan, its “king” reflected Satan’s own ambitious desire. Again, Jehovah came to the salvation of his people by restoring them to their land, until the real Seed of promise should come.​—Ezr 1:1-6.

Efforts to cause Jesus to stumble. Satan, no doubt identifying Jesus as the Son of God and the one who was prophesied to bruise him in the head (Ge 3:15), did everything he could to destroy Jesus. But, when announcing the conception of Jesus to Mary, the angel Gabriel told her: “Holy spirit will come upon you, and power of the Most High will overshadow you. For that reason also what is born will be called holy, God’s Son.” (Lu 1:35) Jehovah safeguarded his Son. The efforts to destroy Jesus when an infant were unsuccessful. (Mt 2:1-15) God continued to protect Jesus during his youth. After his baptism, Satan approached Jesus in the wilderness with three different strong temptations, thoroughly testing him on the issue of devotion to Jehovah. In one of his appeals Satan showed Jesus all the kingdoms of the world, claiming them to be his own. Jesus did not contradict this claim. Nonetheless, Jesus refused to contemplate even for the briefest instant of time any “shortcut” to kingship, nor did he consider for an instant the doing of anything merely to please himself. His immediate reply to Satan was, “Go away, Satan! For it is written, ‘It is Jehovah your God you must worship, and it is to him alone you must render sacred service.’” At this, “the Devil . . . retired from him until another convenient time.” (Mt 4:1-11; Lu 4:13) This illustrates the truth of James’ words later written: “Oppose the Devil, and he will flee from you.”​—Jas 4:7.

Jesus was ever alert to the danger of Satan’s machinations and to the fact that Satan desired to cause his destruction by getting him to entertain a thought contrary to Jehovah’s will. This was demonstrated when Peter, on one occasion, though with good intentions, was actually throwing temptation in his way. Jesus had spoken of the suffering and death he was to undergo. “At this Peter took him aside and commenced rebuking him, saying: ‘Be kind to yourself, Lord; you will not have this destiny at all.’ But, turning his back, he said to Peter: ‘Get behind me, Satan! You are a stumbling block to me, because you think, not God’s thoughts, but those of men.’”​—Mt 16:21-23.

Throughout Jesus’ ministry he was in danger; Satan used human agents to oppose Jesus, trying either to cause him to stumble or to kill him. At one time the people were about to seize Jesus to make him king. But he would not consider such a thing; he would accept kingship only in God’s time and way. (Joh 6:15) On another occasion those of his own hometown attempted to kill him. (Lu 4:22-30) He was constantly harassed by those whom Satan used to try to trap him. (Mt 22:15) But in all of Satan’s efforts, he failed to cause Jesus to sin in the slightest thought or deed. Satan was thoroughly proved to be a liar, and he failed in his challenge of God’s sovereignty and the integrity of God’s servants. As Jesus said, shortly before his death: “Now there is a judging of this world; now the ruler of this world will be cast out”​—completely discredited. (Joh 12:31) Satan had a grip on all mankind through sin. But, knowing that Satan would soon bring about his death, Jesus, after celebrating his last Passover with his disciples, could say: “The ruler of the world is coming. And he has no hold on me.”​Joh 14:30.

A few hours later, Satan succeeded in having Jesus put to death, first getting control of one of Jesus’ apostles, then using the Jewish leaders and the Roman World Power to execute Jesus in a painful and ignominious manner. (Lu 22:3; Joh 13:26, 
27; chaps 18, 19) Here Satan acted as “the one having the means to cause death, that is, the Devil.” (Heb 2:14; Lu 22:53) But in this Satan failed to promote his cause; he only unwillingly fulfilled prophecy, which required that Jesus die as a sacrifice. The death of Jesus in blamelessness provided the ransom price for humankind, and by his death (and subsequent resurrection by God) Jesus could now help sinful humankind to escape from the grip of Satan, for, as it is written, Jesus became blood and flesh “that through his death he might bring to nothing the one having the means to cause death, that is, the Devil; and that he might emancipate all those who for fear of death were subject to slavery all through their lives.”​—Heb 2:14, 15.

Continues to fight Christians. After Jesus’ death and resurrection, Satan continued to wage a bitter fight against Christ’s followers. The accounts in the book of Acts and in the letters of the Christian Greek Scriptures furnish numerous proofs of this. Paul said that he had been given “a thorn in the flesh, an angel of Satan, to keep slapping” him. (2Co 12:7) And as in the case with Eve, Satan disguised his real nature and purposes by “transforming himself into an angel of light,” and he had agents, ministers who “also keep transforming themselves into ministers of righteousness.” (2Co 11:14, 15) Examples of these were the false apostles who fought against Paul (2Co 11:13) and those in Smyrna ‘who said they themselves were Jews, and yet they were not but were a synagogue of Satan.’ (Re 2:9) Satan never ceased in making accusations “day and night” against Christians, challenging their integrity, as he did Job’s. (Re 12:10; Lu 22:31) But Christians have “a helper with the Father, Jesus Christ, a righteous one,” who appears before the person of God in their behalf.​—1Jo 2:1.

His Abyssing and Final Destruction. At the time of Satan’s act in causing Eve and then Adam to rebel against God, God said to the serpent (actually speaking to Satan, since a mere beast could not understand the issues involved): “Dust is what you will eat all the days of your life. And I shall put enmity between you and the woman and between your seed and her seed. He will bruise you in the head and you will bruise him in the heel.” (Ge 3:14, 15) Here God made it known that Satan, cast outside God’s holy organization, would have no life-sustaining hope but would ‘eat dust,’ as it were, until he died. The “seed” eventually was to bruise him in the head, which would signify a death wound. When Christ was on earth, the demons identified him as the One who was to hurl them into the “abyss,” evidently a condition of restraint that in the parallel account is spoken of as “torment.”​—Mt 8:29; Lu 8:30, 31; see TORMENT.

In the book of Revelation, we find described the last days of Satan and his end. Revelation reports that at the time of Christ’s taking Kingdom power, Satan is hurled down out of heaven to the earth, no longer having access to the heavens, as he did in the days of Job and for centuries thereafter. (Re 12:7-12) After this defeat Satan has only a “short period of time,” during which he makes war with “the remaining ones of [the woman’s] seed, who observe the commandments of God and have the work of bearing witness to Jesus.” In his efforts to devour the remaining ones of the woman’s seed, he is called “the dragon,” a swallower or crusher. (Re 12:16, 17; compare Jer 51:34, where Jeremiah speaks for Jerusalem and Judah, saying: “Nebuchadrezzar the king of Babylon . . . has swallowed me down like a big snake [or, “a dragon,” ftn].”) In the earlier description of his fight against the woman and his efforts to devour her man child, he is pictured as “a great fiery-colored dragon.”​—Re 12:3.

Revelation’s 20th chapter describes Satan’s being bound and abyssed for a thousand years, at the hands of a great angel​—doubtless Jesus Christ, who has the key of the abyss and who is the “seed” to bruise Satan’s head.​—Compare Re 1:18; see ABYSS.

Satan’s final effort culminates in permanent defeat. The prophecy says that he is to be let loose for “a little while” as soon as Christ’s Thousand Year Reign is ended and that he will lead rebellious persons in another attack upon God’s sovereignty; but he is hurled (along with his demons) into the lake of fire and sulfur, everlasting destruction.​—Re 20:1-3, 7-10; compare Mt 25:41; see LAKE OF FIRE.

What is meant by ‘handing a person over to Satan for destruction of the flesh’?

In instructing the congregation at Corinth as to the action to take toward a member of the congregation who had wickedly been committing incest with the wife of his father, the apostle Paul wrote: “Hand such a man over to Satan for the destruction of the flesh.” (1Co 5:5) This was a command to expel the man from the congregation, cutting off all fellowship with him. (1Co 5:13) Turning 
him over to Satan would put him out of the congregation and into the world over which Satan is the god and ruler. Like “a little leaven” in “the whole lump” of dough, this man was “the flesh,” or fleshly element inside the congregation; and by removing this incestuous man, the spiritually minded congregation would destroy “the flesh” from the midst of it. (1Co 5:6, 7) Similarly, Paul handed Hymenaeus and Alexander over to Satan, because they had thrust aside faith and a good conscience and had experienced shipwreck concerning their faith.​—1Ti 1:20.

Later, the incestuous man in Corinth apparently repented from his wrongdoing and cleaned up, prompting the apostle Paul to recommend his being received back into the congregation. In exhorting them to forgiveness, he gave as one of the reasons, “that we may not be overreached by Satan, for we are not ignorant of his designs.” (2Co 2:11) In the first instance, Satan had brought the congregation into a bad condition in which they had to be reproved by the apostle, for they were too lenient, in fact, were letting the wicked man carry on his practice without regard for the reproach it brought, being “puffed up” in allowing it. (1Co 5:2) But on the other hand, if they now swung to the other extreme and refused forgiveness to the repentant one, Satan would be overreaching them in another direction, namely, that he could take advantage of their becoming hard and unforgiving. Through God’s Word, Christians are enlightened to realize Satan’s existence, his power, his designs and purposes, and his manner of operation, so that they can fight this spiritual foe with the spiritual weapons God provides.​—Eph 6:13-17.

Hinduism: a brief history.

 Hinduism is an Indian religion and dharma, or way of life. It is the world's third-largest religion, with over 1.2 billion followers, or 15–16% of the global population, known as Hindus. The word Hindu is an exonym, and while Hinduism has been called the oldest religion in the world, many practitioners refer to their religion as Sanātana Dharma (Sanskrit: सनातनधर्म:, lit. ''the Eternal way''), which refers to the idea that its origins lie beyond human history, as revealed in the Hindu texts. Another, though less fitting, self-designation is Vaidika dharma, the 'dharma related to the Vedas.'


Hinduism is a diverse system of thought marked by a range of philosophies and shared concepts, ritualscosmological systems, pilgrimage sites and shared textual sources that discuss theology, metaphysicsmythology, Vedic yajnayogaagamic rituals, and temple building, among other topics. Prominent themes in Hindu beliefs include the four Puruṣārthas, the proper goals or aims of human life; namely, dharma (ethics/duties), artha (prosperity/work), kama (desires/passions) and moksha (liberation/freedom from the cycle of death and rebirth/salvation), as well as karma (action, intent and consequences) and saṃsāra (cycle of death and rebirth). Hinduism prescribes the eternal duties, such as honesty, refraining from injuring living beings (Ahiṃsā), patience, forbearance, self-restraint, virtue, and compassion, among others. Hindu practices include rituals such as puja (worship) and recitations, japa, meditation (dhyāna), family-oriented rites of passage, annual festivals, and occasional pilgrimages. Along with the practice of various yogas, some Hindus leave their social world and material possessions and engage in lifelong Sannyasa (monasticism) in order to achieve Moksha.

Hindu texts are classified into Śruti ("heard") and Smṛti ("remembered"), the major scriptures of which are the Vedas, the Upanishads, the Purānas, the Mahābhārata, the Rāmāyana, and the Āgamas. There are six āstika schools of Hindu philosophy, who recognise the authority of the Vedas, namely SānkhyaYogaNyāyaVaisheshikaMimāmsā and Vedānta. While the Puranic chronology presents a genealogy of thousands of years, starting with the Vedic rishis, scholars regard Hinduism as a fusion or synthesis of Brahmanical orthopraxy with various Indian cultures, having diverse roots and no specific founder. This Hindu synthesis emerged after the Vedic period, between c. 500 –200 BCE and c. 300 CE, in the period of the Second Urbanisation and the early classical period of Hinduism, when the Epics and the first Purānas were composed. It flourished in the medieval period, with the decline of Buddhism in India.

Currently, the four largest denominations of Hinduism are VaishnavismShaivismShaktism and Smartism. Sources of authority and eternal truths in the Hindu texts an important role, but there is also a strong Hindu tradition of questioning authority in order to deepen the understanding of these truths and to further develop the tradition. Hinduism is the most widely professed faith in IndiaNepal and Mauritius. Significant numbers of Hindu communities are found in Southeast Asia including in BaliIndonesia, the CaribbeanNorth AmericaEuropeOceaniaAfrica, and other regions. Hinduism is the second fastest-growing religion in the world, after Islam with a growth of 17%.

Druzism: a brief history.

Druze are members of an Arabic-speaking esoteric ethnoreligious group originating in Western Asia. They practice Druzism, an Abrahamicmonotheisticsyncretic, and ethnic religion based on the teachings of Hamza ibn Ali ibn Ahmad and the sixth Fatimid caliphal-Hakim bi-Amr Allah, and Ancient Greek philosophers such as PlatoAristotlePythagoras, and Zeno of Citium. Adherents of the Druze religion are called The People of Monotheism (Al-Muwaḥḥidūn).

The Epistles of Wisdom is the foundational and central text of the Druze faith. The Druze faith incorporates elements of Isma'ilismGnosticismChristianityZoroastrianismBuddhismHinduismNeoplatonismPythagoreanism, and other philosophies and beliefs, creating a distinct and secretive theology based on an esoteric interpretation of scripture, which emphasizes the role of the mind and truthfulness. Druze believe in theophany and reincarnation. Druze believe that at the end of the cycle of rebirth, which is achieved through successive reincarnations, the soul is united with the Cosmic Mind (al-ʻaql al-kullī).

Even though the faith originally developed out of Isma'ilism, Druze do not identify as Muslims. The Druze faith is one of the major religious groups in the Levant, with between 800,000 and a million adherents. They are found primarily in LebanonSyria, and Israel, with small communities in Jordan. They make up 5.5% of the population of Lebanon, 3% of Syria and 1.6% of Israel. The oldest and most densely-populated Druze communities exist in Mount Lebanon and in the south of Syria around Jabal al-Druze (literally the "Mountain of the Druze").

The Druze community played a critically important role in shaping the history of the Levant, where it continues to play a significant political role. As a religious minority in every country in which they are found, they have frequently experienced persecution by different Muslim regimes, including contemporary Islamic extremism. 

Stephen Hawking: a brief history.

Stephen William Hawking CH CBE FRS FRSA (8 January 1942 – 14 March 2018) was an English theoretical physicistcosmologist, and author who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge at the time of his death. He was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009.

Hawking was born in Oxford into a family of doctors. He began his university education at University College, Oxford, in October 1959 at the age of 17, where he received a first-class BA degree in physics. He began his graduate work at Trinity Hall, Cambridge, in October 1962, where he obtained his PhD degree in applied mathematics and theoretical physics, specialising in general relativity and cosmology in March 1966. In 1963, Hawking was diagnosed with an early-onset slow-progressing form of motor neurone disease that gradually paralysed him over the decades. After the loss of his speech, he communicated through a speech-generating device initially through use of a handheld switch, and eventually by using a single cheek muscle.

Hawking's scientific works included a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction that black holes emit radiation, often called Hawking radiation. Initially, Hawking radiation was controversial. By the late 1970s and following the publication of further research, the discovery was widely accepted as a significant breakthrough in theoretical physics. Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He was a vigorous supporter of the many-worlds interpretation of quantum mechanics.

Hawking achieved commercial success with several works of popular science in which he discussed his theories and cosmology in general. His book A Brief History of Time appeared on the Sunday Times bestseller list for a record-breaking 237 weeks. Hawking was a Fellow of the Royal Society, a lifetime member of the Pontifical Academy of Sciences, and a recipient of the Presidential Medal of Freedom, the highest civilian award in the United States. In 2002, Hawking was ranked number 25 in the BBC's poll of the 100 Greatest Britons. He died on 14 March 2018 at the age of 76, after living with motor neurone disease for more than 50 years.

The Big bang: a brief history.

 The Big Bang theory is the prevailing cosmological model explaining the existence of the observable universe from the earliest known periods through its subsequent large-scale evolution. The model describes how the universe expanded from an initial state of high density and temperature, and offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure.


Crucially, the theory is compatible with Hubble–Lemaître law—the observation that the farther away a galaxy is, the faster it is moving away from Earth. Extrapolating this cosmic expansion backwards in time using the known laws of physics, the theory describes an increasingly concentrated cosmos preceded by a singularity in which space and time lose meaning (typically named "the Big Bang singularity"). Detailed measurements of the expansion rate of the universe place the Big Bang singularity at around 13.8 billion years ago, which is thus considered the age of the universe.

After its initial expansion, an event that is by itself often called "the Big Bang", the universe cooled sufficiently to allow the formation of subatomic particles, and later atoms. Giant clouds of these primordial elements—mostly hydrogen, with some helium and lithium—later coalesced through gravity, forming early stars and galaxies, the descendants of which are visible today. Besides these primordial building materials, astronomers observe the gravitational effects of an unknown dark matter surrounding galaxies. Most of the gravitational potential in the universe seems to be in this form, and the Big Bang theory and various observations indicate that this excess gravitational potential is not created by baryonic matter, such as normal atoms. Measurements of the redshifts of supernovae indicate that the expansion of the universe is accelerating, an observation attributed to dark energy's existence.

Georges Lemaître first noted in 1927 that an expanding universe could be traced back in time to an originating single point, which he called the "primeval atom". Edwin Hubble confirmed through analysis of galactic redshifts in 1929 that galaxies are indeed drifting apart; this is important observational evidence for an expanding universe. For several decades, the scientific community was divided between supporters of the Big Bang and the rival steady-state model which both offered explanations for the observed expansion, but the steady-state model stipulated an eternal universe in contrast to the Big Bang's finite age. In 1964, the CMB was discovered, which convinced many cosmologists that the steady-state theory was falsified, since, unlike the steady-state theory, the hot Big Bang predicted a uniform background radiation throughout the universe caused by the high temperatures and densities in the distant past. A wide range of empirical evidence strongly favors the Big Bang, which is now essentially universally accepted.

Primeval tech continues to deconstruct Darwininism.

 

Tricks of the Cell Trade

Evolution News DiscoveryCSC

Both cables on a suspension bridge snap. It’s going to collapse. If repairmen cannot mend the cables extremely rapidly, the bridge is doomed, and all the cars on it will dump into the water. Time is of the essence. The task looks hopeless. What to do?

Homologous Recombination

Cells face that kind of challenge every day, but they are well equipped to handle it. When both DNA strands break (the “double-stranded break” crisis, or DSB), a cell can die. Molecular machines fly into action as the strands flail about, threatening genomic catastrophe. The repair crew has an additional problem: unlike the bridge cable, the DNA strand is made up of a sequence of code that needs to match what was there before the DSB. In a process called homologous recombination, the machinery searches for a template to rebuild the broken sequence. Researchers at Uppsala University know that this process is mostly “well described in the literature.”

However, the description usually disregards the daunting task of finding the matching template among all the other genome sequences. The chromosome is a complex structure with several million base pairs of genetic code and it is quite clear that simple diffusion in 3D would not be sufficiently fast by a long shot. But then, how is it done? This has been the mystery of homologous recombination for 50 years. From previous studies, it is clear that the molecule RecA is involved and important in the search process, but, up until now, this has been the limit of our understanding of this process. [Emphasis added.]

Even a simple bacterium knows a trick to make the search easier. It reduces the search from a 3D problem to a 2D problem. With that shortcut, the cell reduces the time to repair down to 15 minutes on average. The Uppsala group, using CRISPR and fluorescent tags, watched the RecA proteins in real time. They published their findings in Nature.

“We can see the formation of a thin, flexible structure that protrudes from the break site just after the DNA damage. Since the DNA ends are incorporated into this fiber, it is sufficient that any part of the filament findsthe precious template and thus the search is theoretically reduced from three to two dimensions. Our model suggests that this is the key to fast and successful homology repair,” says Arvid Gynnå, who has worked on the project throughout his PhD studies.

Earth’s Electrical Grid

The world beneath our feet is electrically wired. That’s the surprising announcement from Yale University about bacteria that live in soil and under the seafloor. 

A hair-like protein hidden inside bacteria serves as a sort of on-off switch for nature’s “electric grid,” a global web of bacteria-generated nanowires that permeates all oxygen-less soil and deep ocean beds, Yale researchers report in the journal Nature.

“The ground beneath our feet, the entire globe, is electrically wired,” said Nikhil Malvankar, assistant professor of molecular biophysics and biochemistry at the Microbial Science Institute at Yale’s West Campus and senior author of the paper. “These previously hidden bacterial hairs are the molecular switch controlling the release of nanowires that make up nature’s electrical grid.”

The Yale team found more about the “pili” which were thought to be made of a surface proteins by that name. Their findings, also published in Naturewe learn, call into question “thousands of publications about pili.” Pili are not the nanowires; they are machines that pump the nanowires out of the cell. Bacteria use these electrical conduits for respiration. Lacking access to oxygen (the primary electron receptor of oxygen-breathing organisms like humans), the bacteria use nanowires like snorkels to “breathe minerals” below the surface. The nanowires push excess electrons up and out of sediments.

A short animation shows how the pili work. They extend and retract repeatedly, pushing the nanowires out a bit at a time. Engineers might watch this trick to solve the problem of how to push a rope! The nanowires from bacteria link up and can extend a considerable distance on a bacterial scale. Because they conduct electrons, are ubiquitous around the earth, and provide global recycling services (see here), the nanowires justify the description of “nature’s electrical grid” under our feet. For fun, consider a new kind of silicon-impregnated wood flooring that generates electricity. Just walking on the floor, invented in Switzerland, can generate enough electricity to power a light bulb, reports Science Daily.

Tunnel Experts

A robot spacecraft, resembling an old Apollo lunar lander, touches down secretly on an enemy cargo ship. Underneath, a powerful drill breaks through the steel exterior. Material flows into the breach, melting the metal casing and building a tunnel through which the craft sends code to infect the enemy ship’s computers. Moments later, the enemy ship explodes, releasing hundreds of copies of the robot to go fight other enemy ships.

Viruses do things like that. A good one, the T7 bacteriophage, protects us from E. coli infections. Scientists in Spain, publishing in PNAS, learned more about how T7 builds its export tunnel through which it sends DNA into the harmful bacterial cell. 

Bacteriophage T7 infects Escherichia coli bacteria, and its genomic DNA traverses the bacterial cell envelope,but the precise mechanism used by the virus remains unknown. Previous studies suggested that proteins found inside the viral capsid (core proteins) disassemble and reassemble in the bacterial periplasm to form a DNA translocation channel. In this article, we have solved the structure of two different assemblies of the core proteins gp15 and gp16. These findings confirm the ability of core proteins to form tubes compatible with the periplasmic space and show the location of the transglycosylase enzyme involved in peptidoglycan degradation. Our results reveal key structural details of the assembly of the core translocation complex involved in the DNA transport through the bacterial wall.

The paper mentions an interesting fact: “Bacteriophages (phages) are viruses that infect bacteria and are considered to be the most abundant entities on Earth.” 

Windows on the Unseen

In each of these discoveries, cryo-electron microscopy opened windows to unseen realities. This revolutionary tool and other methods of super-resolution microscopy are enabling scientists to see biological wonders that have existed as far back as the first bacterial cells, but have been hidden from our eyes till now. Step by step, molecule by molecule, the evidence for intelligent design at the tiniest levels of life is coming into focus. With more academicians taking leave of Darwin, how can the scientific community deny a seat at the table to design proponents who have the necessary and sufficient causes to explain these things? 

Neil Thomas, calling the materialist paradigm a “flawed hypothesis” that is “squandering public trust,” concludes that it’s time to open the doors to alternatives:

Faced with the sheer unfeasibility of a purely natural explanation, logic leaves us with little other choice. Extending the old adage that nothing comes of nothing, it might be contended that real life, in contradistinction to the magician’s claim of a rabbit magically emerging from the hat, nothing can “magically emerge” or “naturally evolve” without a supporting agency — little though we may know of that originating agency. In default of a better explanation than that offered by the Darwinian paradigm and its various materialistic descendants and kissing cousins, however, this hypothesis surely cannot be discounted out of hand.
