Oumuamua: a brief history.

 ʻOumuamua is the first known interstellar object detected passing through the Solar System. Formally designated 1I/2017 U1, it was discovered by Robert Weryk using the Pan-STARRS telescope at Haleakalā Observatory, Hawaii, on 19 October 2017, approximately 40 days after it passed its closest point to the Sun on 9 September. When it was first observed, it was about 33 million km (21 million mi; 0.22 AU) from Earth (about 85 times as far away as the Moon), and already heading away from the Sun.

ʻOumuamua is a small object estimated to be between 100 and 1,000 metres (300 and 3,000 ft) long, with its width and thickness both estimated to range between 35 and 167 metres (115 and 548 ft). It has a red color, similar to objects in the outer Solar System. Despite its close approach to the Sun, ʻOumuamua showed no signs of having a coma, but it did exhibit non‑gravitational acceleration. Nonetheless, the object could be a remnant of a disintegrated rogue comet (or exocomet), according to astronomer Zdenek Sekanina. The object has a rotation rate similar to the average spin rate seen in Solar System asteroids, but many valid models permit it to be more elongated than all but a few other natural bodies. While an unconsolidated object (rubble pile) would require it to be of a density similar to rocky asteroids, a small amount of internal strength similar to icy comets would allow a relatively low density. ʻOumuamua's light curve, assuming little systematic error, presents its motion as "tumbling", rather than "spinning", and moving sufficiently fast relative to the Sun that it is likely of an extrasolar origin. Extrapolated and without further deceleration, ʻOumuamua's path cannot be captured into a solar orbit, so it would eventually leave the Solar System and continue into interstellar space. ʻOumuamua's planetary system of origin and the age of its excursion are unknown.

In July 2019, astronomers concluded that ʻOumuamua is most likely a natural object. A small number of astronomers suggested that ʻOumuamua could be a product of alien technology, but evidence in support of this hypothesis is weak. In March 2021, scientists presented a theory based on nitrogen ice that ʻOumuamua may be a piece of an exoplanet similar to Pluto, from beyond our solar system.

Panentheism: a brief history.

Panentheism (meaning “all-in-God”) is the belief that the divine pervades and interpenetrates every part of the universe and also extends beyond space and time. The term was coined by the German philosopher Karl Krause in 1828 to distinguish the ideas of Georg Wilhelm Friedrich Hegel (1770–1831) and Friedrich Wilhelm Joseph Schelling (1775–1854) about the relation of God and the universe from the supposed pantheism of Baruch Spinoza. Unlike pantheism, which holds that the divine and the universe are identical, panentheism maintains an ontological distinction between the divine and the non-divine and the significance of both.<

• In panentheism, God is viewed as the soul of the universe, the universal spirit present everywhere, which at the same time “transcends” all things created.
• While pantheism asserts that “all is God”, panentheism claims that God is greater than the universe. Some versions of panentheism suggest that the universe is nothing more than the manifestation of God. In addition, some forms indicate that the universe is contained within God, like in the Kabbalah concept of tzimtzum. Also much Hindu thought – and consequently Buddhist philosophy – is highly characterized by panentheism and pantheism. The basic tradition however, on which Krause’s concept was built, seems to have been Neoplatonic philosophy and its successors in Western philosophy and Orthodox theology.

Panentheism

Panentheism, literally "all-in-God-ism", "affirms that although God and the world are ontologically distinct [i.e., not the same] and God transcends the world, the world is 'in' God ontologically." ^ [1]^ This is not to be confused with pantheism, which understands God to be the world. For most panentheists, God is intimately connected to the world and yet remains greater than the world. In this view, events and changes in the universe affect and change God, and he is therefore a temporal being. As the universe grows, God learns as he increases in knowledge and being.

Panentheism has been associated with process theology and aspects of open theism, including theologians such as Paul Tillich, Wolfhart Pannenberg, Jurgen Moltmann, Robert Jenson, and possibly Karl Rahner.

Theism: a brief history.

 Theism is the belief in the existence of one or more divinities or deities (gods), which are both immanent (i.e. they exist within the universe) and yet transcendent (i.e. they surpass, or are independent of, physical existence). These gods also in some way interact with the universe (unlike in Deism), and are often considered to be omniscient, omnipotent and omnipresent.

The word "theism" was first coined in English in the 17th Century to contrast with the earlier term Atheism. "Deism" and "theism" changed meanings slightly around 1700, due to the increasing influence of Atheism: "deism" was originally used as a synonym for today's "theism", but came to denote a separate philosophical doctrine (see Deism).

Theism incorporates Monotheism (belief in one God), Polytheism (belief in many gods) and Deism (belief in one or more gods who do not intervene in the world), as well as Pantheism (belief that God and the universe are the same thing), Panentheism (belief that God is everywhere in the universe but still greater and above the universe) and many other variants (see the section on Philosophy of Religion). What it does not include is Atheism (belief that there are no gods) and Agnosticism (belief that it is unknown whether gods exist or not).

The Abrahamic faiths (Judaism, Christianity and Islam) as well as Hinduism, Sikhism, Baha'i and Zoroastrianism, are all theistic religions.

Pantheism: a brief history.

 Pantheism is the belief that reality is identical with divinity, or that all-things compose an all-encompassing, immanent god. Pantheist belief does not recognize a distinct personal god, anthropomorphic or otherwise, but instead characterizes a broad range of doctrines differing in forms of relationships between reality and divinity. Pantheistic concepts date back thousands of years, and pantheistic elements have been identified in various religious traditions. The term pantheism was coined by mathematician Joseph Raphson in 1697 and has since been used to describe the beliefs of a variety of people and organizations.

Pantheism was popularized in Western culture as a theology and philosophy based on the work of the 17th-century philosopher Baruch Spinoza, in particular, his book Ethics. A pantheistic stance was also taken in the 16th century by philosopher and cosmologist Giordano Bruno. Ideas resembling pantheism existed in South and East Asian religions before the 18th century (notably Sikhism, Hinduism, Sanamahism, Confucianism, and Taoism).

Deism: a brief history.

 Deism (/ˈdiːɪzəm/ DEE-iz-əm ^[1][2] or /ˈdeɪ.ɪzəm/ DAY-iz-əm; derived from Latin deus, meaning "god")^[3] is the philosophical position and rationalistic theology^[4] that rejects revelation as a source of divine knowledge, and asserts that empirical reason and observation of the natural world are exclusively logical, reliable, and sufficient to determine the existence of a Supreme Being as the creator of the universe.^{[3][4][5][6][7][8]} Deism is also defined as the belief in the existence of God solely based on rational thought, without any reliance on revealed religions or religious authority.^{[3][4][5][6][7]} Deism emphasizes the concept of natural theology, that is, God's existence is revealed through nature.^{[3][4][5][6][8]}

Since the 17th century and during the Age of Enlightenment, especially in 18th-century England and France, various Western philosophers and theologians formulated a critical rejection of the religious texts belonging to the many institutionalized religions and began to appeal only to truths that they felt could be established by reason alone as the exclusive source of divine knowledge.^[4][5][6][7] Such philosophers and theologians were called "Deists", and the philosophical/theological position that they advocated is called "Deism".^[4][5][6][7] Deism as a distinct philosophical and intellectual movement declined towards the end of the 18th century.^[4] Some of its tenets continued to live on as part of other intellectual movements, like Unitarianism, and it continues to have advocates today.^[3]

Atheism: a brief history.

 Atheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there are no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists.

The etymological root for the word atheism originated before the 5th century BCE from the ancient Greek ἄθεος (atheos), meaning "without god(s)". In antiquity, it had multiple uses as a pejorative term applied to those thought to reject the gods worshiped by the larger society, those who were forsaken by the gods, or those who had no commitment to belief in the gods. The term denoted a social category created by orthodox religionists into which those who did not share their religious beliefs were placed. The actual term atheism emerged first in the 16th century. With the spread of freethought, skeptical inquiry, and subsequent increase in criticism of religion, application of the term narrowed in scope. The first individuals to identify themselves using the word atheist lived in the 18th century during the Age of Enlightenment. The French Revolution, noted for its "unprecedented atheism", witnessed the first significant political movement in history to advocate for the supremacy of human reason.

Arguments for atheism range from philosophical to social and historical approaches. Rationales for not believing in deities include the lack of evidence, the problem of evil, the argument from inconsistent revelations, the rejection of concepts that cannot be falsified, and the argument from nonbelief. Nonbelievers contend that atheism is a more parsimonious position than theism and that everyone is born without beliefs in deities; therefore, they argue that the burden of proof lies not on the atheist to disprove the existence of gods but on the theist to provide a rationale for theism. Although some atheists have adopted secular philosophies (e.g. secular humanism), there is no ideology or code of conduct to which all atheists adhere.

Since conceptions of atheism vary, accurate estimations of current numbers of atheists are difficult. According to global Win-Gallup International studies, 13% of respondents were "convinced atheists" in 2012, 11% were "convinced atheists" in 2015, and in 2017, 9% were "convinced atheists". However, other researchers have advised caution with WIN/Gallup figures since other surveys which have used the same wording for decades and have a bigger sample size have consistently reached lower figures. An older survey by the British Broadcasting Corporation (BBC) in 2004 recorded atheists as comprising 8% of the world's population. Other older estimates have indicated that atheists comprise 2% of the world's population, while the irreligious add a further 12%. According to these polls, Europe and East Asia are the regions with the highest rates of atheism. In 2015, 61% of people in China reported that they were atheists. The figures for a 2010 Eurobarometer survey in the European Union (EU) reported that 20% of the EU population claimed not to believe in "any sort of spirit, God or life force", with France (40%) and Sweden (34%) representing the highest values.

Sikhism: a brief history.

 Sikhism or Sikhi (Punjabi: ਸਿੱਖੀ Sikkhī, [ˈsɪkːʰiː], from ਸਿੱਖ, Sikh, 'disciple', 'seeker', or 'learner') is an Indian Dharmic religion that originated in the Punjab region of the Indian subcontinent around the end of the 15th century CE. Sikhism is one of the youngest of the major religions and the world's fifth-largest organized religion, with about 25–30 million Sikhs as of the early 21st century . However, according to rough estimates, there are around 120–150 million (12–15 crore) Sahajdhari or non-khalsa Nanakpanthi sikhs across the world who also believe in 10 Sikh Gurus and Guru Granth Sahib.

Sikhism developed from the spiritual teachings of Guru Nanak, the first Guru (1469–1539), and of the nine Sikh gurus who succeeded him. The tenth guru, Gobind Singh (1666–1708), named the Sikh scripture Guru Granth Sahib as his successor, bringing to a close the line of human gurus and establishing the scripture as the last eternal 11th living guru, a religious spiritual/life guide for Sikhs. Guru Nanak taught that living an "active, creative, and practical life" of "truthfulness, fidelity, self-control and purity" is above metaphysical truth, and that the ideal man "establishes union with God, knows His Will, and carries out that Will". Guru Hargobind, the sixth Sikh Guru (1606–1644), established the concept of mutual co-existence of the miri ('political'/'temporal') and piri ('spiritual') realms.

The Sikh scripture opens with the Mul Mantar (ਮੂਲ ਮੰਤਰ), fundamental prayer about ik onkar (ੴ, 'One God'). The core beliefs of Sikhism, articulated in the Guru Granth Sahib, include faith and meditation on the name of the one creator; divine unity and equality of all humankind; engaging in seva ('selfless service'); striving for justice for the benefit and prosperity of all; and honest conduct and livelihood while living a householder's life. Following this standard, Sikhism rejects claims that any particular religious tradition has a monopoly on Absolute Truth.

Sikhism emphasizes simran (ਸਿਮਰਨ, meditation and remembrance of the teachings of Gurus), which can be expressed musically through kirtan, or internally through naam japna ('meditation on His name') as a means to feel God's presence. It teaches followers to transform the "Five Thieves" (i.e. lust, rage, greed, attachment, and ego).

The religion developed and evolved in times of religious persecution, gaining converts from both Hinduism and Islam. Mughal rulers of India tortured and executed two of the Sikh gurus—Guru Arjan (1563–1605) and Guru Tegh Bahadur (1621–1675)—after they refused to convert to Islam. The persecution of Sikhs triggered the founding of the Khalsa by Guru Gobind Singh in 1699 as an order to protect the freedom of conscience and religion, with members expressing the qualities of a Sant-Sipāhī ('saint-soldier').
