Big Bang Theory for Beginers

Let’s learn about Big-Bang theory

Stephen William Hawking (1942 - 2018) was the former Lucasian Professor of Mathematics at the University of Cambridge and author of A Brief History of Time which is an international bestseller. He was the Dennis Stanton Avery and Sally Tsui Wong-Avery Director of Research at the Department of Applied Mathematics and Theoretical Physics and Founder of the Centre for Theoretical Cosmology at Cambridge, his other books for the general reader include A Briefer History of Time, the essay collection Black Holes and Baby Universe and The Universe in a Nutshell.

Since the emergence of the Big Bang theory as the dominant physical cosmological paradigm, there have been a variety of reactions by religious groups regarding its implications for religious cosmologies. Some accept the scientific evidence at face value, some seek to harmonize the Big Bang with their religious tenets, and some reject or ignore the evidence for the Big Bang theory.

repeated by supporters of the steady state theory,^[10] who rejected the implication that the universe had a beginning.^[11]^[12]

The view from the Hindu Puranas is that of an eternal universe cosmology, in which time has no absolute beginning, but rather is infinite and cyclic, rather than a universe which originated from a Big Bang.^[13]^[14] However, the Encyclopædia of Hinduism, referencing Katha Upanishad 2:20, states that the Big Bang theory reminds humanity that everything came from the Brahman which is "subtler than the atom, greater than the greatest."^[15] It consists of several "Big Bangs" and "Big Crunches" following each other in a cyclical manner.^[16]^[17]^[18]

The Nasadiya Sukta, the Hymn of Creation in the Rigveda (10:129) mentions the world beginning from a point or bindu, through the power of heat.^[19]^[20] This can be seen as corresponding to the Big Bang theory.

Several prominent modern scientists have remarked that Hinduism (as also Buddhism and Jainism by extension as they share most of these philosophies) is the only religion (or civilization) in all of recorded history, that has timescales and theories in astronomy (cosmology), that appear to correspond to those of modern scientific cosmology, e.g. Carl Sagan,^[21] Niels Bohr, Erwin Schrödinger, Werner Heisenberg,^[22]^[23]^[24] Robert Oppenheimer,^[25] George Sudarshan,^[26] Fritjof Capra^[27] etc.
