English astronomer Fred Hoyle is credited with coining the term "Big Bang" during a talk for a March 1949 BBC Radio broadcast, [45] saying: "These theories were based on the hypothesis that all the matter in the universe was created in one big bang at a particular time in the remote past." [46] [47] However, it did not catch on until the 1970s ...
In medieval philosophy, there was much debate over whether the universe had a finite or infinite past (see Temporal finitism).The philosophy of Aristotle held that the universe had an infinite past, which caused problems for past Jewish and Islamic philosophers who were unable to reconcile the Aristotelian conception of the eternal with the Abrahamic view of creation.

The elements of the universe are created, used by Brahma, and fully dissolved within a maha-kalpa (life of Brahma; 100 of his 360-day years) period lasting for 311.04 trillion years containing 36,000 kalpas (days) and pralayas (nights), and is followed by a maha-pralaya period of full dissolution equal in duration.
The Big Bang theory, which explains the Evolution of the Universe from a hot and dense state, is widely accepted by physicists.. In astronomy, cosmogony is the study of the origin of particular astrophysical objects or systems, and is most commonly used in reference to the origin of the universe, the Solar System, or the Earth–Moon system.
In 1948, Fred Hoyle set out his opposing Steady State theory in which the universe continually expanded but remained statistically unchanged as new matter is constantly created. These two theories were active contenders until the 1965 discovery, by Arno Allan Penzias and Robert Woodrow Wilson, of the cosmic microwave background radiation, a ...
The physical universe is defined as all of space and time [a] (collectively referred to as spacetime) and their contents. [10] Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space.
The legislation allows public school teachers to answer student questions "about scientific theories of how the universe and/or life came to exist.” It was proposed after Republican Senate ...
Other theories suggest that they may have included small stars, some perhaps still burning today. In either case, these early generations of supernovae created most of the every day elements we see around us today, and seeded the universe with them. The lookback time of extragalactic observations by their redshift up to z=20. [8]
