BEGINNING OF THE UNIVERSE
There was of course, no ''bang'', big or small, because there was no medium in which sound could exist. It was the beginning of time, space, matter, energy, everything - all inexplicably created out of a ''singularity'' in which none of these existed before. In the 1960s, scientist detected the echo of the Big Bang in the form of background radiation from across the sky. impressively, they have produced a theoretical explanation of what must have happened in the very first second of the universe. When the universe was still tiny and incredibly hot, a sudden expansion occurred as matter moved from the minute quantum scale to that of a small but growing cosmos. Vast amounts of matter and antimatter were created, almost all of which mutually annihilated, leaving just a tiny portion matter. As the universe cooled from its enormous levels of energy, subatomic particles assembled. It was not for another 380,000 years that temperatures fell sufficiently for electrons and protons to come together to form atoms.
Vast cloud of hydrogen collected, cohering into ever - denser masses that compacted under the force of gravity until hydrogen atom at the center fused into helium, releasing energy that made them bum as stars. When some of these exploded into supernovae, heavier atoms were made, which form the raw materials for the universe as we know it.
The theory of Big Bang was put forward in the 1950s, and it is still the unchallenged scientific explanation of the origins of the universe.
