In 1948, Gamow predicted that the radiation from the big bang nucleosynthesis must still be filling the universe.
The universe expanding can branch of to even more theories... If that is true then that mean there could be entirely different worlds with maybe living creatures living there maybe even a difference species of human....
The theory really starts by saying there was nothing and then there was something, this is because it is really unknown what existed before....
[tags: Universe, Big Bang, General relativity] - According to the American heritage dictionary of English language, the big bang theory is a scientific theory describing the origin of all space, time, matter, and energy approximately 13.7 billion years ago from the violent expansion of a singular point of extremely high density and temperature.
During that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead, and it was insanely hot and dense.
Out of nowhere this little bubble started expanding.
This theory was further boosted by the Arno and Penzias Wilson’s discovery of cosmic microwave radiation, which is believed to be the tangible remnant leftover light from the big bang.... Hubble observed that the universe is expanding in every direction, which makes us come to the conclusion that the universe was once compact and is now moving away from the point of origin.
Since the universe is thought to have come from a singularity which is said to have a extreme heat in it, it was believed that there should be a background heat still in existence in the universe.
[tags: universe, relativity theory] - Weaknesses of the Big Bang Theory The big bang theory was first suggested by a Belgian priest named Georges Lemaitre in the 1920s, when he suggested that the universe began from a single primordial atom.
However the big bang theory was born from the observations which were made by Edwin Hubble that other galaxies were moving from earth at a high speed in different directions.
