Why call the beginning of this earth the big bang

Question

Why call the beginning of this earth the big bang

Answer 1

We don't call the beginning of the Earth the Big Bang.  It was the beginning of the Universe that is called the Big Bang.   It is called that because science believes that just before the Big Bang there was a very tiny condensed particle of energy.  When the energy got to be too great it exploded as a Big Bang and continued to expand into our universe and continues to expand today.

Answer 2

The big bang was not the beginning of the Earth.  The big bang was the beginning of the universe, the beginning of space and time.  The Earth wasn't formed until 9.2 billion years after the big bang, about 4.5 billion years ago.

Answer 3

"Big Bang" sounds like an appropriate enough name for the most gargantuan explosion imaginable, the most energetic event in the history of the cosmos.

Answer 4

The Earth was *NOT* created in the Big Bang! The Big Bang created the Universe and the matter and energy contained within it. The Earth formed later, out of this matter.

The reason why we call it the Big Bang is because it was the most energetic event in the history of the Universe. It was NOT an explosion, so the name is actually rather poorly chosen. People tend to ask (especially in R & S), "if the big bang created space, what was outside the universe before the big bang?" This reveals their ignorance, but sadly it may not even be their fault.

The Big Bang was merely the expansion of space i.e. the increase in volume of the universe. The universe is a closed system with "nothing" outside.

Answer 5

because there was a "big" explosion that had a "bang" sound which started the universe expanding and earth formation... ROFLOL

Answer 6

It's called the Big Bang because when the theory first came out it's leading critic, Fred Hoyle, said "Oh that's just a big bang!"

His comment was meant to make fun of the theory but it stuck and is still used even though it's extremely confusing because THERE WAS NO EXPLOSION big or small.

It was an expansion of an unimaginably dense "singularity". An expansion of time and space.

Our latest figure for the age of this expansion is 13.7 billion years. Our solar system, including the earth were created about 4.6 billion years ago.

"The term 'Big Bang' was apparently first coined by Fred Hoyle in a derisory statement seeking to belittle the credibility of the theory that he did not believe to be true."

Answer 7

but how can there be nothing, what is nothing, can something really just end?  with nothing left beyond that?  wait i should be answering the question, not asking more, ah well, what's his face already did that up above, so ..... i got "nothing"

Answer 8

A Theory of scientist, but not necessarily how it happen.
