Well, for starters, if you take everything that is expanding at this moment and reversed it, everything would end up back to a very small dense object. Besides, the big bang explains a majority (not everything) of what is happening around us in great detail.
The big bang occurred approximately 13.7 billion years ago.
The big bang occurred approximately 13.7 billion years ago.
The event that marks the beginning of the universe is the Big Bang. This was a cosmic event that occurred about 13.8 billion years ago, creating the universe as we know it today. The Big Bang theory is widely accepted by scientists as the most plausible explanation for the origin of the universe.
The Big Bang! Space-time did not exist before the Big Bang so there can be no earlier events.
What explosion And if you are talking about the Big bang it happened about 13.7 billion years ago
Everything we know of happened after the Big Bang.
The Big Bang.
According to the believes of physics and the big bang, we know that the big bang was both big and a bang. Since we are still receiving radiation from the big bang, So considering that factor I would say that it was big and a bang. What do you believe?
The Big Bang is thought to have occurred roughly 13.8 billion years ago. This event marked the beginning of the observable universe and set in motion the expansion of space and time as we know it.
The Big Bang is the cause of everything we know - the Universe around us. If the Big Bang itself was caused by something else, we don't know about it.
Everything that ever happened - or at least, everything we know of - happened after the Big Bang, and was, in a way, affected by the Big Bang.
The ages don't match. The Bing Bang occurred some 13.8 billion years ago; the Solar System has an age of about 4.6 billion years.
