what is Big Bang Theory
Answers
Answer:
Explanation:
The big bang theory describes the development of the universe from the time just after it came into existence up to today. It's one of several scientific models that attempts to explain why the universe is the way it is. The theory makes several predictions, many of which have been proven through observational data. As a result, it's the most popular and accepted theory regarding our universe's development.
The most important concept to get across when talking about the big bang is expansion. Many people think that the big bang is about a moment in which all the matter and energy in the universe was concentrated in a tiny point. Then this point exploded, shooting matter across space, and the universe was born. In fact, the big bang explains the expansion of space itself, which in turn means everything contained within space is spreading apart from everything else.
At the earliest moments of the big bang, all of the matter, energy and space we could observe was compressed to an area of zero volume and infinite density. Cosmologists call this a singularity.
Answer:
The Big Bang Theory is the leading explanation about how the universe began. At it simplest, it says the universe as we know it started with a small singularity, then inflected over the next 13.8 billion years to the cosmos that we know today.
