What is science consensus about origin of universe?

Most people follow the doctrine of a beginning to time called the Big Bang. Most scientists agree with the Big Bang as the most probable theory, it is afterall, just a theory.

 

Ok. Actually I would like to know, which thing had made to happen the Big Bang. What has existed before the Big Bang?

What we know of the big bang is based on general relativity.

 

The singularity theorems of Hawking and Penrose show that it is impossible to indefinitely extend timelike geodesics into the past. That means that, within the context of general relativity, there is no such thing as "before the big bang".

 

An no, this is not "just a theory". It is a logical consequence of what is actually observed (that the universe is expanding and has at least a minimal matter content) and the general theory of relativity, which is also supported by a great deal of evedence. What is a theory (not "just a theory") is the general theory of relativity. To call something a theory is to say that it has proven predictive power and is consistent with what is actually observed. A theory is NOT a conjecture. It is not gospel, but it is much more than mere musings.

At first, Hellobiggrin.gif to you (I have seen you, at different science forums).

 

 

You mean before bigbang the universe (or anything) was not exist. You mean it is the first universe ever.

Do you not think it opposes conservation law.

 

(what is the geodesics?)
