Gotya!!! Science has not tested the big bang...and never will because they admit they do not know why and how the singularity began. If you think otherwise..provide a reference. And please don't bother to do your normal copy and paste 'post time = 0' red shift and CMBR material as it is not germane to the begining... The fact that science admits that they do not know how 'time = 0' occurred, and that it can't be tested, means the big bang theory is not falsifiable... Of course you can claim that even though the theory relies on an yet untestable beginning, because the possibility remains that 'time = 0' may be disproven, the theory remains falsifiable.. This is not a reasonable understanding of the meaning of falsification in the context of scientific theory...You seem to have different definitions to how science define them.
Either you don't understand what "falsifiable" mean or you don't know that there the Big Bang has already been falsifiable since the early 30s (with redshift), 1964 (with discovery of Cosmic Microwave Background Radiation, that was predicted back in 1948). The Big Bang nucleosynthesis have to occur, otherwise there wouldn't be no matters, no atoms, no stars, etc.
Falsifiable is define as any statement, hypothesis or theory being able to be testable and refutable.
The Big Bang has been tested. There are evidences to support it.
But you keep wanting to add something that's not part of theory, AND that is largely theoretical and untestable with the "something-out-of-nothing". That you would say the Big Bang is not falsifiable, just because something-out-of-nothing isn't testable, don't make the whole Big Bang fall apart.
Scientists don't know much of what happen before the Big Bang, eg the singularity, they can only speculate, and speculating is not a fact.
You quoted Steven Hawking:
Hawking is a brilliant theoretical physicist, but what he said here about the time only apply to the universe as we know it, because if there is a singularity before BB, then what he stated in his conclusion, may seem logical, may even be provable - mathematically - but it is not verifiable until we can actually test his claim.
Yes, I agree with Hawking's statement that is the beginning for our universe, therefore the time is finite here, but if there is a singularity, then he can in any way certain that time didn't exist.
And for your information, if there is a singularity, that means there isn't "nothing" before BB.
I don't know what is Hawking's stance on singularity, but you can't have nothing and singularity. A singularity is something, just that no scientist, including Hawking, can do except speculate and theorise about it.
Where is your scientific proof that there is not no time and no space (nothing) from which the singularity arose? And where is the scientific proof wrt the reason why the singularity arose?
So if you say that science can only speculate about why and how the singularity arose, then how can you claim big bang theory is falsifiable? How can skeptical scientists falsify a theory based on a speculated beginning?
Now if you disagree with anything I've said...quote me precisely and address my remarks with relevance...no digression on 'post time = 0' aspects of big bang theory...
