Time itself did not exist before the big bang. You can say the singularity *always* existed, and that it existed for no time at all, and be correct both ways.

Bboy Physics said:There WAS time before the big bang, but it is extremely insignificant. Read on A Brief History of Time by Stephen Hawking which delves into this very concept.

Naveen345 said:when a singularity can exist at the centre of a black hole ( this is what rigorous mathematics proves), what can't it exist before the big bang?
Nonsense. "Rigorous mathematics" cannot prove anything about physics. And I doubt that any intelligent mathematician would want to express an opinion as to what a mathematical "singularity" would mean physically.Naveen345 said:when a singularity can exist at the centre of a black hole ( this is what rigorous mathematics proves), what can't it exist before the big bang?
