Before the big bang - what could we know?
Imagine that you hear that a famous scientist has published a paper that reveals that he has found evidence that confirms his theory about what happened before the big bang. Without reading the paper, you speculate on what the evidence was and how that might confirm any theory.
Is there any chance that we will know - even with doubt - what happened before the big bang? What evidence would support our knowledge?

The Big Bang physically cut off any history of what could be before it, if the concept of before even makes sense without time as a dimension.
It makes no sense to have much of a discussion about what cannot be known.
For more about the Big Bang and its implications, watch the video at the 1st link - "A Universe From Nothing" by theoretical physicist Lawrence Krauss, read an interview with him (at the 2nd link), or get his new book (at the 3rd link). And, see the 4th link for "The Universe: Big Bang to Now in 10 Easy Steps."

The Big Bang is explained by String Theory. Since string theory contains the belief of a multi-verse, they believe there are many universes. Imagine all the universes as bubbles. When bubbles collide, they form one new universe, and the bubbles can also split to create new universes. That is what physicists think is the Big Bang, the splitting and collision of universes. Eventually our own universe will come to an end, and the only way to escape would be to go into a worm-hole.

Our current physical understanding of the Big Bang is that it was the beginning of time as well as everything else. So the concept of "before" the big bang may well be entirely meaningless.
The only possible way you might be able to prove otherwise would be like so: if other universes exist, and come into existence from time to time, then you might be able to observe one coming into existence at some finite point in our time. So in that sense, there could be a "before" and "after" the big bang for that universe, and by extension there would probably be one for ours as well.
That said, even that would only have a "before" and "after" as defined by time-keeping in another universe. Whether or not that has any physical relevance to our own universe is debatable at best.

There is no before the big bang because the universe used to be a singularity ( a superduper dense small point). Time doesn't exist in our universe before the big bang. For more evidence mail me anytime

Not with the current scientific evidence. Our evidence only tells us what we see now, and leads back to conditions AFTER the Big Bang expansion began.
