Question

what was before the big bang

Answer 1

Stephen Hawking has said that "Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang. Events before the Big Bang, are simply not defined, because there's no way one could measure what happened at them."

However, pre-big bang singularity might have emerged or preceded by possibly certain events, such as:[2]

O:A white hole, a hypothetical body which emits massive energy and matter rather than absorbing it in.

O:A big crunch, a cycle of big bounce comes after the universe expansion.

O:A cyclical universe, an event happens when two extra-dimensional membranes, or branes, collide in a zone outside our universe; in relation to string theory.
