After the Big Crunch, will the universe or multiverse support Life?

Well, considering that it is a Big "Crunch" and that the universe will have shrunken down to a point that all known physics disintegrates, I'd say no.

Tachyons?
I'm honestly not sure what those kinds of particles would have to do with the collapse of an entire universe.

I guess,Nothing! But there must be something like Tachyons having v=c... Right?

Tachyons are particles where the case of $v > c$ always applies. Their velocities are always faster than $c$ and they are forbidden from traveling any slower.

Oh Yeah, I forgot that... Sorry :)

If they exist, they exist within the universe, and if there's a Big Crunch, the universe ends, along with everything within it. So the answer to your question remains "no", as Lambdaenergy said.

Let me venture a guess. You think of the tachyons as having space-like world lines. And since the final singularity of the big crunch is space-like it might contain space-like curves i.e. tachyons. But the singularity is not part of space-time so the answer is no.

Thank you all for your answers! It helped me a lot... :D
