Big Crunch

  1. Jan 4, 2015 #1
    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.

    Then what about 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 [itex] v > c [/itex] always applies. Their velocities are always faster than [itex] c [/itex] 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
