Did Some Black Holes Survive the Big Bang?

Posted by samzenpus on from the in-the-beginning dept.

astroengine writes "Could anything survive from one universe to the next, through a Big Crunch and resulting Big Bang? According to two researchers, a special class of pre-Big Bang black hole may have the ability to traverse the Big Bang singularity. The upshot is that there may be black holes that existed before the Big Bang knocking around in our modern universe. What's more, we might be able to detect them through the theorized gamma-ray burst produced when these pre-Big Bang black holes evaporate out of existence. But how would we distinguish between these black holes and the primordial black holes thought to be produced after the Big Bang? Well, that's just too confusing right now."

    So there may not be multiple big bangs. In which case their ability to survive is moot.
