    The temperature will probably be the same as that at the big bang, since the big crunch is more or less the big bang in reverse.

    That being said, a good guess would be that the temperature would be the planck temperature, or about 142 million million million million million Kelvins.

    At this temperature no life could exist, since no atoms could exist.
