SUMMARY

The temperature at the time of the Big Crunch is expected to reach the Planck temperature, approximately 142 million million million million million Kelvins. This extreme temperature mirrors the conditions of the Big Bang, suggesting that the universe will undergo a catastrophic collapse. At such temperatures, atomic structures cannot exist, rendering any form of life impossible. Therefore, survival of any life forms during the Big Crunch is unequivocally ruled out.

PREREQUISITES
  • Understanding of cosmology and the Big Bang theory
  • Familiarity with the concept of the Planck temperature
  • Knowledge of atomic structure and its limitations at extreme temperatures
  • Basic principles of thermodynamics in relation to the universe
NEXT STEPS
  • Research the implications of the Big Crunch on cosmic structures
  • Explore the relationship between temperature and atomic stability
  • Study the Planck temperature and its significance in physics
  • Investigate theories surrounding the fate of the universe
USEFUL FOR

Astronomers, physicists, and students of cosmology interested in the ultimate fate of the universe and the conditions that govern life and matter at extreme temperatures.

What will be the temperature at the time of big crunch? and will any life form survive at the time of big crunch?
 
Astronomy news on Phys.org
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.
