The temperature at the time of the Big Crunch is expected to mirror that of the Big Bang, potentially reaching the Planck temperature of approximately 142 million million million million million Kelvins. At this extreme temperature, atomic structures would not be able to exist, making the survival of any life forms impossible. The discussion emphasizes that the conditions during the Big Crunch would be inhospitable to life as we know it. Ultimately, the Big Crunch signifies a return to a state where life cannot endure.

What will be the temperature at the time of big crunch? and will any life form survive at the time of big crunch?
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.
Partial solar eclipse from Twizel, South Isl., New Zealand ...
almost missed it due to cloud, didnt see max at 0710 NZST as it went back into cloud.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons.
Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
