AI Thread Summary
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?
 
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.

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
