I recently learned of a very interesting (though almost certainly not true) theory that the early universe teemed with life because there was a brief (some number of the millions of years, I believe) period where the space of the universe itself was at standard temperature and pressure.

I love this channel if you're interesting in astro physics, astronomy, cosmology, etc. 

 Isaac Arthur is a gem. Highly recommend.  

 Love him too!
