Pe măsură ce ne apropiem de sfârșitul Crash Course Astronomy, acum este timpul să recunoaștem că zilele Universului nostru sunt numărate. Stelele se vor stinge după câteva trilioane de ani, protonii se vor descompune și materia se va dizolva după o mie de trilioane de trilioane de ani, găurile negre se vor evapora după 10^92 de ani și apoi toate vor fi întunecate. Dar există încă speranța că din el se va naște un nou Univers.

I am more scared of what we don't know
This gives me anxiety
“The” should be replaced with “Our”
Cold , and empty !
I like it that way .
I hope that in the afterlife you can’t feel time pass. No matter how I look at it this video gives me existential dread lol. But I love it!
isnt everyone just earth since when we are born we know we will be buried.
Time keeps on slipping into the future
Maybe it's humans' job to prevent the big freeze.
hey crash course, do you have any recommended readings for an adult with no astronomically educated background who has become incredibly interested by this series?
But… doesn’t the zeroth dimension suggest that when the universe “dies” it will “go backwards” and be “reborn”?
Yes!!!! The zeroth dimension. Basically, The universe just keeps dying and being reborn over and over. I heard somewhere its like the universe expanding then imploding. Whats too say its going “forward” now and backwards later. Or vice versa.
What if space time is like a rubber sheet and the Big Bang is why it’s stretching along with everything else, but at some point it stops stretching and starts contracting slow at first then increasingly fast until it all comes back to a point of singularity starting the whole process all over again
