Super interesting, if not a little depressing. But as this happening is not likely to occur next week or anything, it is not something I am going to worry about.
It is a shame though when you think about how much we humans have learnt and will continue to learn in the future, for it all to just end. Will there be any saving the planet with the intelligence they collect between now and then?
Next time you write can you do something about black holes, other universes or maybe even aliens.
Thanks for your post
