The author took a few too many artistic liberties for my taste, also some things are just plain wrong (accelerated expansion phase shows galaxies and talks about space expanding to remove galaxies forever out of sight after explaining that all the universe is now black dwarves), but some nice ideas are presented & I watched it to the end.

I agree with you; also they say the accelerated expansion of the universe will pull galaxies away at the speed of light but then later claim that black holes can still merge after that.
Right, I was a bit confused by the very late black-hole merging logic. I had the impression that the authors added some 10^30 years to the universe that were pure speculation :D I was able to check that proton decay at least was correctly timed in the video - as per wikipedia it seems that protons have a speculated half-life of 1.67×10^34 years
I get what you're saying, but in my opinion, while the video is indeed not perfect from a strict scientific point of view, it's still accurate enough, and sometimes I think it's necessary to sacrifice a bit of accuracy to make things simple and comprehensible to most.
I think the purpose of the one making the video was not to make a lesson in astrophysics, but a presentation in broad terms of what we know now in a way that's thought provoking, that it does exceptionally well IMO.
I agree that it took a few too many artistic liberties for my taste, but I'm also biased since I'm doing my PhD in the field. I've loved melodysheep since I was a teenager (our story in one minute earned my sub), and all of his videos just have the best vibes/music/visuals. I genuinely have rewatched this video 10+ times in the last few years because of how it makes me feel, even if I have to turn my brain off a little. I hope it's just as nice for other people, and it seems it is
as I said, I watched it to the end :) it's not bad.
This is pretty mind blowing.
Yeah, beautiful and terrifying and the same time.
8 minutes in and I thought it was ending soon... yikes
