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
