Our universe is not forever. We know that our universe is expanding, and the galaxies of the universe are getting further and further away. In this second video on the timeline of the universe, we look forward, and analyse the possible ways in which the universe may come to an end, and the science and evidence behind each.

Part 2/2 of my 200K subscriber special- we've gone from the start of the universe right the way through to the end. Thank you very much for watching, and thank you especially to those who have been there with me through my journey, from a tiny naff gaming channel into the operation it's become today :) I love you all!
