" What's interesting if you look at the basic physics of the universe going from the Big Bang to where we are today, is that the physics is driven by the fact that the universe began in an extremely ordered state. See, it was a very highly ordered system. And it is tending towards a more disordered system at the moment. And that's called the second law of thermodynamics. What we strongly suspect, and I would say know, is that in that processes of going from order to disorder, complexity emerges naturally for a brief period of time. So it's a natural path that in the evolution of the universe you get period in time where there's complexity in the universe - stars, and planets, and galaxies, and light, and civilisations. But they exist because the universe is decaying, not in spite of the fact that the universe is decaying. So our existence in that sort of picture is necessarily finite and necessarily time limited. And it is a remarkable thing that that complexity has gone so far, that there are things in the universe that can think, and feel, and explore it. And I think that is the answer. If you want an answer to the meaning of it all, it's that. That you are a part of the universe because of the ways the laws of nature work. You are allowed to exist, but you are allowed to exist for a temporary, small amount of time in a possible infinite universe. "
