 There are super interesting questions that are raised just by the sort of possibilities that cosmologists come up with, things like the multiverse for example. If there is just an infinite multitude of different universes spread out across different dimensions then again it just makes the whole way we think about, it forces us to reconsider the way we think about the value of a state of affairs. Do you think that you do something and it brings about some value and then you think well, but if I live in a multiverse then there's infinite value and there's infinite disvalue, in fact the overall value of the state of affairs is undefined because if you add positive to infinite negative you get an undefined sum. So what does that mean, what does that mean matter? It's all pointless. I can't make any difference at all to the universe. And again that forces you to think well okay so obviously what we care about isn't just the overall value of states of affairs. So I think that on the one hand there's the acquisition of knowledge which is obviously important and there's the sort of preservation of curiosity but also just the kind of the creativity that we get from thinking about these possibilities, the different, the different possible alternatives that are raised by some of this advanced work, some of it advanced work in physics enables us again just to sort of push and pull and tweak at the things that we think about in the world that we actually live in. So as long as that sort of creative thinking is happening even if we don't find out sort of, even if we never get to space exploration, real space exploration in our life sounds like something that seems sort of consequentially different from what we've already done so far. Just the ability to think it through has tremendous benefits for us.
