Hello. I thought this might do better here, as it's a maths question. If I were to scale down the size of the known universe to the size of our planet, would anyone know how much of the planet we would occupied on this scale? I'm assuming it's a very small space. Perhaps a better comparison might be to our galaxy. How much of a galaxy would we occupy, if that galaxy were shrunk to planetary size? I hope this question makes sense, and I just think it's an interesting comparison.
