:: galaxies collide
My colleague showed me some amazing pictures of galaxies colliding. Scary stuff, these tiny pictures of systems so enormous. But it is food for thought: if planets and galaxies do the same things that atoms and electrons do in a much tinier spectrum.. What if every electron in our world would be a galaxy, and our world merely an electron in another world - and what if that is how the universe is indeed infinite? Hmm..
