”The observable universe was once compressed into a volume the size of a golf ball, but that golf ball was only a tiny piece of a universe that was infinite even then.”
What a helpful way of thinking about it. I’m surprised I’ve never heard this before. Mind expanding, no pun intended.
- aasasd 4y agoRather the opposite for me, I'm now even more confused about what was where. Not that I quite get the picture of an infinite universe anyway, which I guess is the prerequisite here.
- danwills 4y agoAgreed, so helpful! There's logical traps one can easily fall into (I frequently realise I'm making this mistake when trying to think of the concept of the universe) where my mind seems to want to be able to 'enclose' the universe as if it were an object so it can be referred to, like a golf ball. But I understand the concept to mean everything, all objects/information, no exceptions, and then the idea of anything outside that becomes problematic, but the golf ball is only the light that has reached us so far, and maybe the universe is really spatially infinite outside that too? How could we find out? Fascinating! great read!
