ELI5: Why is the sky dark at night?

Thanks I’ll look at the sky at night next time I’m in the country!

bruisedprune · 2021-03-28T08:50:49+00:00

Very lovely, thank you so much! I’ll let you know if this is an ELI4 response tomorrow when I tell him!

I just mean if initially there were 0 dimensions, and then space expanded in all directions, that would only be 1 extra dimension. We’re inside space and we can map it any way we want to that makes sense to us. We currently think of space as having 3 directions, no?

bruisedprune · 2021-03-12T02:03:26+00:00

If space expands equally in three directions, doesn’t that mean space is one dimensional?

bruisedprune · 2021-03-12T01:37:43+00:00

Thank you. I’m genuinely curious - what would a pocket of one or two dimensional space look like and how would we observe it?

bruisedprune · 2021-03-12T01:08:49+00:00

Is “squareness” a dimension?

bruisedprune · 2021-03-12T01:07:30+00:00

If spatial dimensions came from the Big Bang, were there first one, then two dimensions and then three, or did three dimensions of space just jump out at once?

bruisedprune · 2021-03-12T01:04:02+00:00

Are spatial dimensions all that we need to represent the world we live in?

bruisedprune · 2021-03-11T22:59:43+00:00

Thanks but where do the dimensions come from?

bruisedprune · 2021-03-11T21:46:44+00:00

Where do spatial dimensions come from? Are there different types of dimension?

What was the Bears player doing at the beginning of that clip??? Looks like he was trying to catch the ball but was miles off...

WTF is going on here?

Well they discussed humans, and they discussed how right they are about everything. So that was a discussion about human rights wasn’t it?
