Forums - General - Big bang - Planck probe gets clearest glimpse yet of cosmic dawn.

How do they know it's the afterglow of the big bang, exactly?

Oooh. Fun nerdy terminology!

Multiple universes nor extra dimensions surprise me completely. I mean, there must be space outside of the universe, an infinite void that may be populated with other universes. And extra spatial dimensions are impossible to physically comprehend, but I'm sure there are more than three.

What I'm interested in is if this is proof of the Big Bang.

EDIT: Do the extra dimensions mean spatial dimensions or am I making an ass of myself?

I'm pretty sure that general relativity says there is no space outside of thhe universe - it's just the universe.

What? The universe is expanding, correct? That means for it to be expanding, there must be space for it to expand into, correct?

I don't claim to under relativity - but no. There is no space except where there is the universe. The universe expands space, rather than expanding into it.

I think.

???

Then how could there be extra universes if there is no space outside of the universe?

When the universe was the size of a dot, there was nothing outside that little dot?

Well assuming there are other universes I would suppose that they each have their own self contained space as well.

But yes, to the best of our knowledge there was nothing outside of that little dot. And by nothing I mean no dimensions.

This is very, very confusing.

Welcome to physics!

Yeah. I still can't get my head around how an electron in the double slit experiment can go through both slits at the same time and interfere with itself. I definately can't get my head around why observing it stops it from happening.

The best thing about physics is that I understand very little of it (outside of everything you could learn in high school and in A Brief History of Time) and it still manages to scare the Hell out of me. I can only iagine what sort of madness must come with greater understanding.
