So I was doing a little research on dark energy and was somewhat startled at what I found, while I new the universe was expanding, it was surprising to know what from. Also I have a big question as I can't figure out what's after that, so what I'm trying to say is that if the universe is expanding doesn't that mean it has to have an end in the first place to even expand? So if their is an end to the universe than whats after that end? And if their isn't, well maybe someone could explain to me why? Hey thanks for your help, and I know I'm new here and also a little young, but I love science!

" dark energy

meet the nobel laureates exploring the universe's biggest mystery "

page 38.

 

from what i have gathered so far is it's about the expansion and it ripping the universe apart.

 

3 ending scenario

1 big crunch

2 big rip

3 knife edge

 

on one of the page it has a diagram,

 

it shows,

 

5% normal matter of the universe

24% dark matter of the universe

71% dark energy of the universe

Well thanks, ill have to take a lo

 

Well thanks, ill have to take a look at that.

no problem at all.

It's not expanding at an "outer edge" but between every point. The typical example used is the surface of a balloon. When you blow up the balloon, the surface expands, but it doesn't have an outer edge that it's expanding from. Similarly, universal expansion is the expansion of space at every point in the universe, not the growth of the universe into some sort of non-universe space.
