I think it is weird that the galaxy neverends. It's creepy

[Deajh]

Its is weird, but maybe it does end !

[~Rachy~]

I'm really interested in this kind of stuff Cool thread!

I don't think it's the Galaxy that never ends, it's the universe that keeps expanding and therefore could be said to never end, I suppose I'm really interested in this stuff, I'm glad someone's made a topic for it.

Yup! The galaxy is 100,000 light years across (it takes light 100,000 years to get from one side to the other) and is 1000 light years thick. Depending on the geometry of the Universe, the Universe could go on forever... or when you reach the "edge" of it you disappear and reappear on the other side! So if you go fast enough in a straight line you'll get back to where your started. (Bit like a map of the world having edges but the world itself not.) which is bizarre!

I have an exam on friday in astrophysics, so fire questions and I will try and answer them along with everyone else. Because I have to know a lot of random things and I adore this subject so much! =)

Yay! Pretty big, isn't it?
I'm interested in the whole thing about what shap the universe is as well, if it's circular or doughnut- shaped or some multi- dimentional shape we can'd picture in our three- dimentional little minds O_o
