Alas, Our Cosmos Is so Small

Tantalising evidence hints Universe is finite

Perplexing observations beamed back by a NASA spacecraft are fuelling debates about a mystery of biblical proportions - is our Universe infinite? Scientists have announced tantalising hints that the Universe is actually relatively small, with a hall-of-mirrors illusion tricking us into thinking that space stretches on forever.

Ok, so if the universe is finate, then it stops at the edge, right? Imagine a ball, suspended in the air infront of you. Now, you are inside the ball, and it is hollow. Now look up and see where the edge of the ball is from the inside. That is the furthest out the ball stretches. So whats beyond the outside of the ball? Space. If the universe in my example was the 'ball' then there has to be something behind it, even if it is just a huge amount of space, that goes on forever. What would you call that space? If it goes on forever, regardless if it is solid matter or not, it is still an entity outside it.

Bacicly, what I am trying to say is, if you say the 'Universe is finate' then the universe must be in something that is infinate. Like a lone ball in the middle of an infinate sheet of nothing.

Sounds like the boys at NASA need to dig into a tantalizing 4th grade english book if they think tantalising is a word.

A valid point indeed.

Or one "ball" in a giant "bag" with other "balls" (think how one carries a bunch soccer balls in another bag). Who's not to say that outside our universe isn't others like ours in an even bigger universe?

Hey, leave the poor guy alone. English is not his first language, he is currently learning it and trying it out in these boards. And his spelling is better than mine usually is!!!

Indeed. That goes in line with 'N' (or is it 'M'??) theory that says that our universe is one of many.

I think the exact theory is that these 'universes' start out as 'sheets of membrane'. When two or more collide, they form what we think of as 'the big bang', thus creating the universe as we know it today. I, obviously, am no expert (at all) but it's certainly a facinating idea.

Only seven billion light years wide? And here I was thinking it was huge or something..

Actually according to the article:

If confirmed, they would indeed be stunning. They would mean that the Universe is relatively small, something like 70 billion light years across. What's more, we could in theory see the entire cosmos and check that there are no hidden corners where the laws of physics are different.

So it's 70, not 7. haha

Those who want to think what is outside of our universe should read Stephen Hawkins' books about universe.

Hawkins has told us that thinking is a trap! :)

M theory .. Dr. Edward Witten invented that theory. M stands for ...Magic, Mystery or Matrix theory.

He unified the 5 different string theories and came up with M theory and 11th dimension !! :wacko: :wacko:

here check this out ..

The universe might be finite but I'll bet this thread could be infinate if given the chance ;)

EDIT: I have so many ideas, if i posted them I'd waste so much time, so I wont worry. But I would rather an infinate universe i think.

:D (Y) Yeah! Gee *pfft* just Seventy Billion light years wide. Man that is so tight. :wacko:

I wish the money was diverted away from those time / money wasting scientists and maybe spent on finding cures for cancer or AIDS.

Really, who gives a flying bass how big the universe is? :|

well, according to this, if i see the north star in one part of the sky, i can go to the polar oposite of hte earth and see the same star at the same angle, use the north star, is it visible in the south? :p
