CERN is an incredible place. When I worked in Geneva in the 80's, I and my colleagues used to go to their canteen for lunch as it was open to all and we often chatted with all sorts of Nuclear Physicists who told us some about their research and sometimes gave us a tour of the facilities.
In those days they were just building their second particle accelerator which was almost as big as this and also looped underground into Swizterland and back again into France
this stuff amazes me

it confuses me!
I can't comprehend space, the whole thing doesn't seem to equate to me, the cosmos we live in is a certain size, so many billions of years old and it takes 100,000 years for a light beam to transfer from one side of the milky way to the other side, so in essence what they view up the mountains in Hawaii is 100,000 years old, yet it tells us lots about the galaxy we live in, but our galaxy is only of a given size, there are numerous galaxies out there all of their own size, but where does it end? do you literally get to the end of the universe? or does it continue? Einstein said that gravity was a unilateral given element that could be deformed when subjected to forces, gases and planets, now Einstein depicted the gravity ball we all live in as just that a ball, so what's outside the ball? there has to be something, but what!? I still fail to see we are the only intelligible beings that inhabit our said cosmos...
maybe in my lifetime some of the above things will be answered but I hold little faith as we can't travel at any sort of speed, yet the edge of our cosmos is a good few billion light years away.
and don't get me started on black holes, they confuse me ever more, the wormhole they have has to go somewhere!!? WHERE!!?
back on topic!
it's a bloody big place by the looks of it!

its worse than that. the milky way is 100,000 light years across, not 100,00 years
and I do like the question that if the universe is expanding... what is it expanding into?
but yes, its all very mind boggling really, but somehow I can't see why the universe would be as big as it is if there wasn't a way to traverse it easily

At 27 kms in circumference, I can't see anyone installing it into a De Lorean anytime soon.

Well if we were the only beings in the whole universe it would sure be a complete waste of all that space. Lol. Perhaps it is endless we probably are not meant to find out till we die i dont know but there has to be something else out there there cant be just nothing. |

it's a paradox. On the one hand, there can't be nothing, because that would imply that nothing can exist at all. If anything exists at all, even a tiny dot of matter, then it's not possible for there to be "nothing". The existence of anything at all obliterates the possibility of "nothing"
If there is no such thing as "nothing", then "everything" must be infinite, since it is bound by "nothing". If there is no such thing as nothing, and since the universe appears to be finite (though science can only deduce this, it's never been proven), then there must be "something" outside of this universe. What that something is we cannot define as yet (though string theory is giving it a good go).
Is "something" exists at all, where the hell did it come from?? That's the paradox. There can't be nothing, but it's equally absurd to propose that the "something" just happens to be here and has been from and to eternity.
Basically our existence (and self-awareness) proves we do infact exist, but that existence itself has no origin, and is therefore impossible.

arent those long pipes used in terminator 3? haha...
for me its a waste of time. unless they prove that it WILL REALLY WORK the way they want it to work

that's the beauty of quatuum mechanics - things don't always follow the logic of the world as we know it. Something can be in two places at once in the quantuum world.
So nothing can be something, and perhaps quantuum theorists will soon discover the maths that will explain how the multiverse (string theorists believe there is not just one universe but many on different dimensions) can come into existence from "nothing".
I expect things such as "zero point" energy and perpetual motion will be discovered not long after.

@masseur,what the universe is expanding into is still unknown...and neither is it's shape..but it must be remembered that the universe isn't actually the universe..there maybe SOME material or object beyond it..
--I don't have a  and neither do I have a  ..but I doo have a Nokia s40v2! And that makes me proud! |

I guess the point of that question is that the universe is supposed to include everything that exists in time and space and therefore any material that exists outside the universe must, by definition, actually be within the universe.
of course this question is a paradox because if the universe is expanding its logical to conclude that it is expanding into something, but if there is something to expand into then, again by definition, the universe must be including that which it is said to be expanding into
also, I guess it comes down to what the actual definition is for universe if it is not as I said earlier, everything in time and space... is there some border that encompasses it such that everything outside that, and which possibly obeys different laws of physics, is not included?
hmmm...

(yep,but mentally,logically,technically,physically and physiologically,there is a limit..but the universe is far beyond it.There's on one thing between that limit and the country borders of the universe.As the topic says,there is this time machine thing but I think that we may go to the future OR the past..but don't think we will.As the universe is expanding,the thing outside,may,according to my notebook,come inside the universe.{note..please,I'm giving this info but don't use it for any commercial purposes.Also don't copy and paste this.So it's copyrighted until the universe ends by my notebook.}Because of the fact that matter cannot reduce to it's half by pressure,it has to come inside which I think will cause another big bang.COPYRIGHTED.)

I've put my stuff within the quote
Ok..1 minute gone since you started readin this post.Wow!Great speed..not of reading..you've moved 4500miles from where you were last time! Ok..Again I don't have a  and neither do I have a  and neither a pc.But I'm proud of owning a s40v2! |
