This is wonderful.

what if there is more than one universes like a multiverse?! what then

if there is more thin one universe than it could be possable that our universe would collidi with anouther but Im not sure what exactly would happen in that scenario, either the barriers, or edges of the universes would hit each other or the galaxies in the other universe would come into ours and vise versa, creating a region of space in which you would be in both universes at the same time, hey maybe anouther universe would come to us and we wouldnt have to do anything

When did this turn into soft science fiction?

*reads topic title*

oh

mabe they can morph in one,deflect afther bumping into eatch other,or a big boom

edit:well it came from aliens to universe,well who cares,the two have something incommon and well.... mah who cares lets discuss about this,till somebody doesnt flint another alien idea

maybe, theres no way of knowing untill it happens, if it happens

what a conference
edit:what do you think about alien abductions,are they fake or not.... discuss!

Fake without exception. Back to the topic at hand:

There seems to be a fundamental misunderstanding of the way the universe's expansion works. The universe is not expanding into anything. It is creating the space as it goes. While there may be other universes, there is no "outside" of the universe, because there are no spacial dimensions for an outside to exist in.

The exansion of the universe should slow down because of the effect of the universe's matter's gravity, which as we know is the bending of space, should slow it down, even reverse it. If there is enough matter in the universe we would expect gravity to curve the universe's topology away from flat into itself, creating a curved universe. If we imagine the universe to consist of two-dimensional space we can represent the closed universe as a sphere. As the Senior Wrangler of Unseen University said of the unusually round world Earth in The Science of Discworld, "it's hard to get used to directions here. Wherever you point, it's at the back of your own head." Travelling for a sufficient time in any one direction in a closed universe, allowing for expansion, will lead your back to your starting point.

As it is, it is becoming increasingly unlikely that the universe is closed, but it makes the topology of the universe rather more difficult to describe. In addition, while there appears to be insufficient matter in the universe to account for the gravity we observe (assuming that it is not down to a basic error of observation deep in the calculations), implying that there is a very large amount of unobserved matter in the universe (with the properties of being both cold and dark), the rate of the universe's expansion is not slowing at all, but increasing. We do not as yet know why.

Guess the Universe has already been figured out. Bang. End of discussion.

You can't. If the universe is finite, then they can't possibly reach the barrier. Either they'd be turned around automatically, or (more likely) time would slow to an infinitely low rate the closer you got to the 'edge', such that you'd never actually get to it.

That's one possibility, yes.

Heh. I'll take that.

What, then? If there are other universes, we are not affected by them in any non-quantam way, so it's a moot point.

Not in the slightest. The more we discover, the further the horizons retreat.

maybe, you don't know what you're gibbering on about.

this.

Real Science and loving every moment. ;)

We're on the inside but there is no outside.

One side of my face dropped.

how did scientists figure this out?

that's probably true

thanks for the info

hmm,never saw this,thanks for the info,hm what do you think has a black hole any endings,like it sucks you and throws you out somewhere else(if we ever unlock the technology to iron or a material that could withstand the gravity crush)

Well, energy cannot simply...vanish, neither can matter, it can only be transformed, so there may be entirely new...let me think of a word to cover this...worlds, in a non-planetary sense, that our brains must see to understand, within the holes.

good point, like water, it cant be, you know, destroyed, it can only change state, the amount of water on this earth was the same amount as there was 65 million years ago, its in a cycle.

yeah,did anyone saw that vid that explains how did the ice age started?

meteor, dust, ice, brrr!

they said something to do with co2,while they were drilling on the ice on the tarctic

You tit, of course there's a different amount of water...blasted by comets, creating water from hydrogen plants, chemical reactions, alkenes. You ruined my space vacuum argument, you can never be forgiven.

who me?

Yer you! No, OtitIB

well i was talking about a planet filled with co2

well, i meant that water cant be destroyed, more water can come but i didnt think id point that out as it would just get more complicated and i didnt think any of you knewww....
:fuzsad:

Water sure as hell can be destroyed.

Water is H2O. You can break it down into Hydrogen and Oxygen.

There isn't a set amount of water in the universe.

yes, not destroyed though is it? its components are still hanging about, its not water, but its still there.
