/agrees with Heltak

Somthin like a fifth of all stars become black holes and stay that way forever. That would seem to say that everything eventualy will be part of a black hole.

The thing is they emit x-rays and all sorts of other stuff. If the intense conditions in the hole are transforming matter into energy (theoreticly possible. 3 grams of matter would power a 100watt lightbulb for over 85000 years!) that "matter" is in face leaving and there is hope for the universe

Ok, now whos going to make a graphic of it and put it in a mod?

The other side of the coin is dark energy, like Esq. mentioned. You would think that black holes ultimately would swallow up everything. Assuming a fairly static universe, this could be the case.

But astronomers have been observing that rather than slowing down or contracting, the universe that we can see and measure is expanding. Galaxies are flying away from each other, not toward.

Dark energy is believed to be the "propellant" so to speak. It is believed that there is lots of it and that it is pushing us all out so that, now, some theorists think that our universe ultimately may be ripped apart by what seems to be the unstoppable expansion.

But how is it hat "Dark" matter can exist with "Light" Matter without ripping each other apart from the differences in each of them? Surely this must mean we have a third "Grey" Matter?

@Hel

I'm not well versed enough to explain. Also, it is supposed to be "dark energy" as opposed to dark matter as I posted earlier.

Am now going back to correct that as well. Sorry about that. Look here.

Woah heavy. Imagine if that did happen, that would be the SCARIEST thing ever. The planets disappearing would cause 3 months of complete anarchy fro mfear etc

Dark matter (or energy which is the modern moniker) does not have the same relationship with normal matter that matter and anti-matter do. That is to say that they do not react with each other in a "physcial" sense, although the forces that they possess do.

As for the universe ripping apart, I prefer the other theory; that there will be a big contraction when the universe stops expanding, and everything will begin to be drawn together again. The interesting thing about this is tht time will begin to run backwards as well.

Steel - That's one I haven't heard. How the hell can a singularity move? Kimk? Anyone?

Esquilax, so Hitler becomes a hero and Neil Armstorngs the last man off the moon? And St Francis of Assiss cuts up small creatures etc

And we al;l go through puberty... BACKWARDS

Why would everything run backwards?

And while I like the concept of everything expanding for a while but eventualy drawing back together, there is for example an escape velocity from solar orbit. Voyeger achieved it... at it's speed, it won't start falling back for an infinite amount of time, although it will go increasingly slower. Perhaps the galaxies are moving at the escape velocity of the universe?

WB - As I understand it, because time and space are the same thing, when the universe achieves a certain critical size, internal forces would force it to retract. Now because "space" itself is shrinking, time is also running in reverse. I'm a bit rusty, so I may not have explained that correctly.

As for your "escape velocity" theory, I suppose that it is possible, however I doubt it. Allow me to offer the fololwing example. Imagine that the earth were expanding, and that the continents were galaxies. Now when then earth reaches a critical size, and begins to contract, the continents would be moving at the same rate as the planet, and thus, could not achieve such a velocity, but would follow the earth in its contraction. That's my theory.

Well, expanding of universe can mean one thing...the BIG BANG!!

Here is the theory of big bang I read in Discovery:

As we all know there are parallel universes. We can not see them but they are there. Now next to our universe is parallel universe, in which as in ours galaxies are moving further apart. As galaxies move apart, the 2 universes attract each other, until the point where they will meet at one point, because such enormous force will be created (big bang), both universes will be incinerated and everything will start over. At first dust, that will attract and become dense to create planets, starts and other space bodies. Galaxies will again move apart to point where parallel universes will collide, and everything destroyed again. This is an endless cycle, that destroys and creates.

@Esq

I think the theory about the universe eventually collapsing has been shelved.

so what shall we call the big open space that holds these so called "parallel universes"?


this is my world; it goes round and round and round

Dont know to tell you the truth. In discovery it said someting like they are less than millimeter apart , or something like that...but it is weird. I will try to find article on internet, or if not scan it and post the pages . It is interesting stuff, but kind of weird
