Paul & rich I appreciate your comments. It's obviously very complex. Clearly a new Einstein is necesary to resolve physics most fundamental problems. It's hard for an uneducated person like myself to accept that relativity and quantum physics are incompatable. Only a true genius could pull these two concepts together and explain how it works or more importantly why it works.
I'm thinking now that a curved universe, in theory, could wrap on itself. I guess I'm saying that if you travel far enough in one direction you could find yourself where you started. In a flat universe this is simply not possible. I suppose that just because we perceive the universe as three-dimensional doesn't mean it actually is. I suppose it could have as many dimensions as it needs. When I imagine the universe in "the bulk" or "hyperspace" with other universes I think of it being egg shaped, maybe this is way off. Maybe if you could perceive it it would appear flat in relation to the other universes. Maybe it wouldn't be something you can even visualize.
Think of the universe as a 2x4 board. It's three dimensionaland yet if it's a good and true board it hasn't got a curve or warping. Hence it's three dimensional yet it's straight on it's plane.
What intrigues me is weather there is life on the planets in the solar System, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Certainly the conditions on most other planets make this very unlikely. Their temperatures, for example, are too extreme, fluctuating from severe cold to searing heat, for the plant and animal life of Earth. Also Mercury has no Atmosphere.
Your weather expression is kind of funny if you meant : whether the wheather conditions are appropriate for life in our solar system, not the solar system as there are many in the universe. Our galaxy is the Milky Way and the for the probability of life in the Universe, I suggest you read the following link by Stephen Hawking we all know who he is:

But we only know one.
Actually, the Solar system is the system of planets and other objects that orbit around the star known as "Sol," which is our own. Also, we do know of over a hundred extra-solar planets, mostly from their effect on the motion of their parent stars. However, we have recently directly imaged a Jupiter-like planet orbiting around the star Fomalhout, so we do know of planetary systems orbiting other stars, but they shouldn't be called "solar" systems.
who knows if there is actually a end in the universe. Isn't it infinitive?
The universe is not infinite, despite what my icon says (nor is it an infinitive, but that's besides the point). If it were, night wouldn't exist. See Olbers' Paradox. No, the universe is finite in size and has a finite history. The question regarding the flat-ness of the universe is one of whether the future of the universe will be finite. Personally, I find the idea of a flat universe to be inelegant, and much prefer a spherical curvature. Unfortunately, recent evidence is against me on this matter.
Just read some of the earlier post I made, and others.
They apparently found H2O on Mars which means that there is most definately some life in it's past. Whether or not there is will tell us that life on other planets is not only possible but likely. It's important to keep in mind that although our universe is not infinite it's rediculously huge. If there's life on Mars it's likely that life is everywhere in our universe. If there is water but no life then it's much more questionable.
As for the infinity question. It's highly possible that there are other "Universes" which could exist in 4 different forms (called levels). The Multi-verse which contains these "Universes" would very probably be infinite. Keep in mind that there is no evidence that any other universe exists; this is mere speculation. Also keep in mind that I don't really know anything.
I think the future of this universe is finite. It's also important to note that a universe that is a hypersphere is definately finite because it's contained. This may be obvious to some but it's hard to put together.
We only know what one?
I think he meant one solar system.
What do you think he meant and what he meant to say and what he is thinking about the solar system? About and what he is about to say are all different opinions on the subject. Can any english person say as good as a french person what they mean ?
And what is the one solar system mean, I have absolutely no clue!!
Wow I didn't mean to offend. I'm pretty sure being French has nothing to do with it. Our solar system is the solar system. Other planetary systems are just that, "planetary systems." Sol is our star. There was a time when we didn't know if other stars even had planets. We know now that they do. We cannot see these planets but we can locate the really really big ones by the ways in which they affect their stars.
We only have one solar system.
so much of this theory is more like science fiction than science :*( Scientists have yet to really prove most of these hypotheses. I heard some of the math is quite faulty.
WOW this is way to deep for a Saturday morning.
I have two questions and they are:
1. If it does end the universe that is then what is on the other side?
2. Of all the possible planets that are out there do you think they play chess?
Planets don't play chess! They have no hands to lift the pieces. Silly!
They might be able to move the pieces with there brain !
assuming (you know what that means), that planets have "brains"....
Pluto vs Saturn !
