Solar System of Universes

[Tarantism]

one thing you guys: you seem to be establishing a spherical universe, or at least one that has a beginning and an end. this may not be so...perhaps our universe is infinate?

its just a possibility that can be considered.

[ryan2006]

I am saying that our universe is in fact infinite but their are bounded universes. I was once asked to define universe. Universe means one made out of one. Multi universe means there are many universes but allows infinite to remain and that is my stance

[Tarantism]

yeah sorry i was simply posing the question because i was curious as to weather there was any speculation towards weather or not the universe is infinate, or if we can fathom a beginning or an end. thanks for the response!

The only thing I know is that I don't know,
...but I'm not even sure about that.

Oops. That'd be better for the 'Quotes' thread, eh?

[Tarantism]

i dont know anything at all.

but i want to understand things that nobody seems to. this may not be a good thing...

If Cosmic background radiation is the cooling of the universe then where is the heat going? It can't just disappear can it?

I am pretty sure that cosmic backround radiation is not what is cooling the universe. We can, however, look at the changes in CBR over time as a measure of the cooling. The heat definitely does not disappear (conservation of energy), it does, however, change forms.

[ryan2006]

The heat is escaping our known space then, correct? If this is the way it is then heat expands when the edges of Cosmic Back Ground Radiation indicate the early universe is cooling. At the rate of cooling our universe will be pretty cold in about 15 billion years from now. Where will the heat go if heat rises? If heat has every direction to go then there will be a heat up of the edges of the universe. Unless unless it is trapped in a bounded universe.

Not sure if this is relevant but just wanted to add something:

It is possible for a universe to be infinite and bounded, if one considers non-Euclidean geometry.

With regards to bouncing light beams back at the "ends" of the universe, I have come across an interesting idea somewhere which is also related to my previous statement. If you were to fire a light beam into space in some direction, assuming that it doesn't come across any obstacles, then after a while, it will hit you in the back.

Based on my flawed understanding of Thermodynamics, there is no such thing as "heat content". So when we say the universe is cooling, it may be that energy is converted to something else, perhaps matter. My understanding of this is not very clear, so I apologize if I'm incorrect. All I remember from my foray into the subject is that there was something tricky about heat and temperature that went against intuition.
