aman Posted October 19, 2002 Posted October 19, 2002 In intergalactic space, is there a temperature? Where would it come from? Just curious. Just aman
aman Posted October 19, 2002 Author Posted October 19, 2002 Is there any natural space in the universe at 0 deg. Kelvin? Just aman
aman Posted October 20, 2002 Author Posted October 20, 2002 Since indications by experiment are that matter at 0 Degrees K or no energy will collapse on itself into a singularity and Black holes with incredible energy can meet the same definition, then are they close to the same thing but from different directions? Maybe mini-black holes are just really cold. Just aman
aman Posted October 30, 2002 Author Posted October 30, 2002 Would an empty universe have a temperature? Wouldn't it need some energy to maintian its dimensions? I think it would have to be just above 0 kelvin. Just aman
blike Posted October 30, 2002 Posted October 30, 2002 Would an empty universe have a temperature? Wouldn't it need some energy to maintian its dimensions? Great question, I'll see if I can look it up. Wouldn't be able to say off the top of my head.
Ragnarak Posted October 30, 2002 Posted October 30, 2002 Deep space has a temperature of 2.7k i believe, which is, as stated above, due to the cosmic background radiation
fafalone Posted October 30, 2002 Posted October 30, 2002 Isn't "heat" a measure of molecular movement? Or is that "temperature"?
Ragnarak Posted October 30, 2002 Posted October 30, 2002 both? temp is measure of average KE of particles heat is a type of energy related to motion of particles
fafalone Posted October 30, 2002 Posted October 30, 2002 Cosmic background radiation obviously exists, but exists where there are no particles, so how could both only apply to particles?

Heat is a form of energy It can be transmitted through space Waves transfer energy from one point to another I think we may be getting into the territory of wave/particle duality thinking.
Ragnarak Posted October 30, 2002 Posted October 30, 2002 oops forgot to add cosmic background radiation is microwave radiation

That's what I was asking. The difference between heat and temperature.
Ragnarak Posted October 30, 2002 Posted October 30, 2002 Originally posted by fafalone That's what I was asking. The difference between heat and temperature. heat is the transfer of energy due to a change in temperature ie. convection, radiation, etc I think that's the simplest way to look at it. ps. why can't we delete posts? i accidently quoted this one instead of editing it
aman Posted October 30, 2002 Author Posted October 30, 2002 I thought the background radiation came from a hydrogen ion cloud expanding at the edge of our universe. The ions still have the heat of existance and a temperature that keeps them from collapsing into singularities. Is the other side a cold singularity or does it have energy to maintain the 4 dimensions? Just aman
Ozman Posted January 24, 2003 Posted January 24, 2003 If you subscribe to the most popular intrepretation of quantum physics, the number of dimensions and the number of universes is infinite. I say, IF you subscribe.....
fafalone Posted January 24, 2003 Posted January 24, 2003 I subscribe to the quantum physics that leads you to finding that there are 26 dimensions.
JaKiri Posted January 24, 2003 Posted January 24, 2003 Originally posted by fafalone I subscribe to the quantum physics that leads you to finding that there are 26 dimensions. I thought it was 10 nowadays? Assuming we're talking about M-theory here. And don't forget Zero Point Energy, y'all.
fafalone Posted January 24, 2003 Posted January 24, 2003 It depends on how you look at it; as the theory goes it may be possible to simplify, but we're definately not certain yet.

I was under the impression that the microwave background is made of particles. These being the photons that mark the time when the Universe became "transparent" to radiation (apprx. t=300,000 years. if my memory serves). kind regards

KHinfcube22 Posted April 26, 2003 Posted April 26, 2003 wouldn't shooting air into space cause liquid nitrogen and liquid oxegen be formed?
fafalone Posted April 26, 2003 Posted April 26, 2003 No, it would cause gaseous nitrogen and oxygen to form since the molecules will spread out as far as possible.
