I would have to assume that if there is no "maximum" temp, there is no "minimum" temp.
The minimum temperature in the Universe cannot be zero kelvin any more than the speed of a particle with mass can be c. To get to each of these values would require infinite energy so, no go.
Negative Energy becomes a requirement, looks at it's watch and decides that, once again, it's time to raise it's incomprehensible head above the parapet to check that nobody has spotted it yet:)
QuoteThe minimum temperature in the Universe cannot be zero kelvin any more than the speed of a particle with mass can be c. To get to each of these values would require infinite energy so, no go.0 kelvin, would usually mean NO energy, infinite energy is as far away as you can get from that goal.
What I am curious about is that if gravitons are to exist, how do they escape a BH?
There could be inumerable additional dimensions but I think that the important factor is whether they interact with our ones or not, and to have an effect upon our dimensions they must have some degree of existance within them.
I entered Randall-Sundrum into Google and although I have a vague idea what most physics are about it might as well have been written in Chinese for all I could understand.
I can't help but think of the way that the probability decreases with distance from the strong brane as a gradient, and then we're back to what causes the gradient,
I can't get around the idea that for one thing to affect another, there must be something in common between the two.
i.e. branes dictate the bulk, and if they're intrinsically different from each other, there'll need to be an intrinsic gradient of some sort between them, in the bulk.Interesting:)
Something that occured to me last night, while I walking somewhere, is that if one of the branes was contracted to a point, it's shape would be a simple 5D cone and the change in the 4D cross-section might do nicely for the warp. A truncated cone would work too, without the need to contract to zero and if you need a non-linear warp you could use hyperboloids.
