How's THAT for a long reply?
Quite nice, IMHO.
for any set quantity of mass, as you decrease volume, temperature will increase, not decrease.
Dip a balloon in liquid nitrogen. You will notice it shrinks as it gets colder. Dip a balloon in a pot of water and heat it up. The balloon will expand as it gets hotter.
I don't know if any of you caught that show on absolute zero that nova aired a while back, but it talked about the first time people turned hydrogen (and helium) into a liquid. It also talked about how they got their ideas off of how someone (forgot his name) turned other gases into liquids. That person exerted great pressure onto a gas (IE decreased its volume) to the point where it liquefied. Also, by liquefied, it actually was colder. It didn't suddenly spring back into a gas when he released the pressure.
Matter doesn't have to "disappear" or be destroyed to reach absolute zero, as I understand it. Neither does the volume need to approach zero
I did an experiment on Charles Law. If you extend the sections of the graph (I did three), they all meet at 0 volume, 0 kelvin.
En.wiki sums it up the best with (Charles Law):
Therefore, as temperature increases, the volume of the gas increases.
Theoretically as a gas reaches absolute zero the volume will also reach a point of zero.
Notice the gas part. If the fact that it is gas screws up everything, let me know. I don't see how it could, however, as every element has the potential to become a gas at a certain temperature. (Especially since everything used and tested with Charles Law becomes a liquid/solid as it goes down the scale.
If you go way back, the Universe was so hot, small, and dense that normal matter the way we recognize it didn't exist - matter took the form of a quark-gluon plasma, basically an incredibly dense soup of particles so hot that they can't even form into neutrons, protons, or electrons.
What about Bose-Einstein condensate? (That word took a very, very long time to find, so appreciate it. I hate knowing what it is but not its name...) Roughly, it is a state of matter "a large fraction of the atoms collapse into the lowest quantum state of the external potential, at which point quantum effects become apparent on a macroscopic scale." It is found at impossibly low temperatures, but it has been achieved.
As for your definition of the Big Bang, it makes a lot more sense than a little explosive dot, but at the same time it makes less sense. Maybe my thinking is too narrow, but I can't comprehend how, why, or
if space is expanding. My thinking is, if you were to go in some zippy little spaceship that could travel faster than the rate of 'expansion', you would
never reach an end of space.
We are just experiencing the shape of the Universe as we move through the dimension of time.
Can you elaborate on this please?
Thanks for the reply.
