Entropy says that there is a constant diminution of heat (relevantly) toward equilibrium in isolated systems. If the universe is in fact cyclical or flowering it may be that no iteration is truly isolated. If so, entropy would not universally apply and the cosmos itself might be a legitimate perpetual motion machine.
This is pure speculation of course but it gives us idea-parameters.
The problem for the big-crunch idea with the recently detected accelerating expansion is that right now nothing known could reverse the process. Because of this, the big crunch is virtually a religious idea (at least for the time being) because it requires an appeal to something utterly unknown to keep it. _________________ K Michau

Given current knowledge, it would have already started. And this is what they expected to see, that the acceleration was slowing down, a decrease in the increase as it were. But what they actually found was an increase in the increase. Whatever is doing that would have to weaken or stop for gravity to take over.

I agre with you.
but one question is there anyproof of dark matter? or dark enegry? _________________ "If people are good only because they fear punishment, and hope for a reward, then we are a sorry lot indeed." Albert Einstein

The accelerating expansion of the universe is the evidence. As I understand it, dark energy is just the name they've given to whatever mysterious force is causing this, without actually understanding what it is yet. Same deal for dark matter--they are both just the names given to the mysteries behind the anomalous observations. There are theories as to what they are, but nobody really knows yet. _________________ Cectic - My semi-weekly skeptical webcomic. |

Its been detected. Its been on CNN.

Dark matter may or may not be related to dark energy depending on the theory, but both are simply names for the unknown thing that would have to fill the hole that is responsible for observational results.
The case for dark matter is much firmer than for dark energy. Dark matter was postulated early on to explain the whirlpool behavior of galaxies. Assuming no dark matter, the rotation speeds did not add up. So it seems pretty sure that there is dark matter, but whether it's mini black holes or WIMPs or MACHOs or non-radiating normal matter or some combination is unknown.
Dark energy is the name given to whatever is driving the continued acceleration of universal expansion. This could be all sorts of things, including a resurrection of Einstein's "biggest mistake" of the cosmological constant. An interesting thing about dark energy is that it may not be real, that is it may be a not-well-understood effect of processes already known, whereas the case for dark matter is very strong and it appears there is LOTS of matter out there we can't see. _________________ K Michau

Wikipedia talks about Alternative explanations how popular are they? I watched a show about darkmatter and the person that found stars stying the same speed said that it could be gravity laws not understand yet. _________________ "If people are good only because they fear punishment, and hope for a reward, then we are a sorry lot indeed."

that could just be the nature of spacetime and nit be connected to dark matter. _________________ "If people are good only because they fear punishment, and hope for a reward, then we are a sorry lot indeed." Albert Einstein

It's possible, but it's usually better to give more credence to the simpler theories that fit the evidence without rewriting large portions of already established science when investigating new phenomena (Occam's razor). _________________ Cectic - My semi-weekly skeptical webcomic. |

I know about occam razor and i was using it to just cut dark matter out.
I think it still needs more proo, but I'm not closed to the idea. _________________ "If people are good only because they fear punishment, and hope for a reward, then we are a sorry lot indeed." Albert Einstein

It's an interesting time for cosmology. A number of things taken as common knowledge for years have been turned on their heads recently. The feeling I have is that cosmologists and physicists are scrambling for coherence.
My grandparents have about 30 years of Year Books. Once I was looking through the one for the year I was born (1964) and ran across the entry for the recently-discovered Quasar. It was interesting to read early ideas of what they might be. All of them were WAY off by modern standards, placing them nearby or even inside the Milky Way. There was no mention of spectroscopic analysis showing that they were extremely far away and therefore extremely bright.
Ever since then, I'm very dubious when I see speculations about what newly discovered phenomena might be.
A case in point is massive gamma ray bursts. At first some scientists thought Einstein was broken because the bursts were just not possible under relativity. To produce the energy involved, some speculated about self-annihilating collisions of matter and anti-matter neutron stars. I believe it was Martin Rees who suggested that the bursts are emissions from quasars with a pole that just so happens to be pointing at us, saving relativity. _________________ K Michau

Hell, just a few years ago at about 1999-2000 they still didn't have much of a clue of what a gamma-ray burst was. i read some pretty strange theories about them around then.
One theory was that they were the energy bleedthrough of a collapsing universe that was next to our own. O_o _________________ -=The Believer is Happy; the Skeptic is Wise=-

The one I think is most appected is star becoming black hole and the gamma ray burest are from there poles. _________________ "If people are good only because they fear punishment, and hope for a reward, then we are a sorry lot indeed." Albert Einstein
