is it true that no were in the universe we've found absolute zero?

Absoultue zero in terms of Kelvin is impossible to obtain because there can never be nothing

No! Even without virtual particles, most of which self-annihilate almost immediately, the overall density of 'empty space' in the universe has been calculated to be about 2.11^ minus 29 kg/cubic meter.

To quote dilbert: "Early Civilisations never had a concept of zero" (hey, you wanted it thorough right?) And they started the number system at one. .... Hmm, pretty much the panel cuts out... \nRemember, the ones and zeros are really the positive and negative polaritys on a magnetic disk. That is the key to your computer informations. Do not take a magnet to your computer.

No. Absolute Zero is 459 degrees below zero Fahrenheit. \n\nTemperature is dependent on the rate of oscillation in molecules. At Absolute Zero the oscillations are as low as they can get.

There is a very basic problem here. If you do a computation of the energy associated with the virtual particles, you get way, way, WAY more than enough to produce a closed universe. By one estimate, the answer is *at least* 63 orders of magnitude off. This is one of the worst predictions ever made! Clearly something is going on and nobody seems to have a good idea about how to get plausible results from this type of calculation. A *lot* of cancellation has to occur.

Current information is insufficient to give a correct answer. Once we explore more of the universe, maybe we could have a logical answer.\nst

zero, the earth isn't that old

Nope, 0/0 could be 1 but it could also be anything else.   Division is the opposite of multiplication and 0 times anything at all, even infinity, is still zero.

I doubt that there is life there or elsewhere in the universe. Yes there is ice in outer space and probably on portions of planets which means there probably was water out there at one time. However there are too many variables missing for there to be life as we know it. Believing that there are physical life forms other than as we have here on Earth is just speculation. The more space is explored, the more we know that Earth is uniquely made. If you get a chance see the dvd, "The Privileged Planet".

When there was nothing there was probably no light. My favourite theory (because I can undestand it) is that "nothing" is actually a "quantum foam" of matter and anti-matter popping in and out of existence continually. So 0=+1-1. There is experimental evidence for the existence of this quantum foam. Before the big bang the universe would have been an infinite "nothing" of quantum foam. However, each of these tiny matter/anti-matter formation/anihilation events would produce a tiny gravitational wave. Over (infinite) time these gravitational waves could grow by constructive interference until a huge gravitational wave (rather like the occasional huge freak waves in our oceans) produced the special conditions required to trigger the big bang and caused a huge separation of matter and anti-matter. So the "spark" was simply a result of random noise eventually building to the point to set things off.\n\nI have a personal theory that the "virtual" gravity caused by the quantum foam might explain the missing dark matter and/or dark energy in our universe.

does the universe end?  no one knows yet.  the beginning of the universe is much better understood.\n\nhttp://en.wikipedia.org/wiki/Ultimate_fate_of_the_universe

There is no proof that our universe is, was or will be the only universe.  The nature of reality is that we can only study and observe what is in our universe, so we will never know because there is no way to find out.

In fact, there is a great deal of evidence showing it is not. What little we know of the dark matter and energy is that they are not composed of baryons. But anti-protons *are* bosons. There are some candidates for the dark matter (axions are a good bet) but anti-matter in the usual sense is ruled out by observation.

The universe is everything that exists.  The opposite would be everything that doens't exist.  So, the opposite is nothing.
