Did anyone else see this?  Pretty interesting read..

[ozman]

it sounds like a contradiction in terms but scientists have reached temperatures that go beyond absolute zero in a lab, and get hotter as they do so.
Whereas we’re all aware of what happens when temperatures hit negative temperatures on the Fahrenheit and Celsius scales (hint: it gets really cold), the Kelvin scale is an absolute temperature scale in physics where it is not possible to go beyond 0 degrees Kelvin. Therefore, the lowest point that any temperature can reach is 0 K or −460 °F (−273.15 °C); at least that’s what scientists thought until till now.

Was just reading about this. Very weird. Look forward to reading more about it in years to come.

Wouldn't the use of magnetic fields and lasers as observational tools  impart a small amount of energy  to the observed atoms effecting the results ?

[keninsc]

Ok, so now they have to change what absolute zero is........however, when it's cold enough that all molecular movement stops, that's pretty cold......and they saying they have some thing colder? How did they measure it......if nothing moves, not even atoms.....how do you measure it? Seriously.

[Merc14]

Good question.

[KainFall]

WoW, A medium iv never heard of.. Something that is soo... COLD that it stops moving. and now.. A point that is apparently. MORE COLD, than that.. HAve you ever heard of Cold fire? or hot ice?? Crazy theorys..

Question.. does anyone realize world Phenomena.

I believe they measure with equations, In science lot of things can be measured with equations.

Then they are doing it wrong. Math =/= reality.

And there is no such thing called no movement. When an object seems to be immobile, it could be in movement compare to other objects.

I can go one better than that lol.

When asked for an example of the smallest amount of energy or mass possible people usually state the vaccum of space but they are wrong. I shall use the ocean to demonstrate why. When people talk about sea level they forget the sea isnt flat because its surface has waves which oscillate. The vaccum of space does the same and oscillates around zero energy and zero mass.

You can collect the bits of energy that are below zero and its an exotic form of energy called negative energy. Due to the way in which waves behave all you need to do to turn it into a viable energy source is have two mirrors facing each other in a vaccum. The negative energy attracts the mirrors together.

The energy particles resulting from this small amount of exotic energy are like photons but called ghost particles. Anyway you can produce an exotic negative energy laser beam using them which instead of burning a whole through an object freezes it and drains its energy away. That includes going below absolute zero.

Exotic negative energy violates entropy, the energy is demonstrated to exist in the laboratory and its possible to create a system where the negative energy increases over time paving the way for a perpeptual motion machine.

They supposedly took the sample atoms to within billionths of a degree of absolute zero, and tried various experiments on them. At one point the atoms started putting out energy, rather then absorbing energy. So the idea is that atoms near absolute zero only absorb energy, and can not put out energy. So they think they flipped somehow into a colder state where the atoms continue to move, and start putting out energy.

No they actually did this experiment and these are their actual results.

It is all in the article if you just read it. Some of it is heavy going, but most is not to bad.

Absolute Zero is still the lowest energy-state of matter.  Yes, there are negative Kelvin, but as you decrease negatively, their energy increases.

They are saying it's colder, yet infinitely hotter, simultaneously, due to the properties it demonstrates.  Colder, because it's below Absolute Zero.  Hotter because a -100°K object will give energy to a 100°K object.

They measure it's movement, but I don't know what instrument they use.

Never heard of this before.  Thank you, I'll have to look into it.  Sounds like something from a comic strip... robbing energy from an object...

Question on this, as you seem to know about it... if you do this to an object, for standard's sake, say a gold bar....  Steal the energy, reduce it's temperature to Absolute Zero... When it heats back up, does it's energy return, or does the object decay?

Ok, I didn't read the article just scanned it quickly. I'll have to go back and read it more thoroughly.

I do know that the Speed of Light changes, not that the speed of light actually changes but they can measure it more accurately. To the average Joe, it doesn't amount to a pee hole in the snow but it matters to high end energy physics calculations. I'm assuming the "new" absolute zero is the same sort of thing.
