Does absolute zero exist anywhere?

Answer 1

It won't exist in the universe because of background radiation. Labs can get very close (billionth of a degree off, like someone mentioned). While that is statistically zero, it is not possible to actually reach zero.

To reach absolute zero, all motion in all particles would have to cease completely. If this were to happen, you could know the location and the momentum of electrons, and that would violate the Uncertainty Principle that applies in Quantum Mechanics. There will always be something called 'zero point energy' in a particle, and therefore, even if you get extremely close, you will never actually reached perfect absolut zero.

However, there is another piece of quantum mechanics that could help you out. The strange laws of quantum mechanics dictate that there are certain things the universe cannot recognize. For example, a particle and an antiparticle can pop into existence, annihilate each other and pop out of existence, without violating any laws, IFF the entire process happens in less than 10 ^ -42 seconds. That is Planck time. So maybe there is a temperature that we can reach that is effectively absolute zero in the balance book of the universe.

Answer 2

A group of physicists in Canberra, Australia have managed to achieve 100 billionths of a degree above absolute zero, which is -273 degrees below zero Celsius. There is nowhere in the universe that absolute zero exists that we know of.

Answer 3

Absolute zero used to be a theoretical limit since the only way to make something cold was to bring it in contact with something colder. However, absolute zero was reached by using sound waves at just the right frequency to stop the last bit of molecular motion.

Answer 4

No. The lowest temperature anywhere is the background radiation at the edge of the universe. That's about 4 degrees on some special scale that I can't quite recall at the moment. Could be Kelvin...

OTOH, scientists have been getting close. Google it for a definitive answer.

Answer 5

As of February 2003, the Boomerang Nebula with a temperature of 1.15 K, is the coldest place known outside a laboratory.The Nabula is 5000 light years from the earth and is in constellation centaurus.

Answer 6

Nope. The cold of space is about 3K and in the lab the have gotten within a few billionths of a degree above 0K.

Answer 7

warmth is a spread of ability and is concerning temperature interior the following way (E is proportional to T), E 0< T, E = kT . E is in Joules & T is in ranges Kelvin; ok is termed the Boltzman's consistent that arises using gadgets equipment we chosen. if T = 0, E = 0 of route. Temperature is the degree of the kinetic ability of the molecules that vibrate. If their action ceases and that all of them come to absolute 0, it ability that they do no longer have any (0) kinetic ability. Radiation falling on a substance if it imparts its ability to (or absorbed with the aid of) it, will strengthen the circulate of the molecules of that substance increasing their kinetic ability.

Answer 8

No. They can't even achieve it in the lab. The coldest it gets in space is 2.7°K due to background microwave radiation left over from the big bang.

Answer 9

yes, my interest level in the answer to your question!! ha! Just kidding.

Answer 10

only in youre mind
