So just to clarify..!Scientist believe they have created absolute zero in the lab, but they also think that?

Question

this 'lab induced' absolute zero, does not exist ANYWHERE in the universe according to the (COBE) Cosmic Background Explorer. ?
Is that correct?

Answer 1

MIT achieved 450 pico Kelvins in the lab. That's .00000000045 K. You can never reach absolute zero. To cool something you must be able to take heat out of the system. That implies something colder than what you want to take heat out of. You cannot go below 0 K so you can't cool to it.

Answer 2

It is unlikely that there is anywhere in the Universe where the naturally-occuring temperature is less than 2.7 Kelvin, because the entire Universe is bathed in the Cosmic Microwave Background Radiation at this temperature.

On the other hand, it is relatively easy to achieve temperatures lower than 2.7 K in the lab.

Various lab experiments have achieved temperatures that are a very small fraction of a degree Kelvin. It is not possible to achieve absolute zero---such a system would need to be perfectly isolated from the outside, and that is not possible.

A few corrections to some of the above answers:

Many materials are not superconducting, even at arbitrarily low temperatures. The superconducting state results from the pairing of conductive electrons---many materials simply do not have conductive electrons to pair.

The Universe will not re-collapse when absolute zero is achieved. Given our current understanding of the Universe, it is unlikely it will ever re-collapse.

Answer 3

I would definitely believe that their is a God. God is the creator of everything. He is the one who created the universe, and he is the one who made this earth livable. I do not believe that the world was created be accident. In Genesis Chapter 1, the Bible describes the creation of the earth. And addressing Ladyren and ^_^'s question about who made God, well, God is timeless. One year can be like ten thousand years to God, and ten thousand years can be one day to God. God is timeless. Rev. 22:13 - I am the Alpha and the Omega, the First and the Last, the Beginning and the End. The answer is simple. God has always existed and will always exist. He was there from the beginning of time.

Answer 4

Absolute zero is like the speed of light, it's a physical limit. It's impossible to get to absolute zero, you can get really, really close, but you'll never get that last billionth, trillionth of a degree.

Answer 5

Yes

Answer 6

well absolute zero means that molecular movement stops! meaning that all materials known to man become super conductors!
absolute zero is imposible to acheive on earth or nowhere else in the universe. the background temperature in the deep universe is 3 degrees kelvin over absolute zero. when absolute zero is acheived somewhere in the universe...universe will contract! (opposite of big bang)

Answer 7

Presently, they might not have found, but it may exist some where, and should be detected in coming years. I am optimistic, similarly the scientists also.

Answer 8

Hmm...I don't know... We've made a bomb ,1 hotter than the sun (Thermonuclear/Fusion Bomb)...Why not to make something colder than everywhere else ..
The absolute zero is exactly -273,15 degrees Celsius ... It's .... cold :-D

Answer 9

yeah but will it keep my spaghetti sauce frozen? haha theres alot of thing in nature that does not exist in labs.. humans have made things in labs for years "hotter than the sun!!" hmmm!! so i guess colder than space is not too different. this is not a egghead answer.. just a regular Joe answer or in this case Lois haha
