is there anything in the whole universe that has a temp of absolute 0?

Answer 1

No.

Aside from the fact you need something colder to cool something down (and there is nothing colder than absolute zero), quantum physics says it won't happen. Since temperature is simply a large scale measurement of how much molecules are vibrating or moving, it makes sense that absolute zero is defined as the temperature at which molecules don't move at all. However, it is physically impossible for molecules to be completely motionless because this would mean their position is precisely predictable--this is impossible, according to quantum physics.

In reality, there is a minimum amount of energy that a molecule MUST have, called its zero-point energy. You cannot reduce its energy below this without violating the laws of quantum physics, and thus, you can't lower its temperature to absolute zero.

Answer 2

The lowest temperature anywhere in the natural world, even in the depths of intergalactic space, is the temperature of the microwave background radiation; 2.7K. In the past it was warmer than now. In some laboratories on Earth, temperatures as low as a fraction of a millikelvin above absolute zero have been reached.This is the lowest temperature that has ever been reached in the history of the universe, and it's cold enough for a new form of matter to exist; a Bose-Einstein condensate. An awesome thought.

Answer 3

A black hole has a temp of absolute 0. Unless you believe in Hawking radiation.

Answer 4

not known to us

Theoretically, scientists say it is impossible though.
