Could the universe ever reach an even temp of absolute zero ? If so what would happen ?

Answer 1

Absolute zero is impossible to reach. Here's why:

To cool something, you need to draw heat away from it. This means you need to touch it to something that is colder than it, because heat always flows from a hotter object into a colder object when they touch. To lower an object to absolute zero, you would need to place it in contact with something whose temperature was LESS than absolute zero, and this does not exist.

Answer 2

As long as there's matter in the universe, it could never reach absolute zero for there would be too many frictions between atoms and molecules. Remember that temperature is the motion of particles in matter. If there's matter, there will be friction and when there's friction and movement, absolute zero is impossible to achieve. If we do reach absolute zero, then everything will freeze (DUH!). When it's absolute zero, all the motions of particles in that matter will stop. Unless it's at zero, all particles in matter move around. The more heat, the more it vibrates and the less heat, the less movement it has but unless it's absolute zero, there will always be motion.

Answer 3

Theoretically, when the time=infinity happens, you'd reach absolute zero. The universe cools a little bit each day, but, like always dividing the distance you are to the wall by 2, you get very, very, very close - but never actually get there.

Answer 4

As cosmological expansion accelerates the universe will asymptotically cool towards absolute zero but it will never actually reach it. Eventually the temperature of the universe will descend to the Gibbons-Hawking temperature of the vacuum due to virtual pair creation, but not absolute zero.

Answer 5

I don't think so unless somehow it spread so far that every molecule of anything was far enough from every other molecule of anything that they wouldn't affect each other.. but will that happen? Doubt it, too much movement and attraction in the universe.

Answer 6

Only a very cold solid could be seen. So no chance of existence of life

Answer 7

oh dear, absolute zero. using 'the ideal gas law' of PV=nRT the universe keeps on expanding or contracting, how does it truly matter?

Answer 8

All activity in the universe would cease, there would be no events taking place there would be no no time.

Answer 9

As long as you keep on halving something, you'll never arrive at Zero. ~

Answer 10

No, impossible. to do that you'd need to remove all the stars and planets!
