Why don’t the physicists want to recognize a important simple fact?

Question

==========
Everyone knows, that absolute temperature T=0K
cannot be reached. But is it enough reason to think
that space T=0K doesn’t exist?
The birds communicate with songs.
If I cannot understand songs of birds does it mean
that they cannot exchange information with songs?

Answer 1

The problem you're running into here is that the mathematical models we use to figure out science problems do not represent what happens in nature quite as perfectly as we'd wish. We can extend the line of the graph of the temperature vs. volume graph until it crosses zero at -273.something C and declare that to be absolute zero, where molecular motion ceases. But we've also discovered that due to quantum effects, I think, that there isn't any point at which molecular motion ceases.

This is the sort of thing you have to live with, and the endless arguments it engenders is why I like engineering a lot better than physics.

I'm pretty sure that birds do communicate with songs. What they communicate might not be all that profound, but it's fine if you're a bird. They are practical creatures, more concerned with the status of the worms in our garden than whether we're allowed to think about a state where molecular motion ceases.

Answer 2

This is the way it was exsplained to me: Absolute Zero is not a naturally occurring phenomenon. Even in the vastness of deep space there are too many waves and particles colliding for the temperature to be that low. That being said... The universe is too vast for us to know what's occurring everywhere, so that's just an informed supposition.

I understand that it's possible to *approach* Absolute Zero under laboratory conditions. I've never met anyone who said that it can't happen, only that our current understanding of the universe makes it unlikely.

Answer 3

At T = 0K, all the available energy has been removed from an object. The object can not give up any more infrared photons to the surroundings and the vibrations of atoms and molecules are at a minimum and steady state. To remove more energy it would have to flow to a colder object (below 0K) but nothing is colder by definition. You can not empty an empty bucket.

Answer 4

Show us "Everyone"s credentials to be able to make that statement as a fact.

Answer 5

If it cannot be reached, how can it "exist"? That is an oxymoron.
