What's The Coldest Temperature That Could Ever Exist In The Universe Thank You?..?

Absolute zero, minus 273.15 degrees Celsius.

zero kelvin! but temperature can never reach it

ABSOLUTE ZERO

- 273 Celcius

The temperature at which every element known is frozen .. so it can't get colder.

Absolute zero. 0K or -273.15C

temperatures below zero Kelvin are theoretical

It is not theory, but the Temperature that Hydrogen freezes

-273 Celcius or 0 Kelvin

Barely above absolute zero, 0°K. Like 0.00000000000001° K, you could have as many zeros in there as you want, but can you measure that precisely?

Slightly above absolute zero.

The temperature now is 2.8 Kelvin

In 14 billion years it will have fallen to 1.4 K

28 billion years after that 0.7K

56 billion years after that 0.35 K

etc etc

The temperature will approach 0 K but will never reach it.

Theoretically, Absolute Zero is... But, here's an article claiming they made atoms get *colder* than Absolute Zero:

absolute zero. At that point all molecular motion stops

There is no way to really know because there is no one there to measure it!
