What is the definition of Temperature?

How is it measured?

What is the temperature of a vacuum? Does it make sense?

-

At other extremes plasma, such as for a star? A pulsar or a black hole, the Big-Bang?

The Kelvin is a base unit of the SI system. I ask these questions because I don't know the answers and they are of crucial importance.

if heat is osscillation of the molecules of matter, then it isn't present in a vacuum is it, but if any matter were to enter it would immediately be affected by radiation enetering to reach a temperature?

Extreme temperatures may be beyond our comprehension, surely? If by 'big bang' you mean when God created and spread out the stars, I don't see the connection really with temperature. The concepts of an original big bang without divine direction and input has been rocked and shaken I think! And would not be expected to achieve order. Rhiannon

Thanks Rhiannon clearly you thought about it I was expecting something very predictable from readers. Most people would list bodies and quote data from books and giving the "temperatures". Really that is very superficial it goes much deeper. I am pleased with your comment. Saturday is country music!

See you! Tom

Answers to those questions will be readily available via Google. I imagine you are looking for a more philosophical answer. I would be interested in your own take on these questions, Tom. I bet they will make interesting reading. Take care of yourself. Paul

I didn't know you were religious? I do not know the answers.

Cheers Paul, well thanks!
