Think of the coldest you have ever been. Not very cold unless you have been in an Antarctic Winter or Space without a thermal suit on. Now multipy that coldness by at least 10, for most of you. Now you're getting warm, that is how cold absolute zero is.

Absolute zero is a term used in science to define a point at which all gaseous matter freezes. That temperature by the way is -273 degrees Celcius or zero degrees Kelvin. For it was Sir¹ William Thompson Kelvin (1824-1907)who worked out this point that is so important for the survivial of anything. He was an Irish physicist.

Whereas Anders Celcius decided the point at which water froze was the ideal base for his scale of temperature. Kelvin it was that decided on the Centigrade scale but that the starting point should be the point at which it was impossible to be colder. Thus absulute zero is 373 degrees away from boiling it's top, that is if it is H2O².
