What is absolute zero temperature ?

I want to know about concept of absolute zero.

Other Answers:

Zero Kelvin, or approximately -273.15 Celsius (?459.67 Fahrenheit). At absolute zero, all nuclear motion stops. Fortunately, this is a theoretical impossibility: the coldest parts of space are believed to only reach three Kelvin, or approximately -270.15 Celsius.
