German researchers approach absolute zero
Physicists at the University of Bremen, Germany have produced the lowest temperature ever recorded, at 38 picoKelvin, which is 38 trillionths of a degree above absolute zero.
Absolute zero is measured as -273.15 °C and it is the lowest possible temperature on the thermodynamic scale. It is impossible for an object to truly reach this temperature because there would have to be zero atomic motion or kinetic energy i...
