DOES THE FORCE OF GRAVITY STILL EXIST AT ZERO KELVIN?
Arthur Chayun
There’s no definitive answer to this question, because the laws of physics prevent any system from reaching absolute zero temperature, approximately -273.15 degrees Celsius. But there’s no reason to expect gravity to vanish at that point. On the contrary, its existence is one of the things that makes it impossible to achieve absolute zero. In practice, the force of gravity remains unchanged at the lowest temperatures attained so far, such as those in the International Space Station’s Cold Atom Laboratory, which are just a few trillionths of a degree above absolute zero.
