Physics is one of the most important sciences. Its purpose is to find out how the universe behaves! Phyisicists through the ages "Newtons" of stuff and now we're sharing these phyisics facts about gravity, force, energy with you.
According to the laws of physics, the lowest possible temperature has been calculated to be a mind-boggling -273.15Â°C. This temperature is known as absolute zero.
