WebbCosmologists have pondered the ultimate fate of the universe, and many have converged on a theory: the “heat death of the universe,” also known as the “Big Freeze.” The Big … WebbIn slow-freezing methods cells are brought into a suitable freezing medium and cooling is continued below the freezing point of the medium. Ice formation does not necessarily start at the freezing point. Small ice crystals have a lower melting/freezing point than “bulk” ice, due to their large surface tension.
