US researchers have claimed to perform the coldest chemical reaction by ultracold molecules interaction. Surprisingly, their new instrument slows down the speed of molecules and succeeded in capturing the moment of molecule interaction at an ultracold temperature of 500 nanokelvins. However, the researchers could only able to witness the start of the molecular interactions, which occur in millionths of a billionth of a second. Even the ultrafast lasers of their equipment couldn’t capture the whole interaction. Scientists are now planning to use current observation to more precisely predict what happens during chemical reactions.
