(Phys.org)—There are many experiments that physicists would like to perform on antimatter,from studying its properties with spectroscopic measurements to testing how it interacts with gravity. But in order to perform these experiments, scientists first need some antimatter. Of course, or they won't be finding any in nature (due to antimatter's tendency to annihilate in a burst of energy when it comes in contact with ordinary matter),and creating it in the lab has proven to be very technically challenging for the same reasons.
