# How could you produce large quantities of metallic hydrogen?

Could you somehow crush hydrogen atoms with magnetic fields in order to produce it? Or maybe someday someone will invent a material capable of withstanding 500GPa and we'll have giant machines that crush atoms together? Given that diamonds can be synthesized as well I don't think it would be too hard.
