Giant laser heats solid gold to 14 times its melting point

•
00:46 How hot can solid gold get?

A new study suggests that gold can be superheated far beyond its melting point without it becoming a liquid. Using an intense burst from a laser, a team heated a gold foil to 14 times its melting point, far beyond a theoretical limit put forward in previous studies. The team suggest that the speed at which they heated the gold allowed them to shoot past this limit, but there is scepticism about whether the team actually achieved the level of heating they report.
