Predicted to exist at pressures above roughly 400 GPa, and probably present inside Jupiter. A 2017 claim of observation was not reproduced. Experiments at the limits of diamond anvils continue, and the reading of their optical and electrical data is disputed.
Posed 1935, Eugene Wigner and Hillard Bell Huntington.
