Why Metallic Hydrogen Is the Holy Grail of High Pressure Physics

Posted by in categories: alien life, nuclear energy, physics

Making hydrogen a metal takes lot of pressure. But after a group of scientist’s lost the world’s first sample, the pressure is really on.

Settling Arguments About Hydrogen With 168 Giant Lasers
“With gentle pulses from gigantic lasers, scientists at Lawrence Livermore National Laboratory in California transformed hydrogen into droplets of shiny liquid metal. Their research, reported on Thursday in the journal Science, could improve understanding of giant gas planets like Jupiter and Saturn whose interiors are believed to be awash with liquid metallic hydrogen.”

What in the World Is Metallic Hydrogen?
“On Earth, as we’ve seen, hydrogen’s behavior is straightforward. But Jupiter isn’’t Earth, and the hydrogen found in abundance within and beneath the great bands and swirling storms of its atmosphere can be pushed beyond its normal limits.”

Insulator-metal transition in dense fluid deuterium
“The conditions in which hydrogen disassociates and becomes an atomic metal occur in high-energy-density environments, such as the interiors of giant planets and nuclear explosions. Celliers et al. trained 168 lasers on deuterium samples at the National Ignition Facility to measure the pressure and temperature conditions of the hydrogen transition.”
