>Squeezed between two pieces of diamond, hydrogen has been transformed into a metallic form believed to exist inside giant planets like Jupiter, scientists reported on Thursday.

>“You can see it becomes a lustrous, shiny material, which is what you expect for a metal,” said Isaac F. Silvera, a professor of physics at Harvard.

>If some theoretical predictions turn out to be true, the new state of hydrogen could even be a solid metal that is metastable — remaining solid even after the crushing pressure is removed — and a superconductor, able to conduct electricity without resistance, Dr. Silvera said.

>Dr. Silvera and Ranga P. Dias, a postdoctoral researcher, published the findings on Thursday in the journal Science.

>But in the small but contentious field of high-pressure physics, some scientists who perform similar experiments were harshly skeptical and wondered how the research passed peer review at a top journal like Science.

>“It’s — how should I put it? — the product of Ike’s imagination from the title to the end,” said Eugene Gregoryanz, a physicist at the University of Edinburgh in Scotland. Paul Loubeyre, a physicist at France’s Atomic Energy Commission, wrote in an email, “The fact that the paper went through illustrates the fact that the reviewing process has some flaws.”

>Editors at Science declined to discuss the paper, but in a statement, Jeremy Berg, the editor in chief, said that submissions must pass rigorous review by experts and that only about 7 percent are published.

>Dr. Silvera defended his work. “If we did it again, we’d get the same result, I’m certain,” he said.

>Hydrogen is the lightest of elements; each atom consists only of one proton and one electron. In the ordinary conditions at Earth’s surface, where the weight of air presses at 14.7 pounds per square inch, hydrogen atoms pair up into simple molecules.

>At supercold temperatures, hydrogen molecules first condense into a liquid, then a solid with the molecules intact. When squeezed together, the molecules stack up into a solid form. More than 80 years ago, the physicists Eugene Wigner and Hillard Bell Huntington predicted that hydrogen, under high enough pressures, would turn metallic, with the hydrogen molecules broken apart and the electrons squeezed loose.

>Scientists have momentarily transformed hydrogen into a liquid metallic state with violent shock wave experiments. Planetary scientists are convinced metallic must exist inside Jupiter, to generate that planet’s powerful magnetic fields.

>But so far, no one has convincingly demonstrated the solid metallic hydrogen state predicted by Wigner and Huntington. In the Harvard experiment, a small amount of hydrogen was placed between two diamond tips about one 850th of an inch in diameter and cooled to -433 degrees Fahrenheit. Initially transparent, the hydrogen became dark as it was squeezed. Then, at nearly 72 million pounds per square inch, the hydrogen became shiny, reflecting 90 percent of light shining on it, the scientists reported.

Maybe used as a rocket fuel together with LOX. You wouldn't have to pressurize it, so you'd save weight.

You dont need to lower the temperature of something to put it into a liquid state.

Just look at co2 on the surface of venus.

I believe lowering the temperature of hydrogen atoms causes them to contract and makes it much easier to apply pressure from the diamonds. However in a place like jupiter im sure the pressure far exceeds 72m ppi

Lowering the temperature of the hydrogen doesn't make them contract, it just reduces the amount of energy that each molecule has, which makes them more readily condense to a solid

What does pressure have to do with saving weight?

The rocket fuel application has to do with the fact that burning the stuff solid would be safer and release a lot more energy.

Lowering of standards to pander to retards who don't know shit through big-name association is a pretty common theme in modern science unfortunately. It's the same in my field. The fact silvera says
