Have scientists produced a speck of solid metallic hydrogen?

My annual birthday-month fund-raising drive for Behind the Black is now on-going. Not only do your donations help pay my bills, they give me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.


Please consider donating by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below.


Regular readers can support Behind The Black with a contribution via paypal:

Or with a subscription with regular donations from your Paypal or credit card account:

If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage. And if you buy the books through the ebookit links, I get a larger cut and I get it sooner.

Scientists using a diamond vise think they have produced the first speck of solid metallic hydrogen, potentially capable of being a superconductor at normal temperatures.

While the scientists who performed the experiment believe they have succeeded, others are skeptical. Read it all. This is quite fascinating research.

    The new Feishman and Pons?

    If this is indeed true in all of its aspects, what mechanism is proposed that would allow metallic hydrogen under such intense pressure to remain in its metallic state sans the pressure?

    ….”what mechanism is proposed that would allow metallic hydrogen under such intense pressure to remain in its metallic state sans the pressure?”

    The same mechanism that lets a diamond stay in its metastable state when the temperature drops and the pressure is let up and the thing stays a diamond instead of going back to graphite, until you raise the temperature above the critical point again, of course.

    Metastable states are tricky that way.

    Sometimes the critical temperature is well *below* room temperature. Sometimes they are several thousand degrees Kelvin.

    Ya dinna knooo, till you try it laddee!

    They haven’t dropped the pressure yet. I assume they’ll try that first. They haven’t raised the temperature yet.

    They may be just a wee bit nervous!

    Slightly off subject but related to hydrogen and cold … an interesting read
