Why Metallic Hydrogen Is the Holy Grail of High Pressure Physics

[@Seeker]

Hi Seeker fam, As you've all already noticed, the molecule at the top of this video is not actually H2O, it's HO2, a simple, but critical mistake. In case you're wondering, HO2, also known as Hydroperoxyl radical, does actually exist! An oxygen radical, it's highly reactive ­- though it's molecular structure is a bit different than what's pictured above. Mistakes can be fun when they teach you new things? Learn more about HO2 here! - pubchem.ncbi.nlm.nih.gov/compound/520535#section=Top

The Harvard scientists who supposedly made and lost the Metallic Hydrogen said that they would try and recreate the experiment, although I haven’t been able to find out if they are still trying or not. I also want to add that working with extreme high pressure is very difficult and it isn’t unimaginable that something did go wrong, even if it can look a bit suspicious. Just a thought. I came upon metallic Hydrogen whilst working on a school paper for my exam, but I sadly can’t find a lot of information about the subject. I think it’s important to keep up to date with up and coming technology such as this, since it could easily be forgotten about and abandoned. I just want to say that you are doing great things spreading news about more unknown science, and explaining it at an easy to understand level. Keep it up.

To make the diamod anvils smooth enough to compress the hydrogen, they had to coat the contact surfaces with alumina, and some scientist speculate that's what underwent the phase transition, and not the hydrogen. That's just a hypothesis I heard, maybe even from Seeker...I can't weigh in, but it sounds plausible to a random KZbin commentor

01:28 "Instead of a molten iron core like inside of Earth" This doesn't make sense to me. Iron melts at 1,538° C, however the Curie temperature of Iron or 770° C is the temperature where Iron loses it's magnetism. How could Earth's core retain it's magnetic properties when it's at least 768° hotter than the point Iron loses it's magnetic properties?

[@fancypesto3647]

Because it's a bunch of electrically conductive mass all spinning around one common axis. The Curie temperature is for permanent magnets, what is occurring in the Earth is an induced magnetic field.

Metalic-hydrogen is the thermal regulator of the star's nuclear fusion reaction! If it's a superconductor, it maintains temperature "globally" at the contact surface of the hydrogen metal and the hydrogen liquid. It makes for very quick thermal discrimination at the quantum level.

[@chavezharding7820]

Ryan Smith It's a metallic bond... like in the name and the guy explained in this same video that there's so much pressure the electrons are freed from the complete pull of the neutron causing them to be free in a sea/pool of electrons as a result they are great conductors of heat and electricity which are both characteristics of the metallic bond.

The claim of a static pressure synthesis of metallic hydrogen was claimed purely from an iPhone picture- there were no data collected showing a metallic transition such as the disappearing of the hydrogen vibron seen by Raman Spectroscopy. They literally saw it go “shiny” in a microscope and took a picture and published a paper. It is completely disputed and does not count as a claim of synthesis of metallic hydrogen.

Well, I know that it's an incredible energy storage. Hydrogen + oxygen combination in itself is quite energetic. And if we make hydrogen more unstable by weakening it's bonds, it's explosive capability would become couple times as strong.
