French physicists may have successfully condensed hydrogen into a metal, thus creating metallic hydrogen. Many have claimed to have achieved this over the years, but nothing quite materialized to say the least. This discovery would give rise to room-temperature superconductors and help scientists understand how planets like Jupiter formed. The team used diamond anvil cells (DACs), or machines compromised of two diamonds to create tremendous pressure. Read more for another video and additional information.
“The scientists found that hydrogen transitioned into a metal when subjected to around 425 billion pascals, according to research published to the preprint server ArXiv. That’s nearly 4.2 million times more pressure than is exerted by the Earth’s atmosphere,” reports Futurism.
