A Breakthrough in the hunt for Metallic Hydrogen? [2020]

A team led by French Physicist Paul Loubeyre, used an updated version of the DAC method, and are claiming to have produced metallic hydrogen. At least they stated that the results are consistent with the transition from liquid to metallic, as predicted by supercomputer algorithms.
The trick was to use a new diamond tip shaped in a toroidal format. It was first introduced back in 2018, only one year after the Harvard team made its first observations.
Before this, the diamond was shaped with squared faces that looked something like this. (show image of diamond)
Side by side and the difference is apparent.
By just changing the form of the diamond tip, some experiments have reached TPa levels, opening a new door to high pressure physics research and solving one of the major limitations of this technique.
