Comment on Observation of the Wigner-Huntington transition to metallic hydrogen

Understand

A recent paper of Dias and Silvera (DS) reports on production of metallic hydrogen in a diamond anvil cell at 495 GPa at 5.5 and 83 K.

• The results are implied to have a great impact on energy and rocketry.
• Here we argue that the presented (very scarce) results are contradictory with the presented experimental description making their claims unsupported experimentally.
• Moreover, the proposed implications are highly speculative making this paper very confusing for a broad audience.
