The passage around this formula

A grounded scenario, not a prediction, follows from the confirmed hydride results: if a phonon-mediated hydride superconductor can be found or engineered that maintains a high TcT_c at pressures compatible with practical devices — rather than the diamond-anvil-cell pressures used in the confirmed 2015–2019 results — it would represent a genuine advance even short of ambient pressure. The assumptions this scenario depends on are that light-element, high-phonon-frequency…
