What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

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 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 lattices generalize beyond the specific hydrides tested so far, and that a metastable, quenchable high-pressure phase can survive once pressure is released — the “chemical precompression” strategy several groups are actively…
Learn the underlying idea
A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
