Nuclear Reaction Defines the Abyss for Black Holes ⚡ экспресс
Original: "Nuclear Constraints on $$^{12}$$C$$(α,γ)^{16}$$O and Their Impact on Black-Hole Mass Predictions"
Refined nuclear reaction marks the edge of the abyss: ordinary black holes weigh between 61 and 75 Suns.

A tiny nuclear reaction carbon+helium decides a star's fate: whether a black hole is born or not. New data: the heaviest ordinary black hole weighs 61–75 Suns. Gravitational waves can test nuclear physics!
🎯 The carbon-helium reaction is so slow that the slightest acceleration would deprive the universe of carbon-based life.
\frac{M_{\rm BH}}{M_\odot}\simeq 61\text{--}75
