minus-squarewoodenghost [comrade/them]@hexbear.netlinkfedilinkEnglisharrow-up6·28 天前Actually you wouldn’t notice anything special crossing the event horizon. You’d just continue to fall.
minus-squareddh@lemmy.sdf.orglinkfedilinkEnglisharrow-up4·27 天前Sounds like they are referring to the photon sphere.
minus-squareCat_Daddy [any, any]@hexbear.netlinkfedilinkEnglisharrow-up2·27 天前I assumed it would be further inward than the photon sphere because heat radiation is (also an assumption) easier for gravity to hold back than light. I don’t know how “heavy” a star’s heat is, though, so ¯\ˍ(ツ)ˍ/¯
minus-squaredwindling7373@feddit.itlinkfedilinkEnglisharrow-up2·27 天前Heat radiation are particles with a mass and a certain speed, they are all by definition heavier and easier to trap than photons. In terms of escape velocity, nothing can try to escape faster than light.
