It’s Becoming Clear Why Black Holes Never Run Out of Fuel
Teruyuki HayakawaSpaceJul 27, 2026 5:00 AMIt’s Becoming Clear Why Black Holes Never Run Out of FuelBlack holes eject powerful energy jets that blow away the surrounding gas to great distances. These jets heat the surrounding gas, delaying the formation of new stars and affecting the growth of the galaxy as a whole.This has long presented researchers with a puzzle. As a black hole emits jets and heats the surrounding gas, the gas that would otherwise be consumed by the black hole—that is, its energy source—is dispersed far away.
