"Webb4 feb. 2024 · The scientists first published this idea in 2024. Now, they have firmed up the numbers. In order to receive strong enough CMB light, a planet would need to orbit very close to the black hole's event horizon. Normally an object that close would soon get sucked in. If the black hole is spinning fast, however, close stable orbits are possible. " - Smallest black hole possible
