2 AntwortenGarden & Landscapevor 6 JahrenFormation of black holes and thermodynamics?
If nothing can escape from a black hole, I can't see how they can form in the first place. When the solar system was formed, the solar system would never have contracted into a sun and planets without radiating huge amounts of heat into empty space. If a black hole can't do this then that would seem to halt its contraction, or at least convert its contraction into an infinite asymtote such as 1/x goes to zero as x goes to infinity. Any thoughts?
