Could black holes just be very massive neutron stars?
Hi, new here, and this is something I could probably look up but I want someone to explain it to me so I understand it better.
The scientific community largely agrees that black holes are singularities- physics defying objects that cram all their mass into an infinitesimally small point. There’s probably a very good reason they all agree on this. Why?
Neutron stars are dense enough and formed in such extreme conditions that they are made of completely homogeneous matter that is packed as tightly as physically possible. They are demonstrably able to bend light around them as it is through gravitational lensing. Conventional wisdom would suggest that a black hole is the result of a neutron star simply accruing enough mass that light simply cannot escape. Beneath the event horizon it is fundamentally the same as any other neutron star, but because of its mass no light can escape
Alas, conventional wisdom has no bearing on scientific theory. So what evidence is it that suggests that black holes are something entirely different? Something conventionally impossible?
