Schwarzschild, Einstein, Hawking and Other Brilliant Scientists: Some Considerations About Black Holes

In 1916, Karl Schwarzschild solved the field equations for a static, spherically symmetric body, determining the metric of spacetime outside it after Einstein's General Theory of Relativity. This solution is crucial, supporting tests such as the shift of spectral lines, the bending of light, and the precession of planets. Schwarzschild black holes describe non-rotating spherical bodies with a central singularity and an event horizon, where nothing escapes the gravitational pull due to their intense gravity, making them invisible and challenging to study directly. Schwarzschild black holes usually form from the gravitational collapse of massive stars. When a star exhausts its nuclear fuel, it can no longer sustain its own gravity and begins to collapse. If the remaining mass of the star after the supernova explosion is sufficient, it will become a black hole. The hypothesis, called “black hole cosmology” or “Schwarzschild cosmology, ” suggests that our universe is part of a black hole within a larger universe. So our Universe may not have emerged from the Big Bang, but from within a black hole in a larger Universe.
