Relativity - Curved space-time and geometric gravitation

Nettet1. des. 2024 · Sorted by: 2. In standard GR, nothing exists at the center of a black hole. The center of a black hole is a singularity, and because GR fails at that point it is simply removed from the manifold. That means that the singularity is not part of spacetime. To answer your question more realistically, we believe that GR is an approximate theory … Nettet8 timer siden · NASA 's James Webb Space Telescope (JWST) may have discovered the oldest black hole ever. Webb's onboard equipment allows it to look back to the earliest … NettetCurved space-time and geometric gravitation. The singular feature of Einstein’s view of gravity is its geometric nature. (See also geometry: The real world.)Whereas Newton thought that gravity was a force, Einstein showed that gravity arises from the shape of space-time.While this is difficult to visualize, there is an analogy that provides some … fmt in the uk
