"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used.

So, instead of thinking of gravity as an invisible force pulling ... field and the curvature of the spacetime.” “The obtained ...
