Compactness of a black hole
WebApr 10, 2024 · A black hole is a dense, compact object whose gravitational pull is so strong that – within a certain distance of it – nothing can escape, not even light. Black holes are thought to result from the collapse of … WebApr 11, 2024 · As a general conclusion, note that the more negative \(\xi\) is, the greater the compactness. Depending on the value of \(\xi\), the 4/9 (Buchdahl limit) and 1/2 (black hole) compactness of GR can be exceeded. A relevant question that arises is what is the limit of the compactness of stars in the f(T) gravity, in particular in the one studied here.
