What happens to space and time at the singularity?
What happens to space and time at the singularity?
The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn’t really exist.
What is meant by space time singularity?
A spacetime singularity is a breakdown in spacetime, either in its geometry or in some other basic physical structure. It is a topic of ongoing physical and philosophical research to clarify both the nature and significance of such pathologies.
Does time stop in a singularity?
Time indeed does not progress at the singularity, because the singularity as classically described by general relativity is not part of our Universe and time has no meaning.
What is time like singularity?
A timelike singularity is one that is in the future light cone of some point A but in the past light cone of some other point B, such that a timelike world-line can connect A to B. Black hole and big bang singularities are not timelike, they’re spacelike, and that’s how they’re shown on a Penrose diagram.
Is time infinite in a black hole?
See my article Black Hole Mechanics. ‘Time-space’ is infinite, but not the black hole. The black hole will disappear in the very far future; space-time will continue as ‘Infinitum’.
Is a black hole a singularity?
In the real universe, no black holes contain singularities. A singularity is a point in space where there is a mass with infinite density. This would lead to a spacetime with an infinite curvature.
Did Einstein believe in singularities?
Closely related to his rejection of black holes, Einstein believed that the exclusion of singularities might restrict the class of solutions of the field equations so as to force solutions compatible with quantum mechanics, but no such theory has ever been found.
