Does a singularity have volume?

Curvature is measures as 1/radius^2 so that as the radius ‘goes to zero’ the curvature of space becomes infinite. That being the case, singularities never have zero volume, but reach the limiting scale for space-time at about 10^-33 centimeters.

How can a singularity have infinite density?

The singularity of a black hole is the only part that has infinite density. As soon as the body of mass is contained totally within its Schwarzschild radius (that is a very high but definitively finite density) you have a black hole – nothing inside it can escape.

Do white holes have negative mass?

As I understand, white holes are an exact opposite of black holes, Black Holes are condensed of positive mass, where it is so heavy that it attracts everything into it. White holes are opposite, they repel everything that goes around it and give out ‘stuff’.

Do black holes have a 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. Something has to replace the singularity, but we’re not exactly sure what.

Is singularity a point mass?

A space-time singularity point contains all the mass of the celestial body. In terms of black holes, the event horizon contains no mass whatsoever. But yes, a singularity point has mass. A finite mass contained in an infinitely small area.

Do white holes have mass?

To a spaceship crew watching from afar, a white hole looks exactly like a black hole. It has mass. It might spin. A ring of dust and gas could gather around the event horizon — the bubble boundary separating the object from the rest of the universe.

What is the meaning of white hole in general relativity?

General relativity. In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape.

What are white holes?

White holes are theoretical cosmic phenomena that function in the opposite way as black holes; instead of attracting matter into an infinitely dense singularity due to immense gravity, it pushes out matter and light, preventing anything from re-entering past its event horizon.

Will White holes come to dominate the universe?

In this picture, white holes would one day come to dominate the universe, after the stars have burnt out and black holes have withered. Any observers then could easily detect the objects as relatively large particles Haggard speculates, but those days are countless trillions of times the current age of the universe in the future.

What is the acceleration due to gravity on a black hole?

Acceleration due to gravity is the greatest on the surface of any body. But since black holes lack a surface, acceleration due to gravity increases exponentially, but never reaches a final value as there is no considered surface in a singularity.
