How can a singularity have zero volume?
The singularity is a point where volume goes to zero, not where mass goes to infinity. It is a point with zero volume, but which still holds mass, due to the extreme stretching of space by gravity.
How can black holes have zero volume?
A quantum gravity theory suggests that the cores of black holes may be a region of highly curved spacetime, rather than a singularity point with zero volume and infinite density. General relativity has been successful in describing the macroscopic properties of black holes.
What is the volume of a singularity black hole?
… black hole collapses to a singularity, a geometric point in space where mass is compressed to infinite density and zero volume.
How can something zero volume?
It is not possible for any object to have mass but zero volume, because in order for this to occur there would have to be infinite gravitational field around the object, and this does not happen in the natural world (I will come to the notion of “point particle” in quantum physics in a moment).
Does black hole have infinite gravity?
A black hole does not have infinite gravity. At a distance, the strength of the gravity is proportional to the mass of an object. Regardless of whether that mass is just a collection of ordinary material, or a black hole. A black hole does not have infinite gravity.
Do black holes have infinite volume?
Therefore, since the black hole is eternal, it could be said to have infinite volume (classically, but a real astrophysical black hole would have a finite but still extraordinarily high lifetime), as you’ll be integrating dt across its lifetime.
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 singularities have infinite gravity?
In the center of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.
Can matter have zero volume?
There is really no need for mass to take up any space. Current particle models say that all particles, both the massive and massless ones, are point particles with zero volume.
What has mass but no volume?
The modern view of the electron is that it is a point particle: it has a mass (9.109 × 10ˉ³¹ kg), but zero volume. (In the Characteristics section of the Wikipedia article , there is: “The electron has no known substructure and it is assumed to be a point particle with a point charge and no spatial extent.”
What is the difference between a singularity and a black hole?
This is the big bang. Therefore, the main difference is that a black hole singularity is the end of space time (and pulls matter in) and the big bang singularity is the beginning of space time (where matter and space were made ‘real’).
What is singularity and is it related to a black hole?
Singularities. In the center of a black hole is a gravitational singularity, a one- dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.
How does a black hole become a singularity?
The black hole singularity occurs when physics stops working . Eduard Larrañaga is a theoretical physicist and professor at the National Observatory of Colombia. He explains that black holes were an Einstein theory before their existence was proven. ‘The general theory of relativity goes back to 1916.
What does a singularity of a black hole look like?
From concepts drawn from rotating black holes, it is shown that a singularity, spinning rapidly, can become a ring-shaped object . This results in two event horizons, as well as an ergosphere, which draw closer together as the spin of the singularity increases.
