What Happens to Mass Inside a Black Hole?

In summary, according to classical general relativity, the mass inside a black hole is infinitely compacted at the singularity and time and space are also distorted. However, the Heisenberg uncertainty principle suggests that the singularity may not have infinite density due to "quantum jitters." The maximum predicted density at the center of a black hole is unknown.

Does mass exist inside a black hole?

What is the relative velocity between say me, and some mass inside of a black hole?

To what degree of time dilation/length contraction does mass inside of a black hole experience?

Try reading wikipedia at BLACK HOLE

http://en.wikipedia.org/wiki/Black_hole#Singularity


The mass inside, although not accessible to observers outside the event horizon, is infinitely compacted at the singularity inside according the classical general relativity. But this is not mass as we know it in everyday experience. Atoms, protons and electrons, for example, have been crushed to some unknown fundamental constitutents. And time and space are also mashed beyond recognition, perhaps to their fundamental constitutents.

There is not necessarily any motion between you and a black hole if you are a stationary outside observer; if you are falling in toward the black hole attracted by the gravity then of course there would be.

That is the final static condition. In the dynamical regime, a body crossing the black hole horizon will exist for some time "outside" the singularity.

According to the Wikipedia article on Black holes:
"At the center of a black hole lies the singularity, where matter is crushed to infinite density, the pull of gravity is infinitely strong, and spacetime has infinite curvature.[37] This means that a black hole's mass becomes entirely compressed into a region with zero volume.[38] This zero-volume, infinitely dense region at the center of a black hole is called a gravitational singularity." http://en.wikipedia.org/wiki/Black_...quantum jitters" is appropriately considered?

that the Heisenberg uncertainty principle precludes a black hole singularity of infinite density.
Is it after assuming change in position and that in velocity0?
[m*delta(v)]delta(x)=>h/2 delta(v) and delta(x) are small enough that m->infinity

FAQ: What Happens to Mass Inside a Black Hole?

What is the mass inside a black hole?

The mass inside a black hole is extremely concentrated and is often referred to as a "singularity." It is a point of infinite density and gravity, where the laws of physics as we know them break down.

How does the mass inside a black hole affect its surroundings?

The mass inside a black hole has an immense gravitational pull, which can affect the motion of nearby objects and even light. This is why black holes are often described as "cosmic vacuum cleaners," as they can suck in nearby matter and energy.

Can anything escape from the mass inside a black hole?

Anything that crosses the event horizon of a black hole, which is the point of no return, cannot escape its gravitational pull. This includes light, which is why black holes appear completely black and invisible to us.

How is the mass inside a black hole measured?

The mass inside a black hole can be measured indirectly by observing the effects of its gravitational pull on surrounding objects. It can also be calculated using Einstein's theory of general relativity.

Can the mass inside a black hole ever be observed or studied?

It is currently impossible to directly observe or study the mass inside a black hole due to its intense gravity. However, scientists can study the effects of black holes on their surroundings and gather information about their mass and properties through indirect observations.
