Is a black hole matter? It's made by compressed matter, but is immune to proton decay? I need help.?

Question

I want to know if a black hole is matter.

Answer 1

As nwolfe35 said, you're not "inside" a black hole until you move beyond its event horizon, and it's there that science has absolutely no solid knowledge of what goes on. Most black holes result from super concentrations of matter, but it's unknown what the ultimate condition of that matter is. Then there's all the matter that's drawn into and beyond the event horizon; certainly it must all be reduced down to individual atoms, but again no one knows for sure.

Proton decay? No one has ever observed the decay of a proton, and it's only by employing certain equations related to the grand unification search that even plausible estimates of the time needed for a proton to decay can be found -- about 1^35 years!! (http://en.wikipedia.org/wik/Proton_decay#Experimental_evidence) Remember, protons are made of quarks, and quarks are thought to be absolutely stable.(http://hyperphysics.phy-astr.gsu.edu/hbase/particles/quark.html

Answer 2

A black hole is matter because it is a dead star that is decaying or has already decayed. The powerful force of the star pulling on the matter in space is what sucks the stuff into it as you know. The stuff that is in it will never get out and that's what makes it matter. The black hole will pull the proton in as if any other matter would be sucked in.

Answer 3

Loosely speaking, a black hole is a region of space that has so much mass (mass is matter) concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand black holes in detail, but let's start of slow, by thinking about gravity under fairly simple circumstances.


We consider proton decay in theories that contain large extra dimensions. If virtual black hole states are allowed by the theory, as is generally the case, then proton decay can proceed via virtual black holes. The experimental limits on the proton lifetime place strong constraints on the quantum gravity scale mnew (the effective Planck mass). For most theories, our constraint implies a lower bound of mnew > 1016 GeV. The corresponding bound on the size of large extra dimensions is ell < 106/n × 10-30 cm, where n is the number of such dimensions. Regrettably, for most theories this limit rules out the possibility of observing large extra dimensions at accelerators or in millimeter scale gravity experiments. Conversely, proton decay could be dominated by virtual black holes, providing an experimental probe to study stringy quantum gravity physics.

Answer 4

The term "Black Hole" refers to everything inside the event horizon of a black hole.

What CAUSES a black hole is called a singularity...and while a singularity starts off as matter, I seriously doubt it could be considered matter (as we know it) once it turns into a singularity and forms a black hole.

Answer 5

I think the definition of matter is anyhting with mass that has a particular volume. If a black hole's singularity has zero volume (as some scientists believe, but no one knows) then though it has a mass (very different from matter; e.g. energy has mass) it may not fit the precise definition of matter.

Answer 6

A sigularity is pure gravity. There are no atomic or sub atomic structures at least in the center.

Answer 7

Yes, it's incredibly dense matter. It's so dense that it's gravity becomes so strong that it collapses in on itself.
