Wikipedia said:Many theories in physics have mathematical singularities of one kind or another. Equations for these physical theories predict that the rate of change of some quantity becomes infinite or increases without limit. This is generally a sign for a missing piece in the theory, as in the Ultraviolet Catastrophe and in renormalization.

As far as I know, and correct me if I am wrong, the classic 1915 version of GR is pretty much as it is now. It is true that the contemporary mathematical treatment is different from Einstein's days but as far as I know the theory itself has not changed one single bit. Also, as far as I know, and correct me if I am wrong, there is no such thing as a quantized general theory of relativity. Many people hope to present such a theory but so far no one has been able to present it.marcus said:So at the center of a black hole the classic 1915 version of General Relativity breaks down.
But a quantized version that some people are using does NOT break down.

Yes, but I would not wager that any leading LQC theoretician is going to make a claim soon he or she developed a quantized general theory of relativity.marcus said:The current leading theory as regards BB and BH is Loop Quantum Cosmology LQC.
Arch2008 said:...your description of Loop Quantum Cosmology as a leading theory, Marcus.

the singularity of a black hole is a theoretical place where all matter comes to an end, where it is all crushed. the singularity has infinite density and infinite gravity, supposedly. so when an object is sucked into the black hole, it is first stretched into sphagetti because of the very strong pull and then it goes to the singularity. in a singularity, the fabric of matter is broken down and space and time ceaes to exist.
this is just a basic definition of a singularity. if you need more info visit,

hope you find it useful
A singularity is a point in space where the gravitational pull is infinite and the laws of physics break down. It is typically associated with black holes, where the mass is compressed into an infinitely small point.
Singularities are caused by massive objects, such as stars, collapsing under their own gravity. As the mass becomes more and more concentrated, the gravitational pull becomes stronger, resulting in a singularity.
According to our current understanding of physics, nothing can escape a singularity. The gravitational pull is so strong that even light cannot escape, hence why black holes are called "black".
The laws of physics, as we know them, break down inside a singularity. It is believed that space and time become infinitely warped, and matter is crushed into an infinitely small point. It is impossible to know for sure what happens inside a singularity, as our current understanding of physics cannot fully explain it.
There is currently no consensus among scientists about this. Some theories suggest that the singularity at the center of a black hole and the Big Bang singularity may be connected, while others propose that they are completely separate phenomena. Further research and understanding is needed to fully answer this question.
