can anyone shed some light on this r>=0 theory ive heard about....

Einstein's equations contain a term that involves dividing the mass of the black hole by the distance "r" from the black hole. The question is what happens when r=0? Division by zero gives a result of infinity. To physicists, it is impossible for infinity to appear in the real world, so they consider r = 0 to be the point at which physics breaks down. At r = 0, the centre of a black hole, gravity is infinite and time itself stops: all of the mass of the black hole is contained within an infinitely small point where the concept of space no longer makes any sense. The point takes up precisely no space at all. Since this point is outside space and time, it is dimensionless. The physical universe collapses into an ineffable twilight state at this point. This apparently impossible object of infinite density and infinite gravity is known as the singularity. No predictions can be made about it, or about what might emerge from it. At the singularity, The one thing no physicist has ever contemplated is this: there is no flaw whatsoever. The reason why physics seems to disintegrate at r = 0 is for the extremely simple reason that r = 0 is not in the physical universe. It is in the mental universe, the universe of mind, The dimensional aspect of existence is associated with the dimensions of space and time. The dimensionless aspect, since it has no dimensions, is outside of space and time. This is the key aspect to existence: an aspect outside of space and time perpetually interacting dialectically with an aspect inside space and time. the Big Bang singularity itself is a dimensionless entity

General Relativity provides a stunningly accurate account of how gravity dictates the motions of planets, stars and galaxies (the universe of the very large and very fast), but it cannot describe the universe of the very small (atoms and subatomic particles), from which all the planets, stars and galaxies are constructed. Here, the effects of gravity on these hypersmall, hyperlight entities are negligible.The two theories meet head-on at one place: black holes. A black hole is a macroscopic entity associated with enormous amounts of mass and gravity, yet the singularity at the centre of the black hole is exactly of the hyper-microscopic scale of the quantum world.

The r = 0 domain can be considered the primary reality because there are no circumstances in which it could ever disappear, whereas it is possible to imagine the r > 0 domain shrinking down to r = 0 i.e. for the dimensions to be removed from dimensional existence, leaving nothing but dimensionless existence.

The r > 0 domain can emerge as an emanation from the r = 0 domain (in an event such as the Big Bang), but the r = 0 domain can never emerge as an emanation from the r > 0 domain because it is impossible for the r = 0 domain not to exist. It's possible to subtract dimensions from dimensional existence, but not to subtract dimensions from dimensionless existence since there were no dimensions in the first place.
