Tanelorn said:I just wanted to explain my question again:
Most Physicsts agree that there is likely no true singularity and that what is required is a theory of quantum gravity to explain what is going on. Some say that the singularity inside a black hole is of the order of the Planck length ie. one notch above a true singularity. I am asking if there are intermediate states of collapse to prevent matter collapsing to this state?
If heavy enough a massive star can collapse to a neutron star.
A heavier star might collapse to some other denser stable form of matter eg. a quark star.
A still heavier star might collapse to some other denser form of matter which is still larger than the Planck length.
A still heavier star might collapse to a black hole whose singularity is the Planck length above.
A super massive black hole has collapsed to a Planck length singularity, but the mass and thus density is higher than the previous case.
This is the question I am asking.
There is something called a black star which considers the idea of degenerate spacetime-
