Anything or anyone who falls through the event horizon will soon reach the region of infinite density and the end of time.

It doesn't have to be a mathematical point, but could be a line, or even a sheet, of infinite density.

The singular region can thus be thought of as having infinite density.

This state of infinite density is called the big bang singularity.

The universe might then have re-expanded without going through a state of infinite density.

A singularity is a point with an extremely high temperature and infinite density.

In a closed universe, the end point for that approach is a collapse to a point of infinite density, pressure, and temperature.

They feel certain, for example, that black holes indicate regions where matter has been compressed into an infinite density.

In the beginning, according to this model, mass was compressed into a state of infinite density, an initial singularity.

Everything would then be crowded together in a state of infinite density: the end of the universe.
