They are, then, the plenum, that is to say, the condition of an infinitely dense universe, but nevertheless they are unextended.

It is logical to call the time that has elapsed since everything was in that infinitely dense singularity the age of the Universe.

Hubble's observations suggested that there was a time, called the big bang, when the universe was infinitesimally small and infinitely dense.

An infinitely dense RI map should average four times the length of the conventional one-generation F2 map.

Even "black holes" have mass and volume - very dense, Yes, but not "infinitely dense".

Second, all solutions suggest that there was a gravitational singularity in the past, when R goes to zero and matter and energy became infinitely dense.

The ring nucleus here is a singularity, an infinitely dense zone where light and spacetime cease to exist.

If you extrapolate backwards from what we can model/describe, you might predict an infinitely dense singularity (zero volume) from which the universe began.

In the beginning, according to the theory, the universe was infinitely hot, infinitely dense.

A naked singularity could allow scientists to observe an infinitely dense material, which would under normal circumstances be impossible by the cosmic censorship hypothesis.
