However, once the colony reached an even higher, critical density
, enough AHL accumulated outside the cells forming a pool from which all the bacteria took their cue.
One natural question that arises in the context of Theorem 1 is the following: is there a nice graph class such that there a exists a critical density
c] represents the critical density
of evenly spaced points of viscosity data covering a very wide range, and [W.
This tested an idea, favored for the last 15 years, that not only is the universe made of a substantial amount of invisible and presumably exotic dark matter, but that there is enough of it to give the universe a critical density
- just the right amount of mass to keep the universe from collapsing of its own weight or expanding into infinity.
3, this homogeneous background dynamics is merely a Newtonian gravity model, with "dark energy" and "dark matter" used to pad out the critical density
and mimic a uniform expansion.
For instance, virulent species may lie dormant in a host until they reach a critical density
for releasing poisonous substances and resisting immune responses.
This recruiting map has two specific goals: to show the critical density
of the telecom industry in San Diego and to promote San Diego's world renown California lifestyle.
A possibility is that the Hubble constant was much higher in the past leading to a higher critical density
- cosmic inflation would still be necessary to overcome this issue.
The distant cluster also provides new evidence that the density of matter is lower than the so-called critical density
, the value required to keep the universe flat.
In a flat universe, the total density of energy and matter must equal the so-called critical density
For the universe to be flat, astronomers calculate that it must contain a critical density
A universe with less than the critical density
has a negative curvature and a shape akin to the seat of a saddle.
