In short, at the critical density, expressed as omega-equals-one, the universe would be in a state of equilibrium between collapse and eternal expansion.
32.
The cosmological constant, the energy of empty space, would account for the balance of 70 percent, bringing the universe up to critical density.
33.
They may help distinguish between missing-energy models and provide clues that the universe should consist of what is known as a critical density.
34.
The Kessler syndrome, a runaway chain reaction of collisions exponentially increasing the amount of debris, has been hypothesized to ensue beyond a critical density.
35.
"There's no center, no critical density, " says Gordon Davidson, artistic director of the 760-seat Mark Taper Forum, easily the city's best-established regional theater.
36.
If the universe has less than critical density it expands forever and is not in a process of implosion and not a black hole.
37.
In that case, cosmologists are faced with figuring out how explain missing-energy values of as much as 70 or 80 percent of critical density.
38.
What we didn't know is that there is a critical density of animals that you can't fall below, or the entire population collapses ."
39.
Omega is the ratio between the actual density of the universe and a value called the critical density that is required to support equilibrium.
40.
The upper and lower limits of this test are based on critical densities m c where control of a pest requires action to be taken.
