After a long and tedious description of the problem — a simple container of fluid like the one I drew up above would work as well as his complicated «adiabatically insulated planet», he asserts that the «Greenhouse Effect» is entirely due to some sort of static gravitational effect that results in a «surface atmospheric mass density».

The linear elasticity model is then used to study the effects of lattice symmetry, mass density distribution and grain boundaries on the vibrational band structures.

«It is important to mitigate mass density fluctuations as a consequence of species separation because they could be seeds for hydrodynamic instabilities,» said Tilo Doeppner, coauthor on the paper and LLNL's experimental lead for ICF implosions using a CH (plastic) ablator.

More broadly, it also is a key component of the concept that the geometry of spacetime is curved by the mass density of individual galaxies, stars, planets, and other objects.

This implied that the mass density did not fall off with distance, at least to the distances Rubin observed.

Precisely how young depends on the mass density of the Universe, because the gravitational attraction of this mass acts as a brake on the Universe's expansion.

Quillen was also able to combine the new orbit models with the speed of the bar (which is rotating) to get a more refined estimate of the mass density 3000 light years from the Galaxy centre (about one eighth of the distance from the centre of the Galaxy to Earth), which is where the edge of the bulge is.

She first needed to understand what happens at the region of the resonance, which depends on the speed of the rotating bar and the mass density of the bar.

Using this information, Quillen could compute a mass density at the location of the resonance, which she needed for her model.

The mass density of the Universe is symbolised by the Greek letter omega (W).

He makes the standard assumption that the Universe began with the big bang and that its properties are determined by only two numbers: the Hubble constant, which describes the present expansion rate of the Universe; and omega (& Ogr;), the mass density of the Universe.

This theory of inflation, which gives us very good predictions for properties like the cosmic background radiation for the mass density of the universe, for things that we do really measure; that same theory in almost all of its forms predicts that there should not be just one universe, but the same mechanism that produced our universe [would] produce more and more universes without limit, producing an infinite number of universes.

In other words, the mass density of the universe was such that the universe is «flat»: it would not expand forever, but it would not collapse back on itself, either.
