Sentences with phrase «at critical density»

Schwarzschild's results showed that, at some critical density, the star's gravity would become so strong that it would swallow everything — matter, light, even space and time — within a specific radius.

Crucially, the math showed that ironing out temperature wrinkles in the cosmos would also leave the universe at critical density — delicately balanced between continuous growth and eventual collapse to a Big Crunch.

If the density is poised precisely between those extremes, at what is called the critical density, space would be uncurved — flat — and the slowing would continue forever.

The anomalous thermodynamic properties of water point to the possible existence of two different liquid phases — one with high density and the other with low density — that become identical at a liquid - liquid critical point in the supercooled phase (C ′, see the figure).

In the copper - oxide material, instead of raising the temperature, the scientists raise the level of doping to «melt» the density waves at a particular «critical point.»

The same thing held our species back, until the population reached a critical density, unleashing the power of culture — at which point there was no stopping us.

Homer 1, an actin binding protein that is induced by BDNF [72], belongs to a family of scaffolding proteins that localize at the postsynaptic density (PSD)[73, 74] and is believed to play a critical role in signal transduction, synaptogenesis and receptor trafficking at synapses [75].

In 2005 worldwide CO2 emissions amounted to nearly 28 Gt; even if were to set out only a modest goal of sequestering just 10 % of this volume we would have to put away annually about 6 Gm3 (assuming that all of the gas is compressed at least to its critical point where its density is 0.47 g / mL).
