The smaller an object the further its ratio of ordinary matter to
dark matter is from the cosmic mix.

others if others are interested in us and concerned about us.
As he and other atomic physicists consider other types of exotic matter to
mimic using Fermi gases, no prospect generates as much excitement as superconductors.
The change in sound marks the time when the universe is cool enough for photons and atomic matter to
Nicastro adds that mapping ordinary matter will reveal the location of dark matter This invisible material is believed to be the stuff that coalesced first in the universe, which triggered ordinary matter to
clump into galaxies.
We hypothesize the existence of dark matter to
explain observations that could be attributed to gravitational forces, but we don't know what dark matter might be.
Whenever gravity caused matter to
compress, the pressure exerted by the trapped photons offered resistance.
It's common during phase transitions, like water's familiar ones, for bubbles of unchanged matter to
linger and then suddenly and violently burst in a belated transformation into the new phase.
He cautions that as astronomers probe farther and farther out from a galaxy's visible core, it may become difficult to ascribe dark matter to
a particular galaxy.
A variety of observations, however, including measurements taken over the past year, has revealed that the universe comes up short: It doesn't have nearly enough matter to
A low-weight universe does not have sufficient density of matter to
Today's galactic architecture, says Szalay, is consistent with a low-density universe-one that expands forever-containing a relatively high proportion of ordinary matter to
