0 (according to some theories of the universe) a substance existing in space that does not give off any light:
Our research is focused on dark matter and in particular what we can learn about it using astrophysics.
In particular, the concepts of dark matter, dark energy, and cosmic star formation history will be discussed, and their relation to the existence of intelligent life will be explored.
The missing component is known as dark matter and its nature is unknown.
Despite not solving the dark matter problem, microlensing has been shown to be a useful tool for many applications.
The third peak can be used to get information about the dark matter density.
These are not particles in the particle physics sense each particle represents approximately a billion solar masses of dark matter.
During matter domination, all causal dark matter perturbations grow through gravitational clustering.
At this stage, luminous, baryonic matter is expected to simply mirror the evolution of the dark matter, and their distributions should closely trace one another.
By mapping the distorted light created by gravitational lensing, astronomers can trace how dark matter is distributed in the cluster.
