| According to most theories of dark matter, it is too energetic to have been created by the annihilation of dark matter particles. |
| It is most likely that particle physicists will find dark matter, if indeed it exists in particle form. |
| They discussed the understanding of dark matter by the use of gravitational lenses. |
| Well, what you can see are the gravitational effects, both of dark matter and of the dark energy. |
| So far the most promising candidate for dark matter is the neutralino, because they interact weakly. |
| This gas forms part of a gigantic system of hot gas and dark matter that defines the cosmic landscape. |
