Like ordinary matter, dark matter interacts gravitationally with ordinary matter and radiation. Astronomers study the distribution of dark matter through observing its gravitational effects on ordinary matter in its vicinity and through its gravitational lensing effects on background radiation. The background image shows the bullet cluster, a famous example where the visible matter does not follow the mass distribution.
Combining all the available evidence, dark matter represents about 83% of the matter content of the universe. Read more about dark matter on this web page. Let us know your questions and comments on the message board.
Hello, I am a Scuba instructor in my spare time in Dallas, Texas.
camb_legacy tasks temporarily suspended
Hi everyone, there's something wrong with the camb_legacy tasks, possibly related to a recent upgrade. I've temporarily disabled them (no validation, no new workunits created) until I can figure out the problem. The camb_boinc2docker application is still working normally.

Hi folks, I've made a few tweaks to the website theme. Hopefully this makes it a bit easier on the eye. These changes should also improve usability on mobile somewhat, although some work remains to be done. For now, please report any theme / user interface bugs you may find on this thread! Thanks!

Fill out a survey to help Cosmology@Home
Hi everyone, graduate student Lo Lee and Professor Peter Darch of the University of Illinois (where we got our start back in 2007) are conducting a survey of Cosmology@Home users for their research. If you have a moment, we'd appreciate if you could fill in the survey at https://illinois.edu/sb/sec/2695704. Your (completely anonymous and confidential) responses may also help us guide the design of Cosmology@Home in the future. Many thanks!
