Dark matter, and how we would not be alive without it
MetadataShow full item record
Most of the mass in the Universe is of some unknown form of matter. While we have some guesses what it might be we are not sure. In this talk for a non-specialist audience, Professor Abel will explain how observations using telescopes convinced the scientists that Dark Matter must exist. He will also show how without it we would not even be here. Using videos produced from his supercomputer calculations we can see how stars and galaxies are formed in virtual universes that have a striking resemblance to our own. Without dark matter none of this would work. The talk will also explain current experiments on the way that have the hope of discovering what this dominant part of the Universe may be made of.
