Oxford Students discuss Dark Matter.
For over three millennia, astronomers have been observing the heavens. Yet, less than one hundred years ago, observations were made suggesting the existence of a previously unknown substance, permeating the universe in vast abundance, yet invisible to even the most powerful telescope. This substance has been aptly christened 'dark matter', and though in nature it seems to be ubiquitous, all attempts to explicitly detect it have hitherto been unsuccessful. So, what is dark matter, why do we think it exists, and what has it got to do with a four-ton tank of liquid argon, two kilometres underneath Ontario?
