In case you haven't heard of the stuff, it floats around the universe doing something. Boffins aren't sure yet what it is, what it does or whether it's any use.
Still they'd like to find some.
So if you want to help, here's our INQBay auction to win your very own dark matter detector.
Simply email your bid in and if you're lucky you could soon be able to join in the hunt. We'll give you a day or so. Good luck! µ
