From the Ted Talk by Patricia Burchat: Shedding light on dark matter

Unscramble the Blue Letters

And again, what we find is that there is much more mass there than can be accounted for by the galaxies that we see. Or if we look in other patrs of the electromagnetic spectrum, we see that there's a lot of gas in this cluster, as well. But that cannot account for the mass either. In fact, there appears to be about ten times as much mass here in the form of this invisible or dark mtaetr as there is in the oadnirry matter, OK. It would be nice if we could see this dark matter a little bit more directly. I'm just putting this big, blue blob on there, OK, to try to remind you that it's there. Can we see it more visually? Yes, we can.
