    (Please note that this is not the speed of light in a vacuum but the speed of light in a medium.)

    So, these gamma rays are moving faster than light in a medium, through the jets, and appear to be going backward through time. This is so interesting to me because it shows that things can move faster, in a medium, than the speed of light.

    Although it's a lot less interesting than I thought because the first time I read it I thought that it was actually talking about the speed of light in a vacuum. That was yesterday. When I re-read it today I realized I misunderstood.

    Don't get it. If this is an observation then how? How can someone "see" something move back in time?

    They see another identical pattern farther along the jet.
