see, that's actually a pretty cool analogy, because a lot of the theories surrounding superdense black holes involve them being (for want of a better word) a 'hole' in the universe - a dip or puncture in space-time. As 2D representations go, the hole in grip tape isn't too bad.
It's well known that Gnarvity warps timespace.
That picture doesn't seem right. I'm sure there should be at least some vortex around the event horizon, but if Nasa has decided to publish it....
