Another cracking photograph. I find it hard to contemplate lightspeed, to us the concept of it seems an unattainable speed.

However when one looks at the universe I also have trouble wrapping my head around the fact that it is pretty slow, in that nothing is faster? I mean slow in the sense that it would take billions of years to get from one side to the other, how can this be the fastest thing known to science?

Anyway I'm waffling....nice pic.
