>Ah well, we are all the product of light exceeding its own speed limit. Ergo we must be light but whom is the photon torpedo?

A question has tickled my mind for a long time. What is the speed of "sound" through a neutron star.

A mind experiment:

What if I had a lenght of very light yet strong magical metal rod (like the kryth that Niven's "Ringworld" was fabricated from) and it was a "light hour" in length (IOW light took an hour to trave from one end to the other).

Now what If I could hang it in space somehow. If I pushed on one end at one meter/second it seems that an observer at the other end would notice it immediately - and not an hour + 1 second after I "pushed" it.

I am sure somebody will argue that geometry (ie moving a point) does not qualify. But this is not a geometric point (like where the blades of scissors meet). I remember an idea using scissors with a 20:1 snip rate. If they were closed (snipped) at 10% of "C", the the point where the blades crossed would be moving at 2 x "C".

The "light" barrier is not a real limit - it is a limit of our understanding of physics. The next Albert E will break the light (or time?) barrier. Maybe he will come back and rescue us from ourselves:-)
