Do you think string theory has anything to do with the gravity dips surrounding masses? I saw a string vibrate and from the side it looks like dips I have seen in theory creations from artists that draw dips in space surrounding masses like stars and blackholes.

I passed Henry Wilson's question on to Steve Blau of Physics Today magazine, and here is his response.-- Ed Lee, Physics To Go site editor
My answer to Henry Wilson would be "yes and no." String theory has as a goal to be a theory of gravity. That's the yes part. But the visual coincidence he noted is just that, a coincidence. The string displacement is a displacement of physical string acted on by an external vibrator. I'm not sure I understand the gravitational "dips in space" that he refers to but I'd guess they are either the warping of spacetime by a gravitational masses, or a potential energy diagram. In either of those two cases, the physics is quite different from that of a vibrating physical string.
