Considering they will eventually be colliding gold or lead ions, will they measure or be able to measure the gravitational impact of the collisions? Just curious since the velocity will be so extreme. I would think Tevatron would already have something to say about this, but I'm unsure of the interest in testing it due to the fact that I've not seen anything at all down this avenue. I'd like to think such powerful collisions would create extremely minute, possibly measurable, vibrations. However, lacking the effort to run the numbers, I'm simply curious if anyone knows of any plan to test such. Cheers.
