      I'd like to think you're joking, but since I'm not sure I'm going to reply anyway.

      They were expecting the jumping to be equivalent to about a magnitude 3 earthquake on the Richter scale which is a common seismic event that shows up on seismographs but which people can't even detect. A significant quake will be more like a 5 or higher on the Richter scale. This scale is logarithmic so a 4 is actually 10 times more powerful than a 3, and a 5 is 10 times a 4.

      Thus the scientists would have to have been mistaken about the impact of all that jumping by a factor of 100 to actually rattle people. Any scientist worth his salt ought to be able to estimate the effect of what he's doing more precisely than 2 orders of magnitude, especially if it might be dangerous for him to be wrong.

      OK, first you say the light will be incredibly scattered, weakening and dispersing the light so much that it's worthless. Then you say that it's nearly impossible to hit the moon from such a distance.

      Now, the question I pose is that if the light is so dispersed by the time it reaches the moon, couldn't you just point it in the general direction of the moon and have some miniscule fraction of the light reach it? Then with so many people contributing their tiny fraction, the net result might just be a noticeable effect.

      However, depending how much the light is dispersed (presumably quite a bit) and how much light is absorbed by the time it reaches the moon (practically all of it), you'd probably need more than you and a couple of your buddies doing it.
