Re:So I read the article... (Score 2, Insightful)

The paper hints that the results at 150m were about identical to those at 6m. It seems the 'wave' travels freely through matter, and then only effects the ball at the far end of the setup...i assume this discriminatory behaviour is because the ball is moveable. so all the fixed obstructions eg. wall etc, simply don't take any energy from the wave. the wave can't have infinite energy, it seems reasonable to assume. but then what about the 150m of freely-moveable air molecules in between? surely a lot of air gets moved (depending on the width of the beam) and should influence the results at 150m. there's a general lack of experimental thoroughness in the results.
