There was another paper about 15 years ago where a electrically pulsed, superconducting thin film was able to displace a pith ball from tens of meters, through walls. I can't find the paper but it was on arxiv. Some sort of gravity pulse; weird shit.

Made me think of this. Maybe when they were doing the experiment, a gravitational wave happened and they somehow reflected it?

> Thin superconducting films are predicted to be highly reflective mirrors for gravitational waves at microwave frequencies. The quantum mechanical non-localizability of the negatively charged Cooper pairs, which is protected from the localizing effect of decoherence by an energy gap, causes the pairs to undergo non-picturable, non-geodesic motion in the presence of a gravitational wave.

They were able to repeat it. Damn, I wish I could find it. I actually have it printed off somewhere.

The issue is that distorting gravity has far more consequential effects due to generally relativity than just moving something. You are actually distorting time too.

That explains the significance of the floating hole-puncher confetti in the movie Primer.
