As probably the only person who will respond without trying to answer or further your line of questioning, I&#x27;d like to say how ridiculously cool that video is. Whenever anyone asks why I armchair-physics, I just show them that. Because, come on.<p>I mean, sometimes, we have to stop and realize how <i>cool</i> this stuff is. I may or may not be alive when we figure out how to use that sort of quantum locking IRL, but I would love love to be able to get a quick peek at 150 years from now before I go.
