Casimir Effect reversible?
Really tiny stuff sticks together, because at some point there’s less going on in the vacuum between them than there is going on in the vacuum around them. You know how when you try and meditate by clearing your mind and end up thinking about the fact that you’re thinking of nothing, and then eventually you’re trying to figure out what to eat for dinner? The universe does that too. Anyway, apparently these scientists have concieved of a lens that can reverse the effect.
A more technical description of the problem and solution is available here.
