I think the comparison you're giving here is quite misleading. You're implying that we "only" need to scale up the objects we put in quantum superposition by tens of thousands of times. But that's not all there is to it. You'd have to put it in a kind of superposition that affects its mass enough to be measured. For instance, having the whole object be in superposition of one position, or another position several centimeters away. Or being in an extremely high energy state vs extremely low energy state, with an energy difference on the order of 90mg. Given E=mc2 that's an insane amount of energy.
Seems to me that such an experiment is borderline unthinkable with present day technology.
- eterevsky 3y agoI do understand that there's more to it than just closing the gap of 90'000x. That said, the fact that these numbers are on roughly the same order of magnitude makes me cautiously optimistic. If anything, to me both measuring the gravity of 90 mg weight and putting a crystal that you could see with your naked eye into quantum superposition already seem borderline unthinkable.
