Quantum levitation
Suspending a superconducting disc above or below a set of permanent magnets. The magnetic field is locked inside the superconductor ; a phenomenon called 'Quantum Trapping'.

That is how those round spacecraft work in our atmosphere.
But now we have to create a wormhole
Nice to make a fake ufo video without strings. and it Is an ufo lol

It would have been nice to see some tests with weights in, to see if it's really viable as a transport. But yeah, that's really cool.

And the point of this experiment is? transportation could never use this kind of technology due to the dangers.Could you imagine having to super cool a large vehicle with nitrogen and then it fails and crashes? think about the cost also.This will never be anything but an effective video.They would have to find a method of super cooling that's safe,install magnets rather than rails and then find a simple method of propulsion. would cost a boat load more than you think.

#9 and #10 this phenomenon has been known for a very long time. There is no need for this in transportation, maglev trains already get rid of the friction problem with simpler technology.
Anyway, as you can see, you can adjust this by hand, you must only overcome the force needed to move and create the defects in the superconductor. Also, you would need additional repulsion to work against the slow downward drift.

This is exactly the kind of thing the Physics recruiters use to hook people onto degree courses. Then before you know it you're up to your eyeballs in massive indecipherable textbooks, falling asleep in a succession of knackered old lecture theatres, while some seriously weird guy bores you with blackboard after blackboard of equation proofs.
Anyway, apparently they're coming up with materials that superconduct at higher and higher temperatures and they reckon they're aiming for room temperature, so the transportation prediction might not be so whacky after all.

Let's hope this does not end as another crazy Israeli Weapon Technology.

#10 This might become interesting again when superconductors become possible at close to room temperature. Who knows

#12 actually, for a real physicist, math is cooler than this flashy stuff. And it doesn't have all these experimental errors and broken hardware and noise.

That's one of the cooler things i've seen on snotr, both literally and figuratively.
