What material and setup could even fake that result?
- RivieraKid 3y agoAnd why fake it in the first place? I don't see the benefit.
- Koiwai 3y agoIt's a bit hard to break it to you, but Santa isn't real.
- RivieraKid 3y agoWhat's your point?
- Koiwai 3y agoAre you living in the fairy land? in the real world, Academic fraud is a thing.
- tiborsaas 3y agoWhat's the point with academic fraud at this level? If it's fraud, then what did they expect other than career suicide?
- RivieraKid 3y agoPlease explain the benefit of faking the result of this paper and destroying your reputation.
- Koiwai 3y agohttps://en.wikipedia.org/wiki/Ranga_P._Dias#Controversy https://en.wikipedia.org/wiki/Ranga_P._Dias#Controversy https://en.wikipedia.org/wiki/Haruko_Obokata#STAP_cell_controversy https://en.wikipedia.org/wiki/Haruko_Obokata#STAP_cell_contr... I don't really have an explanation other than they're simply crazy.
- RivieraKid 3y agoIn other words, you agree with my original point. > And why fake it in the first place? I don't see the benefit.
- Koiwai 3y agoYou don't see, I don't see, but I believe they saw.
- foota 3y agoA fan?
- stronglikedan 3y agoIt would be very hard to fake the locking effect at 0:08 and 0:18 (and a few more times) with a fan.
- giarc 3y agoThey specifically act in a way to rule out fakes. For example they turn the magnet around to show that there are no small wires connecting the edges. They start and stop many times, they move in different directions. They knew the video would be watched with the default mind set that it is fake.
- chris_va 3y agoA moving magnetic field will move around any conductor, it doesn't have to be superconducting. A better video would be nice.
- stronglikedan 3y agoBut it wouldn't lock the target in place when they stop, which is what this video demonstrates very well. The conductor would move towards the magnet and try to stick to it.
- floxy 3y ago>The conductor would move towards the magnet and try to stick to it. No, only ferromagnetic material would behave like that. Copper foil will also move in a moving magnetic field, and won't be attracted to a stationary magnet.

- marcosdumay 3y agoPhotoshop. On reality, you would need a good computer with a large set of sound emitters just outside of the screen and a huge lot of tries. It would be a project for a small team and many months of work. Or maybe a few transparent wires and less photoshop. I do think the easiest way to fake a video like that would be to use a cool superconductor and change the atmosphere so nobody notices its temperature.
- XorNot 3y agoComplicated fakes wouldn't masquerade as scientific papers though. The FTL neutrino comes to mind, where it turned out to be a misconnected fiber optic cable - but everyone involved was genuine. The bits and pieces of this certainly look like little are being genuine, so the new question is what non-obvious mistake could they be making?
- 0cf8612b2e1e 3y agoThe FTL neutrino paper was not a fraud, but a genuine error. The publicity was practically, “This can’t be right, but here’s what we saw.”
- marcosdumay 3y agoIt's my impression, and it seems to be the consensus here that it is very unlikely that this is a mistake. This is either very real or completely fabricated. You don't have a piece of ceramic keeping its distance to a magnet by some unexpected phenomenon or measurement error. And given the easiness in reproducing the study, there doesn't seem to be any point in fabricating it.
- XorNot 3y agoThe main worry is whether we're dealing with wholly rational actors. People convince themselves they're seeing an effect, and then seemingly completely erratic things to try and prove it on the conviction that with just a bit more effort they'll get it for real. Like you'd question why someone would photoshop results[1] in a paper, because surely they'd have to realize they're fabricating data, but they go ahead and do it anyway. The videos are convincing but are they of what they really purport to show? I agree - what would be the point of fabricating it. But weirder things have happened in the breadth of human experience.

- bilsbie 3y agoSimply using a lower temperature with a known SC would be an easy way. He should hold it in his hand for 10 seconds before the test.
- lilgreenland 3y agoWell normal copper does this in presence of a strong magnet. I don't think we are seeing superconductivity, just regular copper Meissner effect. Super conductive would frame lock the copper. right?
- megaman821 3y agoEddy currents have a dampening effect. I am not expert enough to say we aren't seeing that here, but it looks different to me.
