Seeing as I do nothing with my day but read weird things on the internet, I'll tell you about a theory I've got about antigrav technology and how long the various governments of the world have had it.
Now this video from last year shows something called quantum trapping. Basically, what it boils down to, is that magnetic fields are affected by temperature. And you can manipulate it in the same way you would get a push from a magnet, to lock something into space.
A craft that supposedly has a coil of supercharged plasma (with some other special thing added into it) which is used to lock the thing into space. It also has three thrusters for movement.
Now UFO sightings of triangular craft with three lights have been going back decades. To the fifties at least.
The way the TRB-3B is supposed to operate reminds me of something else, that goes back a few decades more in time.
Die Glocke.
https://en.wikipedia.org/wiki/Die_Glocke Again, here we have the tale of the craft having a cylinder (well in this case two) filled with a mysterious liquid which was the essence of the machine. So probably after the war, due to Operation Paperclip - https://en.wikipedia.org/wiki/Operation_Paperclip - the Americans stole the technology from the Nazis.
That's just what I've found for recent history. There seems to be a gap from that point until way back till around pre biblical times with ancient Sanskrit texts talking about Vimanas. Now the wikipedia article on this is pretty sparse...there's lots of other sites (I can't judge how reputable they are) out there with diagrams of what these vimanas were supposed to be, and they all again seem to incorporate having some kind of ring built into it, then smaller points on the craft for steering populsion.
Any of you /boo/ lads seen any signs of this kind of tech show up at other points in history?
>>4271 Physicslad here. First of all I'd like to say cool video, these kinds of superconducting 'trains' are the kind of thing that many university departments like to show off but I've never seen one that levitates as high, or below the track before. It didn't really explain the physics very well, so I'll try to do that.
To address some of your points:
>is that magnetic fields are affected by temperature
While that's true indirectly, it's not really the best way to think about it. Temperature is a property of the material, which may affect is magnetic susceptibility which in turn affects the field passing through the material. In the case of superconductivity, there exists a critical temperature below which its resistance suddenly drops to 0 and its magnetic properties change discontinuously.
Most superconductors are perfectly diamagnetic, meaning that no magnetic flux can pass through. This leads to levitation, as the superconductor itself acts as a magnet of opposite orientation to the applied field in order to cancel out its internal flux. Therefore, the north pole of the external magnet repels the superconductor's north pole (or two south poles repel if the field is applied opposite).
However, the material in the video is a type II superconductor which, above a critical field strength, allows small vortices of flux to pass through the material at fixed points. The material is still mostly diamagnetic so it still levitates, but the fixed flux vortices also fix its position laterally.
>Is it such a stretch to imagine that extreme heat could do the same?
Actually, yes it is. Superconductivity is a low-temperature phenomenon - it can only occur below a critical temperature. Until the late 80s only materials with critical temperatures close to absolute zero had been discovered, though since then (so-called) high-temperature superconductors have been discovered at temperatures 90K and higher, achievable with liquid nitrogen. More recently, a superconductor at a temperature as high as 200K have been discovered (though admittedly at about a million times atmospheric pressure).
What is possible within our lifetimes is a room-temperature and pressure superconductor. Such a material would be revolutionary, allowing magnetic levitation and resistance-free current to be achieved in the home instead of the lab. However, the physics of high-temperature superconductors is not well understood theoretically and so finding such a material is a bit of a stab in the dark currently.

My university had some professors who were involved in research, but they were mostly sceptical about the possibility of ever developing practical room-temperature superconductors.
Most people know about the relationship between temperature and superconductivity, but superconductors have another serious hurdle to overcome, all superconductors can only be exposed to a certain amount of current and a certain amount of magnetic flux before it suddenly stops being a superconductor.
