As part of my daily routine, I trend to spend some time reading high tech stuff in order to keep my brain alive. So eventually, I end up reading some odd ideas and as usual, after all been me, I think about it and their realistic possibilities.
The physics principle:
Following quantum mechanics math we have discovered the possibilities of a Bose-Einstein matter state named Superfluidity. Just as a superconductor is able to conduct an electrical current with no resistance (no Joule effect over the work done by the electrons) a superfluid is able to flow with no friction. As the superfluid is flowing, since it will flow with no friction the flow speed will increase gradually and eventually the increase on speed will be exponential.
At certain point, this superfluid will reach relativistic speed (57.7% of the speed of light to be exact), which means it will be able to bend the space-time plane.
The idea is to keep a superfluid running forever as theory says; but in order to keep the fluid contained the need of a toroidal type device is definitely a must. This way we warranty that the fluid will be running in a circle increasing the speed as explained before.
Anyways, the only way to control the vortex created by the fluid movement without interfering with the fluidity will be if the fluid itself present ferrous-magnetic properties and the container an electromagnetic toroid. The ability of creating a ferromagnetic super-fluid is the key part and I'm 100% sure there are people working on this fluid as I type this words.
Assuming such a fluid exist, we have the technology to build a toroidal shaped propulsion system that will feed on anti gravitational forces. Now... let me pop some questions.
why is it that the typical shape of UFO's is a flying disc?
Have I discovered something?... does UFO's use this kind of anti-gravitational propulsion system?
