Levitation has been elevated from being pure science fiction to science fact, according to a study reported today by physicists.
In theory the discovery could be used to levitate a person
In earlier work the same team of theoretical physicists showed that invisibility cloaks are feasible.
Now, in another report that sounds like it comes out of the pages of a Harry Potter book, the University of St Andrews team has created an 'incredible levitation effects’ by engineering the force of nature which normally causes objects to stick together.
Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing this pheneomenon, known as the Casimir force, so that it repels instead of attracts.
Their discovery could ultimately lead to frictionless micro-machines with moving parts that levitate But they say that, in principle at least, the same effect could be used to levitate bigger objects too, even a person.
The Casimir force is a consequence of quantum mechanics, the theory that describes the world of atoms and subatomic particles that is not only the most successful theory of physics but also the most baffling.
The force is due to neither electrical charge or gravity, for example, but the fluctuations in all-pervasive energy fields in the intervening empty space between the objects and is one reason atoms stick together, also explaining a “dry glue” effect that enables a gecko to walk across a ceiling.
Now, using a special lens of a kind that has already been built, Prof Ulf Leonhardt and Dr Thomas Philbin report in the New Journal of Physics they can engineer the Casimir force to repel, rather than attact.
Because the Casimir force causes problems for nanotechnologists, who are trying to build electrical circuits and tiny mechanical devices on silicon chips, among other things, the team believes the feat could initially be used to stop tiny objects from sticking to each other.
Prof Leonhardt explained, “The Casimir force is the ultimate cause of friction in the nano-world, in particular in some microelectromechanical systems.
Such systems already play an important role - for example tiny mechanical devices which triggers a car airbag to inflate or those which power tiny 'lab on chip’ devices used for drugs testing or chemical analysis.
Micro or nano machines could run smoother and with less or no friction at all if one can manipulate the force.” Though it is possible to levitate objects as big as humans, scientists are a long way off developing the technology for such feats, said Dr Philbin.
The practicalities of designing the lens to do this are daunting but not impossible and levitation “could happen over quite a distance”.
Prof Leonhardt leads one of four teams - three of them in Britain - to have put forward a theory in a peer-reviewed journal to achieve invisibility by making light waves flow around an object - just as a river flows undisturbed around a smooth rock.

Few will listen,
Of the few who listen, fewer still will understand,
Understanding does not mean believe,
Of the handful who believe, most may not know what to do,
Those who even know, how many will actually do ?
And the rare ones who have done it.......
Need not listen to you anymore.

Stupid. A gecko has these incredibly thick finger prints that it can manipulate to squeeze small areas of friction. Every gecko owner knows that a glass aquarium will cause damage to these fingerprints, cutting them up...

I have been dreaming of levitation since I was 14. Maybe something happened to me. My memories are vague. I often dreamed of floating back to earth in a circular way. Once, while I was dancing on stage during a beauty pageant, I had an out-of-body experience. I merged with the spotlight and was unaware of what my body was doing. I know that I danced really well because I received a standing ovation; and when I lost the crown, most of the audience booed and left the stadium completely disgusted. My loss was so spectacular that the contest was taken away from the Lion's Club and deemed corrupt. I don't know what happened, but I believe I must have levitated at some point to have caused such a reaction.
I resumed flying and levitating in my thirties. I have written down everything in a 750 page book. You will never read it because the Jewish media doesn't publish goyim. |

Remember "soon" is relative! I wouldn't count on this keeping your skateboard aloft. However it's a pretty safe bet that your late 21st Century Wheelchair will probably be floating around on some sort of physical application of this principal. Fun eh? Or maybe rather than get bedsores in the nursing home, you're rotting flesh will be levitated above the mattress in the nursing home!
Have fun, but don't count on this being reality in time to use on a skateboard - especially if you're over 25 now. By the time it gets into common use - if indeed it ever does - you're going to be pushing 70 or better. Just hope you're still here. It might be worth hanging around just to see it!

It already is reality and has been since the movie was made. :) They said so in the DVD extras section of the movie, they said those things really are possible and could be made in toy stores but parents and other groups voted not to have it for safety reasons. I think someone else may have been responsible for wanting them to not be made but that's another story! :) But yup, hoverboards can really exist if they chose to make them.:) |

The Casimir Effect: Vacuum energy, dark energy, zero-point energy, anti-gravity energy?
What an amazing find!!!
[link to antwrp.gsfc.nasa.gov]
The attraction is known as the Casimir Effect, named for its discoverer, who, 50 years ago, was trying to understand why fluids like mayonnaise move so slowly. Today, evidence is accumulating that most of the energy density in the universe is in an unknown form dubbed dark energy. The form and genesis of dark energy is almost completely unknown, but postulated as related to vacuum fluctuations similar to the Casimir Effect but generated somehow by space itself. This vast and mysterious dark energy appears to gravitationally repel all matter and hence will likely cause the universe to expand forever. |

I see the teaching about our electromagnetic fields in the Gospel of Thomas.
...children who settled into an electromagnetic field/energy field, which is not theirs.
Some are experiencing and remembering the beginning, who will also know their ending. :)
Some insight from the Gospel of Thomas.
(18) The disciples said to Jesus, "Tell us how our end will be."
Jesus said, "Have you discovered, then, the beginning, that you look for the end? For where the beginning is, there will the end be. Blessed is he who will take his place in the beginning; he will know the end and will not experience death."
(21) Mary said to Jesus, "Whom are your disciples like?"
He said, "They are like children who have settled in a field which is not theirs. |

This is an excerpt from the site. Viktor S. Grebennikov discovered a phenomena in the tiny cavities made by insects that led to this..........
But I have no wings. I stand suspended in the air supported in my flight by a little flat, rectangular platform, which is slightly bigger than the seat of a chair. It has a pole with two handles onto which I hold and with whose help I navigate this device. Is this some science fiction? I wouldn't say so. The interrupted manuscript of this book had lied abandoned for two whole years because our generous, ancient nature had given me another something and again through my insect friends. As usual, it did it elegantly and inconspicuously, yet swiftly and convincingly. The thrill of discovery would not let go of me for two years, even though it seemed to me that I was mastering it at a break-neck speed. But it always happens this way. When your work is new and interesting, the time flies by at double its normal speed. The eye of the lake is already much closer. I can clearly see the highway beyond by now and the match boxes have grown wheels on them. The highway is about 8km away from the railway running parallel to it and if I look closer, I can see the power line poles on the light gray moat of the railway. It is time to turn some 20 degrees to the left. I can't be seen from the ground and not just because of the distance. I cast almost no shadow even in a very low flight. Yet, as I found out later, people sometimes see something where I am in the sky. I appear to them either as a light sphere, a disk, or something like a slanted cloud with sharp edges, which moves strangly according to them, not exactly the way a real cloud would. One person has observed a "flat, non-transparent square, about one hectare in size". Could it have been the optically enlarged little platform of my device? Most people see nothing at all though and I am quite pleased with it for the time being. I can't be too careful! Besides, I still haven't determined what my visibility or invisibility depended on. I must confess that I consciously avoid people when in flight and that I, for this very purpose, bypass all cities and towns and try to pass even the cross roads and footpaths at increased speed after making sure there is no one there. |

The research of Olaf Alexanderson and Henry Kjellson in Tibet
Swedish engineer Olaf Alexanderson detailed in the publication, Implosion No. 13, how some vibrations in the audio range will demonstrate to a physicist that a vibrating and condensed sound field can nullify the power of gravitation. Is this scientific knowledge the key to understanding how massive stones were made move and were levitated to accomplish amazing feats of engineering?
In the 1950s, a Swedish engineer named Henry Kjellson documented accounts from two travelers who each separately claimed to have witnessed acoustic levitation firsthand, in his book ‘The Lost Techniques’.
In one account, in 1969, a Swedish man named Dr. Jarl, a graduate of Oxford University in England and member of the English Scientific Society was invited by a former college friend to visit Tibet, where his friend was studying under a senior lama. Because of his longstanding friendship with his Tibetan friend, Dr Jarl was permitted to witness some of the hidden practices that were still taught in the region; traditions that had remained unchanged for many thousands of years. During a visit at a monastery to the southwest of Lhasa, Jarl witnessed a group of monks under tutelage of the lama move a stone that was (according to Jarl) 1.5 meters long, 1 meter high, and 1 meter wide. The stone was moved from a meadow to what appeared to be the opening of a cave over 250 meters above. In fact it wasn’t a cave, but a massive rock wall that the monks had been building.
Kjellerson is quoted as describing how the rocks were made to levitate thus:
“In the middle of the meadow, about 250 metres from the cliff, was a polished slab of rock with a bowl like cavity in the centre. The bowl had a diameter of one metre and a depth of 15 centimetres. A block of stone was manoeuvred into this cavity by Yak oxen. The block was one metre wide and one and one-half metres long. Then 19 musical instruments were set in an arc of 90 degrees at a distance of 63 metres from the stone slab. The radius of 63 metres was measured out accurately. The musical instruments consisted of 13 drums and six trumpets (Ragdons). Eight drums had a cross-section of one metre, and a length of one and one-half metres. Four drums were medium size with a cross-section of 0.7 metre and a length of one metre. The only small drum had a cross-section of 0.2 metres and a length of 0.3 metres. All the trumpets were the same size. They had a length of 3.12 metres and an opening of 0.3 metres.
The big drums and all the trumpets were fixed on mounts, which could be adjusted with staffs in the direction of the slab of stone. The big drums were made of 3 mm thick sheet iron, and had a weight of 150 kg. They were built in five sections. All the drums were open at one end, while the other end had a bottom of metal, on which the monks beat with big leather clubs. Behind each instrument was a row of monks. When the stone was in position the monk behind the small drum gave a signal to start the concert. The small drum had a very sharp sound, and could be heard even with the other instruments making a terrible din. All the monks were singing and chanting a prayer, slowly increasing the tempo of this unbelievable noise. During the first four minutes nothing happened, then as the speed of the drumming, and the noise, increased, the big stone block started to rock and sway, and suddenly it took off into the air with an increasing speed in the direction of the platform in front of the cave hole 250 metres high. After three minutes of ascent, it landed on the platform.”
Although Dr Jarl filmed this event, The English Scientific Society for which Dr Jarl was working allegedly confiscated the two films and declared them classified; as such they have never made their way into the public domain.
In the second account reported by Kjellson, an Austrian named Linauer stated that in the 1930s he was at a remote monastery in northern Tibet where he was shown two strange instruments that could produce weightlessness in stone. The first was a huge gong, 3.5 meters in diameter, made from an alloy of three different metals and which made an extremely low sound when struck.
According to Don Conreaux, a metaphysian and gong master, the essential key to the gong's force of resonance, and its effectiveness, is the complete submersion and saturation of a person or object in layer upon layer of tone-cell multiplication. The universal gong sound is based upon the musical principle that all tones of equal amplitude keep resonating, adding to themselves, to produce cumulative offspring, so to speak. This is a phenomenon unique to gongs
The second instrument was also composed of three different metals; but it was a half-oval shape like a mussel shell, and measured 2 meters long by 1 meter wide, with strings stretched lengthwise over its hollow surface. Linauer was informed that it created an inaudible resonance wave when the gong was struck. The two instruments were used with a pair of large screens, positioned so as to form a triangular configuration. The gong was struck with a large beater to produce a series of brief, low-frequency sound waves; a monk was then able to lift a heavy stone block with just one hand. According to Linauer, the monks told him that this was how their ancestors had built protective walls around Tibet, and that such devices could also disintegrate physical matter.

The Casimir effect is so weak that it could never be exploited to levitate anything heavier than an atom. This is old physics familiar to any graduate student in physics. As for 'explaining' human levitation, that is the typical hyperbole one expects from science journalists who love to dupe people into thinking that 'science' has explained a paranormal mystery. |
