Levitation using sound is now real and not a Sci-Fi subject, at least on a small scale for now. Recently, researchers have described using acoustic levitation with sound waves to levitate tiny plastic particles. Rather than remaining stationary, as in previous studies, the beads float, spin, and form clumps as the sound waves act as a “kind of sticky glue.”
The researchers from the University of Chicago and the University of Bath used a loudspeaker to levitate the plastic particles in a clear box. Then, the speaker generated a standing wave, remaining stationary.
“A standing wave, also called stationary wave, [is a] combination of two waves moving in opposite directions, each having the same amplitude and frequency,” writes Britannica. “The phenomenon is the result of interference; that is, when waves are superimposed, their energies are either added together or canceled out.”
As the researchers generated the standing wave, the particles formed a floating disc of particles held together by the “weak attraction” the sound waves generate. Thus, it’s reminiscent of gravitational attraction.
As the particles spin, the centrifugal force breaks apart the cluster. However, the fragments eventually return to a single circular disk again.
By observing how the tiny particles behave, the scientists can gain insights into how vastly larger celestial bodies, such as asteroids, move, Popular Science writes. On the other hand, it could also relate to much smaller things, like atomic nuclei.

Ultrasound Waves Create Tactile Talking Holograms
Already, polystyrene beads have been used to create 3D holograms, which can “talk” and interact with onlookers. Not only that, but you can also “feel” the holograms with tactile touch. For example, you could feel the flutter of a holographic butterfly’s wings (see video below).
First, a tiny 2mm- bead floats at high-speed in mid-air, trapped in a pocket of low-pressure air as a series of ultrasonic speaker arrays manipulate it. By moving at speeds around 20mph, one can’t see the bead. Meanwhile, it traces out 3D shapes while LED lights shine on it. While the speakers make the bead float, they can also make the bead vibrate to produce a clearly audible sound.
“Because the images are created in 3D space, they can be viewed from any angle. And by careful control of the ultrasonic field, the scientists can make objects speak or add sound effects and musical accompaniments to the animated images. Further manipulation of the sound field enables users to interact with the objects and even feel them in their hands,” writes the Guardian.
Along with beautiful displays, the levitation tech could lead to much more. For example, “it could transform 3D printing by building objects from tiny droplets of different materials that are levitated and dropped into place.” Therefore, sound could be used to construct buildings, maybe a pyramid?

Previous Acoustic Levitation Attempts
Two prior studies from 2016 had applied acoustic waves to make larger polystyrene balls float in one place. At that time, a 2-inch ball was one of the largest objects levitated using sound. One team of researchers aligned three ultrasonic transducers in a tripod shape. However, the team which levitated the 2-inch ball created a standing sound wave using a single ultrasonic transducer with a sound reflector.
Ancient Knowledge of Acoustic Levitation?
One day, it may be possible to levitate much larger objects with sound. Maybe, we could levitate ourselves across the sky via sound technology.
Of course, theories abound about whether ancient people had advanced knowledge on the subject. For example, an Arab historian from the 10th century AD, Abul Hasan Ali Al-Masudi, alleged the Egyptians may have used sound to levitate massive stones.
“[Al-Masudi] claimed that a magic papyrus imprinted with symbols was placed under each stone, after which a metal rod was struck against the stone to initiate the levitation process. According to Al-Masudi, the stone would be guided along a fenced path with metal poles placed on each side. Some believe these poles could have been used to create high-frequency sound vibrations, which would have been responsible for creating the levitation effects,” wrote Ancient Origins.

Sound at Specific Frequencies
This is just one example from ancient history suggesting people could move large stones using sound. However, moving things would be only one use, and some say that sounds at certain frequencies could have been used for healing purposes and more, even to open portals.
For example, chambers inside the Hypogeum of Hal Saflieni on the island of Malta resonate with precise frequencies around 110 Hz.
According to research, listening to this frequency deactivated the language center in the brain and turned on the right side.
Likewise, chambers in the Great Pyramid of Giza can dramatically amplify sounds generated at certain frequencies.
More recently, in 2006, Alexander Golod constructed 17 fiberglass pyramids in Russia, claiming the structures themselves have healing powers. At the time, the tallest was 132 feet.
“Anyone in the vicinity of this pyramid,” he says, “will not become ill with cancer, AIDS, Alzheimers disease, or other sicknesses,” Golod claimed.
According to Golod, “the space around us has become distorted with the passage of time, leading to an increase in the incidence of disease, natural calamities and social unrest. He says the pyramids help restore the natural form of distorted space,” states AP (see video below).

Profound Potential for Sound/Gravity Wave Tech
Generally, scientists would rebuff claims of pyramids healing people, but there are already real-world applications for sound in healing. For example, scientists have used acoustic signals and cymatics to generate heart tissue. Thus, sound is part of the “medicine of the future” already, as Edgar Cayce once said.
Also, wave technology could lead to incredible advances, not just sound waves. For example, a podcast with UAP experiencer and author, former US Naval service member Matthew Roberts recently suggested something compelling about gravity and waves. (Roberts was aboard the USS Theodore Roosevelt when they captured the famous Gimbal and GoFast UAP footage.)
After attempting to study the UAP method of propulsion, Roberts, a cryptologist, determined the craft used antigravity. As a cryptologist, he knew “quite a bit about signals” and how they “travel through the air.”
“I knew that signals travel in wave form,” Roberts said.
One day, driving home from work, Roberts listened to an NPR story about scientists who found that gravity exists in waves.
“…They were able to measure these waves of gravity as these two distant black holes were colliding. And I thought to myself, ‘That’s how signals work too.’ And I knew that if you broadcast in the same frequency as an unwanted signal, you could block that signal. And, so I thought, well, you could do that with gravity then, too, technically…and you could block that unwanted gravity signal. So it would have to be anti-gravitic technology.”
Thus, after thinking it through, Roberts concluded the UAP appearing near the ship were possibly using antigravity tech in this way. Certainly, wave tech will have profound implications for the future – a universe of Sci-Fi levitation (and antigravity?) made real.
