Experiments in sound or acoustic levitation are common and ongoing. Dozens of researchers have managed to use sound waves to levitate and move tiny particles and liquid droplets. Multiple vibrating plates are used to create different frequencies and move an acoustic field with particles trapped inside. The techniques developed have not been used to lift heavy or large objects. Twenty-first century scientists do not yet know if such a thing is possible. But there have been breakthroughs, some of which are significant enough to suggest that large-scale acoustic levitation may some day be possible.

These orbs of liquid aren’t magically levitating: they’re hovering on the power of sound waves.

In two experiments, scientist have successfully levitated lightweight polystyrene balls greater in size than the wavelengths used to elevate them, which represents an important step forward in the management of the force of concentrated sound. One of these experiments, carried out by a joint team of researchers in the UK and Brazil in 2016, lifted a 50-millimeter polystyrene ball several centimeters off the ground, where it remained suspended for as long as the sound waves were generated. Just one year later, another group of researchers working out of the University of Bristol successfully levitated a polystyrene ball of two centimeters in diameter.

One theory credits the building of the pyramids and other megalithic monuments to acoustic levitation. No first-hand accounts exist, but later written testimony provides some intriguing and suggestive clues. Abul Hasan Ali Al-Masudi, an Arab historian from the 10th century A.D., wrote about ancient Egypt and the methods he alleges they used to move massive stones, including those used to build the pyramids . He 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.

Outside of this written testimony, which is open to interpretation, there is no direct evidence to suggest the pyramids were constructed by acoustic levitation. But the Great Pyramid of Giza does possess some extraordinary acoustic properties, demonstrating the capacity to dramatically amplify sounds generated at certain frequencies. The Egyptians who built the pyramids on the Giza plateau clearly knew a lot about sound and knew how it could be used to produce powerful effects—possibly including levitation.

Another creation that some have credited to sonic or acoustic levitation is the Coral Castle , which is located in southeastern Florida, not far from the city of Miami. The Coral Castle is a sprawling stone city built by Latvian-American immigrant Edward Leedskalnin between the years 1923 and 1951. The Coral Castle complex is constructed from nearly 1,000 tons of rock, which Leedskalnin somehow cut, shaped, lifted and maneuvered into place all by himself.

Leedskalnin refused to allow visitors or observers onsite while he was working, so there are no eyewitness accounts detailing his construction methods. There were no reports of mysterious sounds coming from the vicinity of the Coral Castle during the construction phase, but sonic levitation generally relies on the use of sound frequencies that are inaudible to humans.

In his writings and conversations, Leedskalnin never specifically identified sound as a key factor in his work. But it is known that he had an interest in radio and possessed a range of radio equipment, which he used for unknown purposes. Leedskalnin at one point told someone he knew how to tune in to “the music of the stars,” a reference that could have either literal or metaphorical connotations. In explaining his amazing feats, the perpetually enigmatic Leedskalnin proclaimed the following:

“I have discovered the secrets of the pyramids and have found out how the Egyptians and the ancient builders in Peru, Yucutan and Asia, with only primitive tools, raised and set in place blocks of stone weighing many tons!”

There is an implication here that somehow these ancient masters had a developed a method for overcoming the force of gravity. Just exactly how Leedskalnin would have discovered the secrets of the ancients is unknown, but there are reports that he was a practicing Freemason who may have been exposed to such knowledge through his contacts in that organization.
