Researchers have discovered that sound waves can make any object levitate

A group of researchers at Columbia University unveiled the findings of an experiment indicating that sound waves can carry gravitational mass in February 2019. During the experiment, scientists discovered that sound waves can produce a small gravitational field.

“Calculations show that sound waves have a bit of negative mass, which means that when they pass through a gravitational field like Earth’s, their path curves upwards. According to the story, “Scientists discovered that sound waves emit a small gravitational field.”

For a long time, scientists believed that sound waves could only transmit energy, not mass. According to Phys.org, the researchers found data that contradicted their previous results.

According to the researchers, sound waves traveling through superfluid helium have a small amount of mass. They proved this theoretically, but they didn’t measure the amount of mass carried by the sound wave.

They found that as phonons (quasiparticles) interact with the gravitational field, they impart mass to the substance they pass through. The scientists show that the same results apply to most of the components in their current investigation.

Methods for testing the research results in the real world were proposed by the researchers. One option is to use gravity-sensing sensors to study earthquakes. As the earthquake transmits sound around the world, the devices can detect “billions of kilograms of mass” carried by the sound.

In the year 2020, scientists created an algorithm to detect seismic impulses that cause gravity to deform, changing the density of rocks for a brief period of time. Light-speed signals are sent out by these fluctuations in gravity, allowing earthquakes to be detected even before they cause damage.

The revelation that phonons have negative mass and, as a result, negative gravity was raised by the same group of scientists a year earlier.

Michio Kaku, co-founder of string theory, adds, “It turns out that under some conditions, sound waves can actually start to rise instead of fall.” And this anomaly appears to be in line with physical laws, as certain vibrations can actually fall upwards rather than downwards.

This discovery, according to scholars of ancient civilizations, indicates how ancient humans transported large stones. It is likely that they used sound waves and vibrations to do this.

According to legend, sound played a role in the creation of great structures like the pyramids in Egypt, which were built using sound of exact frequency.

Scientists believe that one day they will be able to understand the mystery of sound waves and, as a result, design a system capable of moving massive objects.
