Bizarre Source of “Negative Gravity” Surrounds Us, Physicists Say

Newton’s laws of motion and gravity still govern the macro world as we know it. Accordingly, every object that goes up must eventually drop down, under the gravity attraction. However, the physicists at the Columbia University came up with a study that estimates that negative-mass particles go up instead of coming down under the same gravitational forces as in Newton’s laws. Even more, such bizarre source of “negative gravity” surrounds us.

The study did not focus on God-knows-what exotic quantic particles but on the common phonons, those particles of sound that we hear and generate day-by-day. According to the physicists, the phonons travel around us, as we know it already, beating the gravity attraction forces.

The whole research started from a bizarre paradox the scientists pictured. Namely, the physicists thought, what if sound waves have a mass, more specifically, a negative mass that can generate a “negative gravity” field that helps phonons go up instead of coming down under the forces of Newton’s gravity.

Could these phonons indeed possess negative mass that generates the bizarre “negative gravity” field?

The before-mentioned study is just a theory for the moment, and no practical experiment has been conducted yet to prove this hypothesis regarding phonons. However, the scientists already found the negative mass particles do exist, and they are opposing a specific force.

So, if particles with negative mass exist, then would the phonons be such particles?

The general theory is that the phonons do not carry a mass and that’s why they can travel without being affected by the gravity. But previous research in this direction conducted by the new study’s leading author, Alberto Nicolis, come up with some experimental proof that photons might indeed be a source of “negative gravity.”

According to that previous study, in an environment with no resistance and at a temperature close to absolute zero, phonons were observed moving upwards, against the gravity attraction.

“In a gravitational field phonons slowly accelerate in the opposite direction that you would expect, say, a brick to fall,” also said Rafael Krichevsky, one of the study’s co-authors.

In conclusion, the sound waves’ phonons might indeed possess a negative mass.
