Sound waves can carry matter.

Have you ever imagined that sound waves can carry stuff? Of course, we’ve seen this happen in science fiction, but never have we witnessed it happen in the real world.

Researchers have recently demonstrated how particles of sound have the ability to carry mass.

Furthermore, this means that these particles can create their gravitational fields.

In their paper published in the journal Physical Review Letters, Angelo Esposito, Rafael Krichevsky, and Alberto Nicolis used effective field theory techniques to confirm a discovery made by researchers last year, attempting to measure mass carried using sound waves.   […]
