Pairs of Planck-mass drops of superfluid helium coated by electrons (i.e., “Millikandrops”), when levitated in a superconducting magnetic trap, can be efficient quantutransducers between electromagnetic (EM) and gravitational (GR) radiation. This leato the possibility of a Hertz-like experiment, in which EM waves are converted at tsource into GR ( Read more... )
