Abstract |
Testing the upper limit of the photon mass can be realised through the modified Ampere's law in solar wind, which we have realised with the Cluster spacecraft [2], or from frequency dependent group velocities with the proposed nanosatellites swarms operating in a new radio astronomy window, 10 KHz – 10 MHz, [1]. Cluster and other upper limits appear in the Particle Data Group annual report. Finally, light frequency invariance in vacuum could be tested with the LISA interferometer. Incidentally, we ponder whether LISA could test the upper limit of the Hubble-Humason cosmological constant at small scale. [1] Bentum M.J., Bonetti L., Spallicci A.D.A.M., 2017. Adv. Sp.
