Well we already have to keep track of the size and shape of Earth. Go and read the SI Brochure from the BIPM. Local measurements by atomic clocks on Earth have to be weighted according to how far they are from a reference surface of equal gravitational potential. There's a publication named Circular T that comes out every 5 days. You don't need science fiction for this. * https://www.bipm.org/en/bipm-services/timescales/time-ftp/Ci... |
