-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 consider one final thought experiment: you mentioned super conductors and natural magnets. before we understood electromagnetism, a natural magnet was the strongest magnetic force we would encounter. with super conducting electromagnets, we can generate magnetic fields many orders of magnitude stronger than have ever existed on earth! truly magical :) right now we only know natural gravity : and it's exceptionally weak! imagine being able to create gravitational force, in abundance... warp drive becomes reality :) best regards, -----BEGIN PGP SIGNATURE----- iNUEAREKAH0WIQRBwSuMMH1+IZiqV4FlqEfnwrk4DAUCYET9ol8UgAAAAAAuAChp c3N1ZXItZnByQG5vdGF0aW9ucy5vcGVucGdwLmZpZnRoaG9yc2VtYW4ubmV0NDFD MTJCOEMzMDdEN0UyMTk4QUE1NzgxNjVBODQ3RTdDMkI5MzgwQwAKCRBlqEfnwrk4 DNCYAPsEDVi3RkM6sea4ull0uqaeKevLSbpxIBkzr9wYzmq55wD+PE3j/gbPTi3A 5aHNsuZx/8k7dRMt2lBhO1C4gJproo8= =NpJM -----END PGP SIGNATURE-----
