It is really interesting how special and general relativity have stood up to such tests over the decades since the theories were first formulated. Putting special and general relativity on all the more sound footing, even in consideration of the possible developments of valid physics involving the unification of general relativity and quantum mechanics, will allow and promote the development of more theoretical physics and theoretical applied physics regarding concepts written into the laws of special and general relativity that were not foreseen by Einstein and the relativists that immediately followed Him.
