Einstein's equivalence principle has three further implications besides affecting time: T-L-M-Ch theorem (“Telemach”)

General relativity is notoriously difficult to interpret. A "return to the mothers" is proposed to better understand the gothic-R theorem of the Schwarzschild metric of general relativity. It is shown that the new finding is already implicit in Einstein's equivalence principle of 1907 and hence in special relativity (with acceleration included). The TeLeMaCh theorem, named onomatopoetically after Telemachus, is bound to transform metrology if correct.
