I te tau 1892, i whakaarohia e Hendrik Lorentz he whakarerekētanga o te tauira a Fresnel, kei reira te aether e tino tu ana. I angitu ia ki te whakaputa i te taurangi tohatoha a Fresnel hei hua o te taunekeneke i waenga i te wai e neke ana me te aether kaore i tohaina. I kitea hoki e ia ka taea te whakawhiti mai i tetahi ki tetahi atu anga tohutoro ma te whakamahi i te taurangi wa awhina i kiia e ia he waa rohe: Patai: He aha te ingoa o te waa awhina?
