Nordström's theories arose at a time when several leading physicists, including Nordström in Helsinki, Max Abraham in Milan, Gustav Mie in Greifswald, Germany, and Albert Einstein in Prague, were all trying to create competing relativistic theories of gravitation.
However, Preston's thoughts were entirely based on classical, non-relativistic physics and cannot be compared with Albert Einstein's mass–energy equivalence, which is a consequence of special relativity.
