In other sciences we call an invariant a catalyst.

Thanks to Prof. Greene for co- founding World Science Uni!

Invariants could also include light as Einsteins calculated speed and spacetime itself.

The inclusion of spacetime as invariant prevents scientific backsliding into Euclidean or Newtonian science.

Hopefully the Prof. Greene books are in the library.

What happens to light as Tesla 3x speed as an invariant? It lodes invariant status, as it slows down to Einsteinian speed. This may be due to dark matter, but more probable as due to dark energy – 26% vs. 70%- or so.
