Dave,
What you said is exactly what was described by H. G. Wells in his book. I'm now locating this book within the library under the children section. Be back shortly. About the symmetry, it is spatial symmetry or switching of space coordinates, you are there, I'm here, now we switched, I'm there, you are here. Time independence: [∂E(g)]²=[∂F(a)×∂r(a)]·[∂F(b)×∂r(b)] and Mass independence: ¶a(t)·¶r(t)=c² |
