I agree wityh Harvey. In fact, I am quite amused at how very disparate abstractions (read assumptions) can lead to the same correct theories.

My favorite example, is the QED derivation of Feymann which assumes that only particles exist, but that anti-particles (positrons) travel back from the future to cancel the otherwise infinities of the electron in Quantum ElectroDynamics.

Another is Einstein's General Relativity which attributes gravitational attraction to space-time geometrical distortion.

The Standard Theory provides an alternative abstraction to both QED and GR.

So physics does not tell us what reality is. It just tells us what equations agree with experiment and that many different fundamental theories can be dual- i.e.,fundamentally different abstractions can derive the same equations. The conclusion, in agreement with Harvey I believe, is that correct equations do not make correct assumptions or abstractions, they make myths.

My tendency in such cases is to look at scripture to decide which myths are more likely to be real, as I have often stated in past posts.
