instead of four parameters.
Why would that be a harder problem? In the case that you get a zero parameter, you could inflate it by some epsilon and the solution would basically be the same.
- Sesse__ 2y agoThey also, effectively, fit information in the indexes of the parameters. I.e., _which_ of the parameters are nonzero carries real information. In a sense, they have done their fitting using nine parameters, of which five are zero.
- aqme28 2y agoI didn’t read enough to catch that. How the heck did they justify that?

Add an epsilon worth of torsion to GR and you don't get almost-GR, you get a qualitatively different theory in which potentially arbitrarily large violations of the equivalence principle are possible.
- aqme28 2y agoThat's not relevant here though, because their function is continuous and they're fitting to an arbitrary shape. It's not a "perfect science," so there would be wiggle room.
