Last century, many physics equations were one-liners, like E=mc2, but the equations of string theory now fill pages if not books. As we gather knowledge from the tree of nature, perhaps all the low-hanging fruit of one-line equations have been picked, and the use of machine learning for over three decades hasn’t changed this. Meanwhile on the theoretical front, the result has been one wrong prediction after another, for as one physicist notes:
Ten thousand wrong predictions sounds dramatic but its actually an underestimate… all the extra dimensions … all the pretty symmetry groups, all the new particles … They were all wrong. Even if the LHC finds something new in the data that is yet to come, we already know that the theorist’s guesses did not work out. Not. A. Single. One. How much more evidence do they need that their methods are not working?” (Hossenfelder, 2018).
Fifty years without progress in physics is unprecedented so its time for a change. The change proposed in this section is to stop spinning what Hossenfelder calls theory-tales and re-develop theory from the data ground up.
