The Quantum Field Theory on Which the Everyday World Supervenes

Sean M. Carroll

Abstract

Effective Field Theory (EFT) is the successful paradigm underlying modern theoretical physics, including the "Core Theory" of the Standard Model of particle physics plus Einstein's general relativity. I will argue that EFT grants us a unique insight: each EFT model comes with a built-in specification of its domain of applicability. Hence, once a model is tested within some domain (of energies and interaction strengths), we can be confident that it will continue to be accurate within that domain. Currently, the Core Theory has been tested in regimes that include all of the energy scales relevant to the physics of everyday life (biology, chemistry, technology, etc.). Therefore, we have reason to be confident that the laws of physics underlying the phenomena of everyday life are completely known.

    • I reject panpsychism on the grounds of the Standard Model. There are no possible fields at the energy levels we've explored that could have an effect such as panpsychism claims (and fields at any other energy levels couldn't have such an effect). Sean Carroll published a paper…

    • We do have a theory of physics which is likely to be able to cover all the phenomena of biology[1], but that is beside the point. If you think that human behavior cannot be reduced to equations, then you think it cannot be predicted mathematically. I can only interpret this as a…
