Yes, I’ve taught Physics, but it was only a recent conversation with a Physics teacher after Trinity Sunday that the Baryon model of quarks came up as a model for the Trinity.
Quarks cannot exist alone. [It is possible for a quark and an antiquark to exist very briefly as a meson]. It takes three quarks to form a stable unit, a baryon. Protons and neutrons (the most stable hadrons – composite particles of quarks) are each composed of three quarks of different flavours. These are the primary building blocks of the Universe.
Discussions about The Blessed Trinity quickly tip into modalism and tritheism. Here is a model that might well be added to others doing the rounds, and it just might be a bit more robust than some. What do you think?
