I’m not an expert in physics, but this seems like a misguided critique to me. My understanding is that physicists aren’t looking for “new” physics because they’re trying to upend established physics, but because they’re trying to reconcile “inconsistencies” in the standard model. Like reconciling quantum physics with general relativity. We need new physics because we know there are gaps in our current understanding of the universe. I haven’t heard about many attempts to disprove established physics. Theoretical physicists aren’t looking just trying to fill the gaps in the model.
