I agree, or actually I assume that the disagreement is only about words. I would not call it new physics, if, for example, we have to couple quantum fields to GR in a not straightforward way, so in the case were we already know all the parts but not the specific combination of the parts. I would only call it new physics if we have to rewrite basic textbooks.
- AnimalMuppet 11y agoIf this showed us how to couple quantum fields to GR, that would be pretty good. Personally, I would consider that "new physics", given how unclear it is how to do so at the moment. If doing so doesn't significantly change either GR or quantum, however (and so the basic texts are still valid), I could go with your view.
