@AstroKatie After reading the book, I had a question on the Higgs field (if it’s dumb feel free to disregard).
If you were an entity that developed solely using the Higgs field as your energy receptor/identifier (as opposed to photons), would photons appear as dark matter?

Hm trying to imagine this but I think no because I don’t know how you’d detect photons at all. (Like, we can’t see DM but we detect its gravity; not sure what the equivalent would be here)

In my mind it would be “seeing” (for lack of a better word) the world through gravitational/mass interactions, and then knowing stuff like thermal reactions/radiation occur but being unable to detect the thing actually causing it (similar to the effects we “see” from dark matter)

Like, does that make sense in any way?

Yeah! I see what you’re saying now. Basically I think you can accomplish the same kind of thing by saying what if we could only “see” via gravity and we saw that there were these weird disk-shaped things and compact planets and stuff and photons had to exist to explain that

(Because you can’t get disks and solid planets without electromagnetic interactions to let stuff lose angular momentum and “collapse”)

Right, that’s what I was getting at. If that’s the case, do you think it’s still possible to write an e=mc2 type equation without being able to detect photons directly?

Maybe? Because c isn’t just the speed of light, it’s also the speed of gravitational waves; it’s the speed of causality. But I don’t know how you would do experiments of any kind if you couldn’t interact with things electromagnetically

Ok cool, thanks for the responses, I just thought it was interesting to think about how many of our base assumptions are predicated on being able to interact with photons, and how the Higgs field is fundamentally (as far as we know) unable to do so. It struck me as similar to DM.
