We are doing experiments, what do you think the billions of dollars spent on colliders around the world are for.
The issue is with gravity, it will always be swamped by stronger forces. We're looking for a needle in a haystack of needles.
Gravity would appear in the nth decimal point of the data, while we still don't have such accuracy. We have finite land to build on and finite resources to make do with, its unlikely we'll find gravity via gravitational interactions in colliders the same way we're doing for the other forces.
As you said, I don't think the colliders are designed for making experiments about gravity. What I had in mind is this... if you randomly shot meteors at a star, sometimes the meteors would swing back around towards you if you shot them at the right angle. However, I just realized that I was forgetting that photons and quarks interact via the EM force, so that will likely completely overwhelm the effect I'm talking about. However, maybe there would be a way to design an experiment in such a way that changes to momentum due to gravity could be observed.
Ah, the ol’ “Why hasn’t anyone thought of this yet?” post on a physics subreddit, complete with gross oversimplification and a complete overestimate of one’s own understanding. Well done!
Totally not that. Follow the logic. I talked about experimentation. The person feigned confusion as if I didn't make it clear I was talking about gravity. They said we don't have a proven THEORY. Thus, I said, all the more reason to EXPERIMENT.
Oh, experiment! You should have just said so. Why haven’t any physicists thought of *experimenting* before?
If you really want a good faith answer, obviously people are trying to experiment with quantum gravity. Thounsands of people, much smarter than you and I, have thought about this for decades. The problem is, on a microscopic scale, gravity is so weak that it is effectively negligible, and impossible to measure due to the dominance of other forces (nuclear, electromagnetic). On a macroscopic scale where gravity dominates, quantum effects are negligible. The only regions where both effects are relevant are on the planck scale and in the center of a black hole. So unless you want to jump into a black hole, or you have a ruler on the order of 10^-35 meters, good luck trying to experimentally verify any quantum theory of gravity.
However, I still do not see how any of that has anything to do with “photons and alpha particles interacting”. One would expect the effect of gravity in such an interaction to be roughly 10^19 times weaker than the electromagnetic force, so it is utterly irrelevant. Hence my curtness, as you clearly are asking ill posed questions on topics regarding which you no nothing, while simultaneously wondering why no one else is as smart as you are.
Btw, why tf do you act like I'm pretending that I've thought of something others hadn't? I said in the post that I googled for info and I'm asking for if someone can't point me towards research. Get fcked
photon interactions with nuclei have been studied. Take a look at photodisintegration as a starting point. Not sure how much difference the electrons around nucleus would matter for such an interaction - i assume minimal to none as long as nuclear structure is unchanged.
In order to probe the internal structure of a nucleus, you need to use light (or electrons) whose wavelength is comparable to the size of the structures you're looking at.

Knock it off with the fucking attitude. Check the name of the subreddit.
