Are you talking about particle collisions in curved spacetime?

I do not know.

I don't know anything about QFT and am currently studying general relativity.

If you don't know what question you're asking how can anyone answer it?I do not know.

I am studying the Schwarzschild metric and I have read that if you get too close you fall into the object in question, I thought that this could be related to the fact that particles can be absorbed by other particles. Are these two concepts related? Should I study QFT first?

Not really. One is the theory of gravity; the other is the quantum theory of particle collisions. Particle collisions are not modeled as a gravitational process!I am studying the Schwarzschild metric and I have read that if you get too close you fall into the object in question, I thought that this could be related to the fact that particles can be absorbed by other particles. Are these two concepts related?

QFT is more advanced than GR in my opinion.Should I study QFT first?

I went to see a psychic. She asked me "what seems to be the problem." I replied "you tell me!"If you don't know what question you're asking how can anyone answer it?

From which source? Textbook(s)? Formal Course? Pop-sci fluff?I am studying the Schwarzschild metric

Since you mentioned "curiosity", I'll risk telling you that they're "related" only in a vague sense that in the vicinity of the Schwarzschild horizon there's a phenomenon called Hawking Radiation. This is an advanced topic, requiring knowledge of QFT in Curved Spacetime (which is far more difficult that ordinary QFT -- which is itself one of the most difficult areas of theoretical physics).and I have read that if you get too close you fall into the object in question, I thought that this could be related to the fact that particles can be absorbed by other particles. Are these two concepts related?

Yes, but try advanced QM first (see my signature line), then introductory QFT, then advanced QFT, then try QFT in curved spacetime. That should keep you gainfully occupied for many years.Should I study QFT first?
