I Schwarzschild Metric & Particle Absorption

[accdd]

The Schwarzschild metric implies a potential different from that of Newtonian gravity. Is there a relationship between it and the process by which particles can be absorbed by other particles?

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?

Curiosity.
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!

Should I study QFT first?

QFT is more advanced than GR in my opinion.

I went to see a psychic. She asked me "what seems to be the problem." I replied "you tell me!"

No.

From which source? Textbook(s)? Formal Course? Pop-sci fluff?

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).

Should I study QFT first?

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.
