IDK if this is a actual supportable theory or just something someone pulled out of her backside but…
Is there some type of theory that states that a particle’s probability of interaction with other matter is inversely proportional to the density of nearby matter (or due to gravity which is cause by the former).
Example: A neutrino rarely interacts with anything because we are measuring it’s interaction probability on earth (typically flies though the entire earth, out the other side and continues on its way) , but it would be much more likely to interact with any matter it comes in contact with in deep interstellar space, that say it hit a small piece of dust and would be much more likely to interact with that then the entire earth.
If it is exists can someone point me in a direction on it?
