Question About Gravity
Question
Hello Rabbi, this time I’m turning to you as a doctor,
I haven’t had a chance to see and check whether the following theory has been examined:
If, according to the theory, two charged particles exert a force on one another (attraction or repulsion, depending on the sign), is what we call gravity actually the effect of charges acting on one another, and since everything contains lots of charges, the attraction of the body with more charges is stronger?
I’m of course already raising the question: why would the attraction be greater than the repulsion? Seemingly there is the same amount of charge, but perhaps at most something else is missing that would explain it?
Answer
I didn’t understand the question. Are you talking about the force of gravity? It has no connection to electric charges. It is produced by mass, not by electric charge. Electric charge is the quantity that generates the electric force of attraction, while mass is the gravitational charge, that is, the quantity that generates gravitational attraction..
Discussion on Answer
No.
You probably know this, and it’s not exactly what I was thinking,
but it turns out they did try to unify the theory of electromagnetism with gravity, to find a unifying factor for them (UEG – Unified Electromagnetic Gravity).
Einstein also tried to find something like that.
At the moment they still don’t know exactly what the mechanism of attraction is. Is it some kind of particles? Is it some kind of wave?
They assume that mass attracts mass, but what is it in mass that causes attraction? Could it not be that the dependence on mass is because a large mass contains more charge?
