If it does, is there a way to calculate what the force of a single photon would be if it were acting in 3 dimensions?
jcatom said:I've seen in several places that gravitation as a fundamental force is weak compared to electromagnetism. If gravity=1 then EM=10^36.
What I'm asking is: if EM is linear, could there be a calculation to find what it's strength...or potential would be if it were like gravity and acting in 3 spatial dimensions at once?
jcatom said:I know that it is considered to be everywhere at once until it is detected. But when it is detected it is at a single point.
The question is if it could be detected at all points on the imaginary spherical plane at once (which I know it can't) what would the difference in strength be as compared to the single point which we detect in reality?
jcatom said:More than they would attract through gravitation?
jcatom said:Right, wave-particle duality. I've read about the double-slit experiments and how a single photon can even interfere with itself when it is in a wavelike state.
My question is about that moment/point of interaction--the collapse of the wave-function. When there is suddenly a single photon, does that interaction take place in a single spatial dimension? The photon has no mass so it's hard to see how it could be more than that. I'm leaving the time dimension out right now.
jcatom said:I don't mind being wrong, but I'm not 'obsessed' with anything either. Nor do I think that disparaging remarks towards people here engender respect. 'Obsession' almost always carries a negative connotation.
Wouldn't a massive particle of the smallest size exert a gravitational 'pull' (which I know is not the right word) on every other massive particle around it? Gravity in the way that Einstein described it is a curvature of spacetime in 3D--not really like the dumbed-down 2D representation of a grid that has a hole in the middle that we often see.
ZapperZ said:Yes, but what does that have anything to do with the discussion here? You asked if a single photon "acts" in 1D. I've given you an example (non-head on collision) in which one can see that the dynamics can't be confined to 1D. Doesn't that already answer your question?
So I am no longer sure what it is that you're trying to get at, since you already were given the answer. It may not be the answer you want, but Nature often doesn't care about what we want.
Zz.
jcatom said:I was responding to this question "Can you point out any physics in which the spatial dimensions plays a role in such interactions."
Certainly didn't expect such animosity or condescension. Thanks I guess.
jcatom said:Gravitation occurs in 3 spatial dimensions. Does electromagnetism occur in only 1 spatial dimension?
I will and thanks again. I'll also do better about quoting so that the direction of my response is more obvious.Keep thinking.

Thanks for the response.We don’t know the exact nature of gravitation, but if we image some photon or quantized unit of gravitation, that case would be the same as for your 1 dimensional light photon (i.e. it would not diminish with distance).
jcatom said:The difference I see is that a photon is in some sense everywhere at once until it interacts with something. Upon interaction the wavelike photon is suddenly in one specific place in time and the dispersed energy is concentrated at that point.
Gravity doesn't seem to be like this at all. I know that there is the theoretical graviton, but nobody has figured that out. Would gravity suddenly be at a single point in time when it interacts with a massive body, taking the energy (or whatever the best term is) from a dispersed area and collapsing down to a single point in time?
