# Would protons in a straight line ever break their alignment? [closed]

Let any amount of arbitrarily spaced protons appear along a line segment of length $$x$$ in an otherwise empty universe at $$t+0$$

What mechanism, if any, could cause the breaking of said alignment between $$t+\large\frac{x}{c}$$ & $$t+\small\infty$$?

• The Heisenberg Uncertainty Principle will make that difficult. – PM 2Ring Apr 25 '19 at 14:20
• If you allow quantum effects, then the uncertainty principle. – Lewis Miller Apr 25 '19 at 14:21
• What's the point of your question? – Bill N Apr 25 '19 at 14:52
• Wouldn't knowing that the position of each proton is still in the exact alinement after they each had an initial effect on each other negate any uncertainty about their velocity ? Otherwise the alinement would've been broken before $t+\large\frac{x}{c}$ – pushkin_ Apr 25 '19 at 14:55
• Photons travel as waves (see diffraction), don't have a position until absorbed, and don't have an effect on each other. Your question seems to present photons as little balls, which is incorrect. – safesphere Apr 25 '19 at 15:23
