: : I disagree with the pixel effect, but I'm not going to get into that. I'm going to change the situation of the trains for a second. Lets asume I decide to write 1 then 1/2 and continue to write having it everytime, it would take me forever to get to 0. That's because I'm taking a few seconds between every fraction. There is an infinate amount of points between the two trains, but it's going through all of those points. Time doesn't slow down when the trains get really really close to each other, all of those points are gapped in a certain lenght of time. : : 1 second apart = 1 meters : : 1/2 second apart = 1/2 meters : : 1/4 second apart = 1/4 meters : : 1/8 second apart = 1/8 meters : : etc. : : 0 seconds apart = 0 meters : So, the "Minimum Distance" does not exist because the number of points between two trains is infinite at every distance between them? : It makes sense

Exactly, Just to complicate it more. This is asumeing the trains will "touch". Accually the electrons will not allow other electrons to touch them, the collision will not be strong enough to affect the atoms. But there is an infinite amount of points between every distance.
