: If this question can be answewred then maybe I can get on with my life. Actually I don't even know how to phrase the question exactally but here goes. Lets say two trains were on a path to a head on collision. What would be the minimun distance between the two trains before they collieded or came in contact with each other? Obviously there must be a point at which if either of the two trains moved any further torwards each other they would collide and come in contact with each other. BUT! at that point where if they moved any closer they would collide, there must be some empty space between the two trains because they have not collided yet. Therfore if there IS empty space between the two trains, no matter how small, you can move in closer at least half of that remaining distance... making that minimum distance moot. right? RIGHT? Okay lets look at this in mathmatically. Lets say for example you had some type of device that could electronically measure the distance between the two trains. I am going to : use the number zero (0) as the point of contact. As each train moved close torwards each other, your measuring device would count down.. 9 - 8- 7 - 6 - 5 - 4 - 3 - 2 - 1 Now using the number one (1) at the minimum distance before contact, and zero (0) as contact, how could this minimun distance exist because 0.5 would be even closer that the original minimum distance of one (1). and 0.4, 0.3, 0.2, 0.1, 0.01 so forth and so on...how could you possible reace zero (0)???????!!!!! Someone please answer this so I can stop wasting so much time pondering on this. Thanks, Randy

OK. This is my thought (somebody please correct me if I am wrong). If we zoom a spacetime we would see that it's not smooth but "filled" with very small cracks that distort it (a wormholes you may say). So that would mean that the spacetime is in some way quantized (like digital picture with pixels as smallest elements). This roughness of spacetime could explain that "Minimum Distance" you mentioned. I don't have any better explanation, so could someone provide something better :o)
