: : PLEASE! posted by Tomislav Strelar on September 08, 1998 at 01:59:42:: : : : If this question can be answered then maybe I can get on with my life. Actually I: : don't even know how to phrase the question exactly but here goes. Lets say two: : trains were on a path to a head on collision. What would be the minimum distance: : between the two trains before they collided or came in contact with each other?: : Obviously there must be a point at which if either of the two trains moved any further: : towards 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. Therefore 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 mathematically. 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: : towards 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 minimum 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 reach zero (0)???????!!!!! Someone: : please answer this so I can stop wasting so much time pondering on this. Thanks,: : Randy : : PLEASE! posted by Tomislav Strelar on September 08, 1998 at 01:59:42:: : : 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): : Posted by Michael Moosman on September 09, 1998 at 19:46:55
