  1. Shouldn't it be T_m/T_s in the Teen level? Since 2L is the distance covered by the photon to measure a unit of time in the stationary clock, wouldn't T_s = 2L/c? Similarly, T_m = 2D/c. I think this also makes more sense, since as time increases for the clock in motion, it's perceived to be slower. More time = slower. I don't know though, the idea is still more or less the same, just wanted to check

  2. unfortunately, It seems surprising that the real problem of traveling back in time is not considered here

  3. The RIDICULOUS IDEA/CONCEPT Of time dialation cannot be proved because you cannot travel at or near the speed of light.
