What is really happening is that everything (atoms etc..) are made of fields in which disturbances&amp;#x2F;patterns travel at the speed of light.  When an object is moving through space, the fields have to move extra far to cover the distance through space, as well as to do the usual oscillations&amp;#x2F;vibrations&amp;#x2F;movements that give timing effects.  This is where time dilation comes from.  It&amp;#x27;s best understood with the reflecting-mirror-as-clock thought experiment.</text></comment>
