Does time dilation also work for regular quartz clocks if you/it is moving at the speed of light(c). If so, if you move at the speed of light will others see you aging slower. Finally, if there are 2 twins and one is on Earth while the other is sent travelling at the speed of light in space, when they both are brought back to Earth after many years, is one of them younger?
