One of the earliest and most wellknown thought experiments to feature time dilation is the famous twin paradox, which demonstrates the curious effects of time dilation at its most extreme. Because you have mass increasing as the speed increases, so you need bigger force to get acceleration and it is possible that the time dilation happens exactly in moment when this force is producing time dilation and contraction. Nov 05, 2015 the classical doppler shift would be a bigger problem assuming one is orbiting the black hole to avoid falling in. Time dilation definition of time dilation by merriamwebster. But at high speeds, when v 2 c 2 become closer to 1, but never able to reach it, 1v 2 c 2 12 becomes smaller and smaller, which makes time dilation t 1 growbecome greater and greater, which causes the time of the observer to appear faster and faster, thus making time appear to be slower to the person traveling at those speeds. A major consequence of this apparent paradox is that time flows at different rates in the two frames.
