Blitzer Bonus || A Radical Idea: Time Is Relative The Persistence of Memory (1931), Salvador Dali:. © 2011 MOMA/ARS. What does travel in space have to do with radicals? Imagine that in the future we will be able to travel at velocities approaching the speed of light (approximately 186,000 miles per second). According to Einstein's theory of special relativity, time would pass more quickly on Earth than it would in the moving spaceship. The special-relativity equation R, = R 1 - gives the aging rate of an astronaut, R4, relative to the aging rate of a friend, Rf, on Earth. In this formula, v is the astronaut's speed and c is the speed of light. As the astronaut's speed approaches the speed of light, we can substitute c for v. R, = R Einstein's equation gives the aging rate of an astronaut, R., relative to the aging rate of a friend, Rf, on Earth. R. = RN/1 - (9) The velocity, v, is approaching the speed of light, c, so let v = c. R. = R1 The velocity, v, is approaching the speed of light, c, so let v = c. = R;V1 – 1 (9) - = 1? = 1:1 = 1 = R;Võ Simplify the radicand: 1 – 1 = 0. = R;•0 Vo = 0 = 0 Multiply: R,-0 = O. Close to the speed of light, the astronaut's aging rate, R, relative to a friend, Rf, on Earth is nearly 0. What does this mean? As we age here on Earth, the space traveler would barely get older. The space traveler would return to an unknown futuristic world in which friends and loved ones would be long gone.
