The case of the travelling twins « Einstein-Online
WebJun 26, 2024 · Early in your life, you discovered that your twin was the evil one. To spare the world her monstrosities, you sent your twin off in a rocketship at 90% of the speed of light, putting her safely out of reach of the Earth. Unfortunately, due to time dilation, time for your twin passes at of the rate it passes for you. WebWe can see from the graph that at “low” speeds there is only a small change in time dilation (i.e. the flow of time doesn't change very much), but at speeds over about 75% of the speed of light the effect of time dilation is quite dramatic. Even at the "low speed" of 10% of the speed of light (300,000 km per second, or 186,300 miles per second) our clocks would … WebOur twin problem is the same thing, at the same speed, but over a longer time—we conclude that observation of any earth clock from the spacecraft receding at 0.6 c will reveal the clock to be running at half speed, so the brother’s flashes will be seen at the spacecraft to arrive every two months, by spacecraft time. rayleigh to southend on sea
