Why the twin in a rocket ship looks younger than the other twin?
After all, the twin on Earth can invoke time dilation: Moving clocks go slower, and so do the clocks of the moving twin. On these slower-moving clocks – and, by extension, in the whole spaceship – less time passes than on Earth, in other words: when the travelling twin returns, he is younger.
Why the twin rocket ship looks younger the other twin after 60 years?
So, during the trip back, both twins see their sibling’s clock going 3 times faster than their own. Factoring out the fact that the light-time-delay is decreasing by 0.8 seconds every second, each twin calculates that the other twin is aging at 60\% his own aging speed.
What is the twin twin paradox?
In this supposed paradox, one of two twins travels at near the speed of light to a distant star and returns to the earth. Relativity dictates that when he comes back, he is younger than his identical twin brother.
Is the accelerated twin older or younger?
“In the best known version of the twin paradox, the twin who is accelerated is younger,” Abramowicz and Bajtlik told PhysOrg.com. “In the version discussed by us the accelerated twin is older.
How does the twin paradox relate to the Doppler shift?
During the trip, both the traveler and Earth keep sending signals to each other at a constant rate, which places Langevin’s story among the Doppler shift versions of the twin paradox. The relativistic effects upon the signal rates are used to account for the different aging rates.
Why is the traveling brother younger than his identical twin brother?
Relativity dictates that when he comes back, he is younger than his identical twin brother. The paradox lies in the question “Why is the traveling brother younger?” Special relativity tells us that an observed clock, traveling at a high speed past an observer, appears to run more slowly.
