What breaks the symmetry in twin paradox?
The origin of the true paradox is that we identify two types of symmetry: the symmetry between the two individual trips within a journey and which is broken by the definition of that journey, and the symmetry that corresponds to the notion that motion should be relative.
Is twin paradox resolved?
The so-called “twin paradox” is easily resolved by noting that there is a physically meaningful disinction between the experiences of the two twins during the trip. As a result of the fact that their experiences are different, there is no a priori reason for them to come to the same conclusion.
Is the twin paradox symmetrical?
The twin paradox uses the symmetry of time dilation to produce a situation that seems paradoxical. The really strange thing about time dilation is that it is symmetrical: if you and I have relative motion, then I see your clock to be running slow (with respect to my frame), and you see mine to be running slow.
Who invented twin paradox?
In his famous paper on special relativity in 1905, Albert Einstein deduced that when two clocks were brought together and synchronized, and then one was moved away and brought back, the clock which had undergone the traveling would be found to be lagging behind the clock which had stayed put.
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.
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.
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.
What is the paradox of the traveling 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. (Many of us solved this problem in sophomore physics, to demonstrate one effect of the absolute nature of the speed of light.)
