Which twin is younger in the 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 the twin in a rocket ship looks younger than the other twin after 60 years does time on earth differ on the time in the outer space why?

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.

Who invented twin paradox?

History. 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 paradox and how does it work?

The confusion caused by the phenomenon of time dilation has long been encapsulated in the so-called “twin paradox” stated as follows*: One of a pair of twins (the “traveling twin”) travels to and returns from a very distant destination at a speed approaching that of light the other (the “Earth-bound twin”) stays home.

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 second paradox?

The second paradox is a bit more technical, and really comes to the heart of what physicists mean when they talk about relativity. The entire scenario is based on the idea that Biff was traveling very fast, so time slowed down for him.

What is the effect of acceleration on a traveling twin?

The acceleration causes the traveling twin to change from one constant velocity reference frame to another and produces effects that can be measured locally by the traveling twin in the form of inertial forces that can knock things over, compress springs, and generally endow objects with weight.
