Do you age slower if you travel at the speed of light?
We do not age slower if we go at the speed of light but the time stops when we go at the speed of light. The reality is a object having a definite mass cannot achieve speed of light because mass is dependent on speed and when the object reaches near the speed of light we need infinite force to keep it accelerating.
What is the importance of twin paradox in explaining the special relativity?
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.
What are the different explanations of the travelling twin paradox?
Starting with Paul Langevin in 1911, there have been various explanations of this paradox. These explanations “can be grouped into those that focus on the effect of different standards of simultaneity in different frames, and those that designate the acceleration [experienced by the travelling twin] as the main reason”.
Does the travelling twin have two inertial frames of reference?
However, this scenario can be resolved within the standard framework of special relativity: the travelling twin’s trajectory involves two different inertial frames, one for the outbound journey and one for the inbound journey.
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.
Is there symmetry between the spacetime paths of the twins?
However, this scenario can be resolved within the standard framework of special relativity: the travelling twin’s trajectory involves two different inertial frames, one for the outbound journey and one for the inbound journey, and so there is no symmetry between the spacetime paths of the twins.
