The twin paradox, also known as the clock paradox, is a thought experiment in the theory of relativity.

Explanation of the Paradox

Imagine two twins, one who stays on Earth and one who travels through space at a high speed.

According to the theory of relativity, time passes more slowly for objects in motion relative to those at rest.

Temporal Dilation

As the traveling twin moves away from Earth and back, their journey causes time to pass slower for them compared to the twin who stayed on Earth.

This results in the traveling twin aging slower than the twin who remained on Earth, leading to a paradoxical situation.

Resolution of the Paradox

When the traveling twin returns to Earth, they will indeed be younger than their Earthbound counterpart.

This seemingly paradoxical scenario is explained by the fact that the traveling twin underwent acceleration and changed inertial frames during the journey.

Acceleration and Frame Changes

Accelerating and changing frames of reference breaks the symmetry of the situation, allowing for one twin to age less than the other.

While the twin paradox can be puzzling at first glance, a deeper understanding of the principles of relativity clarifies the situation.
