Question : The twin paradox is associated with:
Option 1: The theory of relativity
Option 2: Particle physics
Option 3: Hydrodynamics
Option 4: Quantum mechanics
Correct Answer: The theory of relativity
Solution : The correct answer is the theory of relativity.
A thought experiment known as the twin paradox helps explain special relativity's theory of time dilation. In the twin paradox, one twin remains on Earth while the other goes close to the speed of light on a rocket ship. Time dilation causes the twin on the rocket to age more slowly than the twin on Earth.
