The Twin Paradox illustrates the effects of time dilation in special relativity, where one twin travels at near-light speed while the other remains on Earth. The stationary observer on Earth sees the spaceship's clock running slow, while the astronaut in the spaceship perceives the Earth clock as slow as well. The resolution of the paradox occurs when the astronaut turns around to return to Earth, which breaks the symmetry of their experiences and results in the traveling twin being younger upon reunion. This phenomenon is a direct consequence of the principles of special relativity.
