The Twin Paradox – Corrective Overview

The “twin paradox” in special relativity is often described as a contradiction: one twin travels at near-light speed while the other stays on Earth, and upon reunion, each expects the other to have aged less. The resolution is straightforward: the traveling twin’s worldline includes acceleration and turnaround, breaking the symmetry. Proper time integrals show the Earth twin experiences more elapsed time. No paradox remains.
