Einstein's twin paradox explained - Amber Stuver

Follow two astronauts into outer space to explore time dilation and Einsteins theory of relativity through the Twin Paradox thought experiment.

--

On their 20th birthday, identical twin astronauts volunteer for an experiment. Terra will remain on Earth, while Stella will board a spaceship. Stellas ship will travel to visit a star that is 10 light-years away, then return to Earth. As they prepare to part ways, the twins wonder what will happen when theyre reunited. Who will be older? Amber Stuver investigates the Twin Paradox.
