Perspective: Parallax

The video explains the concept of parallax, starting with a simple pencil experiment to demonstrate how our eyes perceive distance. It then extends this concept to astronomy, showing how parallax is used to measure the distances of stars from Earth. By observing stars from different points in Earth's orbit, astronomers can calculate these vast distances using trigonometry.
