Physics 62.1 Understanding Space, Time & Relativity (15 of 55) Why Distance & Time are Relative

Visit http://ilectureonline.com for more math and science lectures! In this video I will explain how an observer A (on Earth) and observer B (on a space ship v=0.99c) see and experience distance and length differently. As v increases towards c, distances to all objects in the universe shrink and everything appears closer to observer B. Next video in this series can be seen at: https://youtu.be/ilkw0lep3nE
