It's time to explore space, Einstein's theory of relativity and the world of the stars!
Symphony of Science looks at E=MC squared and Einstein's theory of relativity. Featuring Michio Kaku, Brian Cox, Neil deGrasse Tyson, Brian Greene and Lisa Randall.

Well we have one for you. The concept: relativity. That strange fantastic relationship between time, distance, and mass. Before we're finished, I think you'll agree that truth is stranger than the strangest fiction. Why do the stars shine? Why does the galaxy light up? E equals MC squared That is the engine that lights up the stars Energy turns into mass E equals MC squared - That is the secret of the stars Now listen carefully: The faster you move The heavier you get The energy of motion turns into M, your mass Energy of motion Energy equals Mass times the speed of light squared An awful lot of energy For a tiny amount of mass Light travels at the same speed No matter how you look at it No matter how I move, relative to you, Light travels at the same speed No matter who is doing the measurement And no matter what direction you are moving The speed of light is the same No matter what direction, or how fast As you travel faster Time slows down Everything slows down Time slows down when you move Time passes at a different rate Clocks run slow It's a monumental shift in how we see the world The beauty, the majesty, The power of the universe Into a single equation (refrain) It's a beautiful piece of science It's a beautifuly elegant theory It's a beautiful piece of science A planet like the Earth is kept in orbit Because it follows curves In the spatial fabric caused By the sun's presence Space and time are bent by stars and planets As things move through this curved space, they bend Now all of this is illustration of the fact that time and space are linked together. As you're moving through bent and curved space and time, You feel like you feel a force (x2) That force is gravity (refrain) That is the secret of the stars
