E = mc 2 Yeah So What?

Outstanding Science Issues in 1900

This is an Original Idea  Requires the speed of light to be finite  Light has an energy related mass and is effected by gravity  Mass can be converted to Energy  now we know how stars shine  Gravity = curvature of space-time; Mercury orbits in curved space due to proximity to the Sun  Light can’t escape the Universe Universe

This Idea Seems Ludicrous  In a letter to a friend, Einstein writes: "...The relativity principle in connection with the Maxwell equations demands that the mass is a direct measure for the energy contained in bodies; light transfers mass... This thought is amusing and infectious, but I cannot possibly know whether the good Lord does not laugh at it and has led me up the garden path."
