Einstein's Life:
The general theory of relativity.
¥In 1915 Einstein completed his general theory of relativity which changed our views of space forever.  The theory predicted that space is curved as a result of the gravitational force, and this curvature effects anything that moves though this space (event objects with no mass).
¥Einstein's predictions were confirmed in 1919 with observations made during a solar eclipse.
¥Einstein wrote to his mother:
¥"Dear Mother, -- Good news today.  H.A. Lorentz has wired me that the British expeditions have actually proved the light deflection near the sun. "
