Einstein spent the second part of his life trying to develop a "complete theory" that
would explain all the forces and phenomena in the entire universe. He never finished it.
Many believe that Einstein spent the last part of his life "spinning his wheels" working on
this theory. Today, scientists see value in Einstein's idea and are still trying to come up
with a "theory of everything."
