Universe make lets you the many possible histories and futures that a universe can have. Scientists believe that our universe is expanding at an accelerating rate and will expand forever. If the composition of our universe were to change, however, its future could be quite different. Our universe contains three things: radiation, matter, and dark energy. Together, these three components control the evolution of the universe. Universe Maker invites you to tinker with the composition of our universe and watch its history and destiny change.
