  28. 28. Inscientific notation a positive exponent means the object is______ and a negative exponent means an object is _______. Big/far away 500 Small/very Mystery Ball close
  29. 29. According to the Big Bang theory this is howthe universe began. The theory asserts that our entire universe was created when a tiny (billions of times smaller than a proton), super-dense, Final super-hot mass "exploded" and began expanding veryQuestion rapidly, eventually cooling Mystery Ball and forming into the stars and galaxies with which we are familiar.
