o The universe is so vast in relation to the matter it contains that it can be compared in the following way: A building 20 miles long, 20 miles wide and 20 miles high that contains 1 grain of sando The three most common elements in the universe are 1) hydrogen; 2) helium; 3) oxygen.
Scientists believe that hydrogen comprises approximately 90 to 99 percent of all matter in the Universe.
o A bucket filled with earth would Weigh about five times more than the same bucket filled with the substance of the sun. However, the force of Gravity is so much greater on the sun that a man Weighing 150 pounds on our planet would Weigh 2 tons on the sun.
