 Description: This is a program developed to approximate the length of time that it would
              take for the user to travel to another planet FROM the planet Earth. It also
              Gives the user an approximate weight in pounds relative to the weight of the
              user on planet earth to the gravitational pull of the destination planet
              of which they plan to travel.
              There are also advertisements from GUAGECAGE TECH Inc. here and there in the program
              depending on what the user may need to assist them while visiting their
              destination planet.
