... 1 light year = the distance light travels in one year = almost 10 trillion kilometers or 6 trillion miles (one trillion = 1012 = 1,000,000,000,000) Because light takes time to travel through space, when we look farther away in distance, we look farther back in TIME. The farthest we can see in space ...

... The constant of proportionality (G) in the above equation is known as the universal gravitation constant. Henry Cavendish determined the precise value of G experimentally in the century after Newton's death. The value of G is found to be G = 6.673 x 10-11 N m2/kg2 The units on G may seem rather odd ...
