When the speed of a relativistic particle is doubled, its linear momentum increases by a factor of: a. less than 2
b. 2
c. more than 2

powerful computers now, not then

force tends to be low and long diustance masses are high

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
