They have the same gravitational effect This was one of the major vindications of Einstein's theory. It turns out that the planet Mercury does not orbit as it "should" according to classical physics; astronomers thought that there must be an additional planet located inside the orbit of Mercury that was affecting its orbit. However, no search for this planet (tentatively called "Vulcan") ever turned up anything other than a few asteroids, far too light to have the observed effect However, because energy has effective mass (and therefore gravitational pull), Einstein's equations predict an orbit for Mercury that exactly matches the observed orbit.No additional planet is needed.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
