why do Planets have elliptical orbits ,why do they just not have circular orbits ,I understand that the sun is like a bowling ball on a sheet of rubber and the planets in our solar system orbit the bowling ball as if i got a marble and rolled it onto the sheet of rubber but after a while the marble would have a circular orbit ,are we still at the stage where the marble was just thrown onto the rubber sheet ,and will we eventually all clump together towards the sun and burn up or will the sun eventually loose its gravity and we will be thrown into outer space
also why is the universe accelerating should it not be slowing down as the energy from the big bang looses strength
