newton figured out that in order for kepler's laws to be valid, an orbit should be an eclipse with sun at one focus.
my question is regarding einstein's view of gravity as a warp in space-time by the star. When I try to visualize the sun sitting on a piece of space-time fabric, I can only picture the sun being in center and then the planets would orbit in circular path. I have trouble picturing the sun causing this warp by sitting at a focus and causing elliptical orbits.
Can someone explain?
