Q: Why is it that objects in orbit around other objects, tend to do that in elliptical patterns, and not circular patterns? I can picture objects of great mass, planets and stars warping the fabric of space time, and how moons and whatnot get caught spinning in the orbit. But can't wrap my head around the elliptical aspect of the deal.
Q: Why is it that our galaxy is (very loosely speaking) disc shaped? I can picture how the spiral arms are created from the spin, and I can picture how the black hole at the center (perhaps with the aid of dark matter) keeps everything together. But why is it pancake-like, rather than sphere-like, in shape?
Thanks!
