But they don't. We know they don't. Not unless you use a weird definition of orbit that is very different from the one lotsofpulp was using. And if you do that you're not countering their argument, you're misconstruing it.
- TeMPOraL 9mo agoWe know they do. An orbit is a mathematical object, and elliptical orbits only exist in universes that have exactly two objects with mass in them. Add another object, even far away, and as far as we know[0] we no longer even have a closed-form description of resulting motion patterns. And our universe has tons of matter with gravitational mass everywhere, few other types of interaction beyond gravity, and a vacuum that just doesn't want to stay empty. -- [0] - Not sure if this was mathematically proven, or merely remains not disproven.
- Dylan16807 9mo agoWhen I said "don't" I was talking about the complex shape that applies to orbiting the Earth, old school epicycles. Actual orbits being slightly off ellipses isn't what I meant.

And if you do that you're not countering their argument, you're misconstruing it. All of science is like this. Change your frame of reference/theory. Why did we pick one system vs another? Its arbitrary.
