So, the earth is falling around the sun, the the sun/solar system is falling (around?) within the Milky Way, is the entire Milky Way falling? Is everything in space continuously falling at relative velocities to each other? If everything is falling does the expansion of space mean there’s always room for everything to continuously fall? Or if space is 4 dimensional and finite does everything just fall and curve in a way we can’t perceive?
I’ve got a lot fundamentally wrong in my thinking, I have no doubt.
