Is it a scientific fact that all stars, planets and galaxies swarm (swim,metaphorically speaking) into space?

Answer 1

If you're talking about the movement of stars and planets, then yes, they do all move, because they all move relative to each other. And yes, they do move as a "swarm" because gravity will keep the closer bodies together and bring them into orbit around each other...

Of course, you can't discount any rogue planets/asteroids that have been ejected from their orbit and are now flying aimlessly in space...

But of the "swimming".... I'm not sure... perhaps they're swimming in space-time?

Answer 2

Galaxies are sort of like swarms, because there is no single object that dominates the gravitational force: everything in the galaxy is attracted to everything else, and so each star follows an orbit that is determined by all the other stars. This is unlike the solar system, where the mass of the Sun dominates all the planets, and all the planets rotate around the Sun with only small perturbations from the other planets.

Answer 3

Well, they move, usually in an orbit. It's hard to answer a question about scientific fact that uses metaphor. It's kind of contradictory

Answer 4

that something metaphorically does ANYTHING is not a scientific fact. You seem to be intentionally confusing yourself.

Answer 5

Please clarify what you mean ! I have never heard an astronomer talking about Jupiter doing the backstroke.
