Rating: 4.0; Vote: 1
The Milky Way is our neighborhood in the universe. It-s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular. Galaxies can collide, and grow in size by eating each other. Crash Course Astronomy Poster

What about oppoosites attract and equals repel. Things orbit other larger bodies because they develop an equality of potential mass. While this equality is only a temporary condition as in the perihelion moment, the orbiting body becomes equal in potential mass with the primary body and they repel each other. It works on a sateliite basis such as arth and our Moon and on a Planetary basis such as with Earth and our Sun, and it apply to galactic masses as well.

Science keeps telling us about space -dust-. To date I have never heard of what this dust is composed of. Ordinary Earth dust is primarily a compound of some form of Oxygen or Carbon in a compound form. In the free space surrounding galaxies, dust would attract protons gravitationally but individually and collectively

1: 41 You've got it a bit mixed up. Both of the arguments you present - by Shapley and Curtis - are arguments that the Milly Way is the entire universe. It was actually Shapley who argued that other galaxies must be impossibly far away - not Curtis. Great video, though.

Galaxies are their imaginary God's
No objects exist in the sky structured in galaxy form. All stars move from East to West, no star orbits aother one, no aother obnect is rotaging
Do you teach the fiction dtructures galaxies, in schools, as if they were real?

What are those bright circular like shapes at the center of the galaxy?
.
I-m not so sure, but from what I remembered from what I-ve read somewhere, the center of the milky way is a blackhole )

I'd say the suburbs are THE place to be. We wouldn't enjoy being too close to the intense actions of some of the more extreme events in the Hell's Kitchen of the galaxy.

Where are the debris of exploded and collided galaxies? - in the pacific oceans?
No. No - galaxies- are colliding -----------
