Space Behavior

Anyone who has taken a physics class knows that gravity is one of the four fundamental forces of our universe and the singular force that gives weight to every object. Gravity keeps planets, solar systems, and even galaxies together but, shockingly, it is the weakest force in the universe.

I was surprised when I first read this, because it goes against everything I've thought about in relation to gravitational fields, gravitational potential energy, and Newton's law of gravitation. Also, I have always heard how astronauts have to get used to the force of gravity when they come back from space missions, so I figured it must be something powerful. It seemed to be the reason for a lot of motion behavior on Earth, but as it turns out it is just a small part of it.

Something else I discovered about space today is that everything is constantly moving. Planets in our solar system are not the only ones that orbit matter. In fact, our solar system is constantly orbiting around the center of the Milky Way, it just takes much longer due to the amount of distance it has to cover. Even our galaxy is orbiting around the center of the combined mass of the galaxy. This means that we are never still and are moving much more and much faster than we realize at all times!
