How come we don't just fly out, i mean were spinning close to the galactic edge, doesn't a galaxy lose entire solar systems over time?

It's just gravity. Just like the gravity that keeps the Earth from flying out of the Solar System.

No way, we are not the only solar system in the galaxy. There are at least 200 billion stars on our galaxy. And more than half of them are accompanied by planets. That mean more than 100 billion other solar systems. Astronomers are searching for life, its not that easy you know. Its not like you could just point a telescope and look for an alien, its much more complicated and costly. Half of our galaxy is block because of all the gas and stars in the way. Our galaxy is really big, its nearly impossible to search all of it.

Nah. It's for the same reason Earth doesn't just 'fly out' of the solar system - we're held in by it's gravity.

Its an indication that the Universe was created from the external in the form of an inward Spin .Rather than a Nuclear singularity at the Center of the Geometry of the Universe.

gravity holds everything together. and this is also something that some say is a result of dark matter, which gravitationally links things together.

Gravity is what holds it all together.

...I wonder if all of the galaxies are revolving around a super-massive object, and if they are, what are these super-massive objects revolving around, and so on...
