Secondly, suppose there is some super advanced civilization (your use of “” doesn’t seem to make any sense), the reason they probably haven’t completely colonized the entire Milky Way Galaxy is that for them, as for us, the laws of physics make it pretty much impossible to achieve interstellar travel because of the . And even if they could colonize some surrounding systems by now, it would take light and radio waves to reach us from the other side of the galaxy.
We live in a very cool galaxy called the Milky Way. Just seeing it with visible light waves is cool enough!
We can also see it using different light waves, such as gamma rays, x-rays, near-infrared, far-infrared radio waves and microwave. Each view is different and shows you a very dynamic and energic galaxy, right out your back door!
Here’s what it looks like in visible light:
You can go outside and see this with the naked eye. What you’re looking at is our own galaxy seen edge on (because we are in an outer edge ourselves).
Now, here is the Milky Way as seen from various other frequencies of light. As you can see, we live in a beautiful galaxy! Full of light, energy, radio waves, gamma rays, x-rays, infrared light and so on:
Somewhere in the middle there is a big black hole. We’ve been able to detect the existence of our black hole because we can see stars orbiting around it very quickly, even though black holes themselves emit no light at all.
