Space is mind blowingly large and is forever expanding. One is literally incapable of conceptualizing how big the universe really is.
13.2 billlion years ago
There are an estimated 100 billion galaxies within the observable universe. (what we know exists) Outside, however, there could be hundreds of thousands, maybe even millions or billions, of other galaxies, perhaps even seperate universes!
We are here! (somewhere)
All these other lights are the thousands upon thousands of galaxies that we have discovered.
To put the size into perspective:
Our Milky Way
Andromeda (closest galaxy to ours)
2.2 MILLION lightyears
Andromeda is currently traveling at 670,000 mph. Astronomers say that this galaxy will collide with ours 5 billion years from now.
One lightyear is equal to 5.87849981 x 10^12 miles. That is equal to 5,878,499,810,000 miles. Which is a lot.
Picture this: A lightyear is almost 6 trillion miles. The NEAREST galaxy to us is 2.2 billion lightyears!
Our observable universe.
in 1 universe.
