If you had one (or more) fact(s) about space that you wish everyone knew what would it be?
This is going to sound silly, but I mean this:
Space is huge.
I know that feels like a "duh" moment. But I cannot express how beyond human understanding the vastness of space is.
You can fit all the planets between Earth and the Moon.
A lightyear is approximately 5.88 trillion miles.
The closest star to us (besides the sun) is Alpha Centauri which is 4.4 lightyears away. That's 25.5 trillion miles.
Our galaxy is approximately 100,000 lightyears across. That's a lot of miles.
The Milky Way spins, too. The last time our galaxy was in this position was 225 million years ago.
Deep field photos like this:
Those aren't stars. Those are all galaxies. Galaxies. Full of billions of stars and planets.
And that's only a small percentage of the universe.
Our nearest galaxy, Andromeda, is 2.5 million light years away.
The observable universe is 93 billion lightyears across.
Yeah. Space is fucking BIG.
