For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.
Planets and stars and galaxies are there. You can see them because they’re right over there. Like, the moon is a big fucking rock flying around the earth. Jupiter is even bigger. I see it through a telescope and think “wow that’s pretty,” but every once in a while I let it hit me that I’m looking at an unimaginably large ball of gas, and it’s, like, over there. Same as the building across the street, just a bit farther.
The stars, too. Bit farther than Jupiter, even, but they’re right there. I can point at one and say “look at that pretty star” and right now, a long distance away, it’s just a giant ball of plasma and our sun is just another point of light in its sky. And then I think about if there’s life around those stars, and if our star captivates Albireoans the same way their star captivates me.
And then I think about those distant galaxies, the ones we send multi-billion dollar telescopes up to space to take pictures of. It’s over there too, just a bit farther than any of the balls of plasma visible to our eyes. Do the people living in those galaxies point their telescopes at us and marvel at how distant we are? Do they point their telescopes in the opposite direction and see galaxies another universe away from us? Are there infinite distant galaxies?
Anyway I should get back to work so I can make rent this month
If I point my finger at one of those galaxies, there’s more gas and shit between us within a hundred miles of me than there is in the rest of the space between us combined
What’s even more fascinating is that most of the stars we see in the sky are afterimages of primitive stars that died out long ago yet they shine as bright as the stars alive today
That doesn’t seem right. The galaxy is only 100,000 light years across (give or take) and the life span of stars is measured in billions of years.
Most of the stars we see are in our galaxy, so at most, we are seeing them as they were 100,000 years ago, which means that the vast majority of them will still be around, and looking much the same as they did 100,000 years ago.
I seem to have made a mistake then. Thank you for correcting it.
Thinking about it further, if we’re talking about stars that we can see with telescopes, Hubble, James Webb etc, then you’re on the money. Stars in remote galaxies far outnumber the ones in our galaxy and show us glimpses of the early stages of the universe. And many of those stars are long gone
Not too sure where you got that number from. From what I can find, the radius of the observable universe is estimated to be about 46.5 billion light-years.
Edit: I see now that you are talking Galaxy. That’s different.
The original comment was about stars we can see in the sky, so I was assuming naked eye

I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.
You should try Space Engine. It’s a program to explore the universe, based on real telescope data. It also has the ability to procedurally generate galaxies, planets, and stars in unobserved parts of the universe.
I can really relate to this. I remember a weird night in my teens where I must’ve spent at least an hour staring out of my bedroom window at the moon, because really for the first time I’d had the exact same thought. It’s right there. It’s so easy to get desensitised to that and to just think of it all as an image projected on the sky. The thought has never really left me and even now I still linger on the moon every time I see it and try to acknowledge that it is a 3 dimensional object lol.
The fact that the moon is tidally locked probably doesn’t help, if it rotated it would be easier to see it as a sphere instead of an image
In the same vein, I like to remind myself that every field in physics is literally happening all around me, right now, and it always has been, in fact, I’ve never seen anything without these invisible fields in it and for some reason, that really makes me super aware of our place in the order of magnitudes.
It’s wild we can see so much further down than up.
First time I saw Jupiter through a telescope I got hit hard by the feeling: “Oh shit, that giant monster is real”.
Samesies. You aren’t alone. We have a support group.
“Just a bit farther” is quite the understatement!

A moon isn’t that strange, our moon is.
First, it is massive compared to Earth. The mass of the Moon is so large that it messed with definitions of planets and plutinos.
Second, the Moon’s size and distance from Earth is a near match for the Sun’s, which is really rare.
And for a strange fact, the Moon is about as reflective as worn asphalt. The Moon looks white in photos of just itself, but it is a dark grey when in photos with Earth.
