Astronomy thread

I totally get that, kindness…
What I don’t get is how it makes sense to say Jupiter’s orbit is anymore outside of the sun than the other planets’ orbits, when all the planets and the sun actually orbit the barycenter of the solar system. This would mean that all of the planets are orbiting a point that is outside of the sun. Do you get what I’m saying?

I actually fell asleep last night thinking about this. I understand that the center of gravity between Jupiter and the sun lies outside of the sun. I don’t understand how it makes sense to say that Jupiter therefore doesn’t orbit the sun. None of the planets really do, we just say that they do. They all pull on each other and the sun. The entire solar system orbits the barycenter of the solar system. The sun, all the planets, and the moons and asteroids revolve around that point. It should be the same for each of the planets, unless there’s some special way of defining orbits where you end up with multiple orbits for each planet (which wouldn’t actually be that strange).

I saw the total solar eclipse last summer. It was the most astounding experience of my life. Eerie and frightening and beautiful.

That’s true, but the answer depends on whether you’re defining the barycenter between just two masses (e.g., the sun and Jupiter) or the barycenter of the solar system.

@anon9798425 I think you should stay awake tonight and ponder this important concept and also bake cupcakes representing the sun and planets and build a cupcake planetary model. If you eat any of the cupcakes you will throw off the barycenter!

EDIT: Look! Planet cupcakes!

We watched a black hole expell matter of some kind recently for tge first time… And were still not 100% they exist? Is that right.

You mean to say a black hole vomited? :face_vomiting: :scream:

Hey i just thought of a black hole theory ive never heard… what if an advanced race has used all of their universe’s matter… and tapped into ours using black holes… they absorb all matter including light mush it into its simple form all hot and ready for rework and placement in their own universe… boom heads exploded…

I like thinking about aliens. More about how they probably exists but we have no solid proof. I heard a great explanation for a reason why we havent been contacted by alien life forms.

Lets say we have an ant hill in the middle of the forest. And right next to the ant hill, they’re building a ten-lane super-highway.

And the question is “Would the ants be able to understand what a ten-lane super-highway is? Would the ants be able to understand the technology and the intentions of the beings building the highway next to them?

To the aliens we might be the ants, so there is no real reason why they would stop what they were doing to explain it to us, since we would never be able to comprehend any of it.

There’s a lot of different theories. I especially like the Fermi paradox. If anyone wants to learn about some of them I found a good post that explains it very good and also in an easy to understand way.

Splendid! I’ve always wanted to devour the universe. My next project will be to understand how all the stars of the Milky Way pull on our planets and what they’re all actually orbiting. Naturally, I will require a cupcake model of the galaxy to do so. I trust you will bake one for me by tomorrow?

I swept a pile of moldy looking leaves off the top of my mom’s roof with an ancient corn broom.
Something rolled away from the pile and I saw two eyeballs looking up at me.
It was a stinking decayed squirrel!
In the corn broom was stinky smelly squirrel pieces. I thought I was going to be sick.
Just thought I’d share…

I have an 8 inch Dobsonian reflector and I spent over an hour two nights ago just staring at the Horsehead nebulae. Too cool.

On a side note I’m having fun with the game Kerbal Space Program on PS4

When I was a teenager I was heavily into astronomy. I wanted to become a professional astronomer. Had a 4" newtonian reflector telescope and got to know the sky well. Then when I was 18 or so my interest died out a little and unfortunately I had to sell my telescope as my dad needed money.

To this day i still like astronomy but I never managed to regain that obsession I had with it.
