“Some people say light is waves, and some say it’s particles, so I bet light is some in-between thing that’s both wave and particle depending on how you look at it. Am I right?” “YES, BUT YOU SHOULDN’T BE!”

And that point is inside the sun.
No actually. Due to Jupiter, the centre of mass of the solar system is actually very slightly outside of the sun
Leave it to Jupiter to mess yet another thing up
Stupid lazy ass diabetus planet doesn’t even have enough mass to fuse its hydrogen.
Wouldn’t the center of mass constantly be shifting by the planets’ varying positions in orbit?
Yes, but it’s mostly shifting because of Jupiter. It’s just so dang heavy. Like, a couple times heavier than every other planet put together. I don’t have the brain wattage to do the cool math right now, but a quick google search says that while the barycenter of the solar system does depend on all the planets, more often than not, it is outside the sun
Cool. I learned something today
Wait I’m sorry, are we saying that the earth’s orbit isn’t almost entirely dictated by the gravitational pull of the massive star at the center of our solar system? I am a simple man, I apologize if that is a stupid question.
When dealing with gravitational systems the gravity of each object has to be taken into account. So even though the sun is 99.999% (hyperbole) of the gravity in the equation, the earth’s gravity contributes that small 0.001% and thus the “center” of where they orbit isn’t truly the center of the sun. Tack on Jupiter, which is much more than a fraction of a percent and that “center” moves even farther away from the middle of the sun.
To look at it further, if you had two objects of perfectly equal mass and no other gravitational interference, they would orbit around a point in the middle of each other since their pull is equal. So it’s basically a sliding scale of sorts.
Hope that explains it!
No the comic is pointing out that the sun and the earth are both orbiting the milky way galactic center.
Edit: While also true, I was wrong, they orbit the center of mass of the two body problem (earth and sun). I still think that’s too simple of a way to look at it. It’s not a two body problem and the other planets and the whole galaxy are also in play.
I mean technically every body in the entire universe exerts gravity on everything else as long as it’s in your light cone
What’s a light cone?
A not too heavy cone.
