“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

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

As a middle ground kind of guy, I would like to pre-emptively state that a lot of us don’t actually think the answer is always the middle ground between two stances. It’s just that we’re more likely to propose a middle ground solution because we evaluate the plausibility of both stances in a more balanced way (as opposed to existing-stance-holders who are prone to bias towards their own stance.) When the two seem roughly equal in plausibility (which happens fairly often, otherwise the argument would be more one-sided,) that’s an indication to evaluate the middle ground as well.

Middle ground folks are often caricaturized as wanting to find the middle ground between an objectively sensible point A and a radically wrong point B, when the spectrum of opinions is sort of like [ - - - - - A - | - - - - - - B ]. In that caricature, we’re looking for a middle ground at point C [ - - - - - A - | - - C - - - B ], when in actuality we’re evaluating (and not automatically accepting) something two or three steps closer to A. In some such cases, A might already be the most sensible middle ground.

Middle of the ground people are mostly cowards too scared of conflict, or devoid of insight.

Maybe there’s a middle ground between our two views.

Sometimes, both can be wrong. Both orbit the moon

The Earth–Moon–Sun three body problem is apparently something that has been studied quite a bit in physics.

And of cause there are 3 camps and alot of disagreements but essentially, the majority of scientists argue, like me, that it is the moon which is the center. You can always cite some fringe scientists arguing otherwise, that doesn’t change the general consensus.

you are the barycenter of your own opinion

Is this… an introductory course in relativity, disguised as a joke?

Am I accidentally learning something here?

Guys?

It’s called a barycenter, kids, a common center that both objects circle around. That common center happens to be inside the sun, but that’s a topic for next week’s class in this semester’s AP Astrophysics program.

Same for earth and moon. The center is inside earth. But not that close to the center of the earth itself
