Are Orbits like this even POSSIBLE?!

We like to imagine of gravitational orbits as the conic sections: circles, ellipses, etc. That's only for two-body problems though. Let's take a look at three-body problems (and beyond) using Newtonian mechanics as well as General Relativity. How weird can orbits actually get?

*Minor Correction 1:* The elliptical tunnel at 1:37 is a little sloppy. If the squirrel is of typical squirrel-mass, then the bottom of the ellipse should dip farther down so that the center of the Earth is at a focus of the ellipse. If the squirrel is _abnormally massive,_ then the ellipse's location is fine (but the Earth should also be orbiting the focus on its own smaller ellipse). *Minor Correction 2:* I've been told that the prefix "peri-" means "around" or "about" as opposed to "close." I think all 3 of those English words mean the same thing given the context, but I acknowledge and respect your pedanticism 😉

@@georgemayanja7805 Compact objects in close orbit bleed off velocity by making gravitational waves. So besides the normal interactions you get orbits declining. It will result in collisions.

[@tommywhite3545]

But you got it right about "peri". Peri- as a prefix means "around" or "near" depending on the word. Perihelion means near the Sun. (Perimeter for example; around a meter.) So .. wth! We don't live in ancient Greece now do we? (Where peri NOT as a prefix meant "around" or "about".)

Years ago I wrote a program that simulates what you call free fall orbits using Newtons equations. It randomly generates a cluster of stars of various masses and gives them their initial velocities. When you click the Start button you can watch the cluster evolve. Some of the stars will eventually get kicked out of the cluster in pairs and become their own binary system.

[@edmundwoolliams1240]

Hey! I have a masters degree in mathematical and theoretical physics and have just started my career as a physics teacher, and I have to say that what is great about this channel is just how brief and straight to-the-point these explanations are, and yet they are precisely correct. I’ve seen too many YT videos that try to explain the things that you explain, but they don’t include the important deep, fundamental details that you manage to integrate into your videos, which I find awesome. You’re clearly extremely knowledgeable, as being able to explain these concepts as simply as you do in these videos requires a much greater level of understanding - one which I haven’t managed to achieve quite yet. Like you, I need to keep studying. Keep it up!

[@ScienceAsylum]

It took me a long time to get here. Your teaching career is going to help _a lot_ with that. I learned more about physics and about people in my first year of teaching than I did in my 7 years at the university.

[@canufen7350]

I admire those who wish to teach physics and i must say, although i may be a year late, many teachers will neglect their given ability to simply watch youtube to obtain knowledge for their teaching, but you however seek more information to improve yourself, I trust that your gratitude for this channel and the interest you have in his relaxed and methodical communication skills will lead your career to be more attracting and successful. But i want to point out to you that using methods like he does or explaining things like he does or channel's similar to this and Kursgesagt, etc, is something students would enjoy more than Anything. I remember in my school during my last years there were a few teachers that decided to do this as well, however the students seemed to come from the depths of hell, and the teachers would leave the next year. I want to give you the advice that if you haven't settled your teaching position already, just always be aware if the school your applying for is worth it, seeing a teacher being used for their kindness or skill is something i've come across one too many times and i especially don't want the same to happen to you. I do believe that you have your priorities straight and you're probably aware of toxic, bait and switch systems that employer's can use, but i'd rather inform you even when it's a bit late, just in case because i admire your perseverance. I hope you're doing well and that everything i said wasn't useless.

[@localverse]

Four things... 1) If we are living in a simulation, the simulators solved the 3-body problem 😄 2) Which part of spacetime is curved more: space or time? 3) Asked #2 because it's weird to think of overlapping curvatures, for example any orbiting satellite will be in the curvature caused by the moon, while both are following the curvature of the Earth, while all three are following the curvature of the sun, while all four are following the curvature from the galaxy's center... so how does that even work? (How does one curvature override the other) 4) So does the Mercury discrepancy also eliminates the graviton theory? Awesome video Nick!

[@ScienceAsylum]

1) Maybe they just solve them numerically like I did for this video 🤷‍♂️ 2) Since massive things move more through time than they do through space, they're more affected by time curvature. 3) It works just like you've described. It's just that we can't write down the math for it on paper because it's too complicated. 4) No, gravitons are still possible. That's a completely different model for gravity, one that works with QFT. The problems is we've never gotten any of those models to match reality.

[@localverse]

@@ScienceAsylum Ah it makes so much more sense that mass is more affected by time curvature... so THAT'S why those diagrams are wrong that show a dimple in space, causing so many misconceptions! #4: Oh wow I thought gravitons were only compatible with Newton's gravity since it seemed to only offer a mechanism for gravity's 'force'.
