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 😉
So you’re saying, what the squirrel had for breakfast will alter its relationship with the “black hole” version of earth?
How would a Many Body Problem look like for non-Planar Orbits of {3or 5} BlackHoles
I have a question I have been wondering for a while now. When a electromagnetic peak meets with a troupe where does the cancelled energy go?
@@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. This will not happen if the objects are far apart, but then the nature of the object doesn't matter anymore either.
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".)
For now on, every time a rocket in kerbal space program fails it was still a successful orbit
Yep .... it's _soo_ unfair whenever the ground is allowed to interfere with what would otherwise be a stable orbit. Stupid ground.
But doesnt the atmosphere and you know the planet also effect the trajectory? Therefor making it not an orbit by definition?
Vatsyayana weren’t you listening? As long as GRAVITY is the ONLY influence... it is an orbit...
@@pauligrossinoz make sure it just clips through the earth and you're all good
And as Douglas Adams once so aptly put it in the Hithchiker's Guide....
“There is an art, ( it says), or rather, a knack to flying. The knack lies in learning how to *throw yourself at the ground and miss* … Clearly, it is this second part, the missing, which presents the difficulties.”

What about Veritasium and Sixty Symbols?
Veritasium
True
No One:
The rotating blackhole non planar orbit: Weeeeeeeeeeeeeeeee!
Sisyphos: "Gravity sucks"
Burned squirrel: "You have no idea ..."
Yes, I was surprised. By the 3 body free falling orbit.
I was like "woah, living on such a planet must be interessting", but before you said it, I also thought "and that's never gonna happen due to all the other stuff flying around. No way this is stable enough for billions of years".
True. It would have to be a _very_ isolated system.
@@ScienceAsylum Never ending space roller coaster
@H K i read somewhere the universe isn't infinite "only" 250 times bigger than the observable universe, but how can they prove this? I have absolutely no idea. If the universe is truly infinite tho, any and all patterns would repeat themselves, however complex they might be. So yes in that case there must be an infinite number of these system, an infinite numbers of solar systems exactly like ours containing an infinite number of earths exactly like ours, with an infinite number of you and me- typing this exact thing an infinite number of times. Simplified: "everything that could have happened wil have happened, and everything that can happen wil happen an infinite number of times" (Sry about the long reply)
@@BenjaminBjornsen 250 times is the minimum, assuming the universe doesn't have a weird shape.
@H K Yes but it might take you an infinitely long time to find one.
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.
github?
Jack CF can you please tell me that app name
Github please?
Cool!
I've done the same almost 33y ago on a Commodore +4. It was not really fast but it was able to simulate in 3D in a reasonable speed almost 10 object and it was amazing to see those objects zips around the screen, some in a kind of stable orbits and some going somewhere outside the screen limits.
Some day, Question Clone is going to steal your lab coat and impersonate you.
I've got my eye on him. If I'm being honest, Nerd Clone is more dangerous. He already vaporized at least one clone that I know of.

"Whatever 'this' is"... I love science jargon! 🖖

Let's call it ξ (xi) ...
This is your best video so far. You introduced just enough jargon so that we could understand what you were saying without going overboard.
Thanks! I'm always looking for that balance.
True Alexander
i keep orbiting this channel and whenever there's a new upload, it's straight free fall
It feels criminal that I didn't discover this channel until recently. It joins the likes of Vsauce, Veritasium, Numberphile, and MinutePhysics for my favorite math and science channels. I will probably end up watching most of your videos a ton of times each. I love rewatching educational content.
Glad you found us 🤓
Gonna sound like a nerd, but: Edutubers are the best CZcamsrs!
Another brilliant piece of teaching that actually makes me want to learn more!
Discovered the channel early in quarantine and it's made it a lot more enjoyable 😃
Thanks for all the great videos and please keep it up😁👍
I love how there’s always a cliffhanger feeling to your video’s. That binge watch feeling that tells you: “Watch one more! Just one!”
That's science. You've never figured it all.
I'd been wondering about Moon Moons for a while and if any had been confirmed. Now onto Moon Moon Moons.
unfortunately, no natural moon moons have been discovered as of yet. This is mostly because moons tend to orbit so close to their planets, that the tidal forces make moon moon orbits unstable. There are some examples of artificial moon moons. Some Apollo missions are a good example.
If you cheat by calling the planets the sun's moons, then all the moons become moon moons. Now you're one step ahead.
What if Moon Moons could be found on moon moons?
Would they be moon moon Moon Moons?
@@KohuGaly Some large asteroids actually have tiny moons. No joke. One of the bigger dwarf planets, Haumea, actually has a ring system around it! Also has two moons. Not quite moon moon moons, but still! Crazy universe!
@@utetopia1620 Thats kinda like to go forever. moon moon moon moon moon ... moons
Wow. I knew that there was something that relativity predicted about Mercury that proved to be true but I didn't know what it was. So thank you for presenting it in such a Lucid way.
"Lucid" I see what you did there.
Actually, never heard of free fall orbits, thank you for this bit!
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!
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.
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.
Omg this was so good !! I love your vibe !! The “line” type of orbit really blew my mind
Love this video! Great as always Nick
The most intriguing to me was that 3 body free falling orbits. Very fascinating actually. Most of us are taught that orbits as closed-bodied repetitive paths, but that's just so wrong, fundamentally.
Thanks Nick for shedding light on this. We crazies will bear this in mind 😊
Moon Moon jokes are still alive in 2020, thank you for keeping it real👌👌👌
???
I cannot express how much I love your content. I think that I've already told each of my friends about your channel, even those, who are not interested in physics xD I really hope that one day you'll get as many views as Veritasium for example.
All your videos are to my liking. Occasionally a real brain buster is a good thing.
You just keep doing the projects you enjoy, and we'll keep suckling at the teat of your knowledge.
This was an excellent lecture
I felt like I just watched a 1 hour lecture within 10 mins
Please do some longer videos.
Thanks a lot
Almost clicked next one minute in, but had to stay for gratuitous cartoon squirrel violence. A+
The summary at the end was a nice feature. This video was amazing and brilliant as are all your videos.
Thanks Nick. Feels great to understand something new.
The Three Body Problem trilogy by Liu Cixin is the greatest sci-fi trilogy ever
Great job explaining orbital mechanics, plan to show this to my HS physics classes next year as a part of my gravity unit. Your video provides the reason why polyconic sections are taught in intermediate algebra. Students always complain about learning polyyconics and not knowing the why for and what to do I do with it.
That's great! I'm glad it's useful 🤓
I request science asylum to make a video on polyconics
This was lovely. I'm going to have to make extra popcorn whenever Nick decides to go into more depth about frame dragging. :)
Great video! Orbits around non-spherical objects like asteroids can be pretty crazy as well.
A 1 hour version of zoom whirl orbits would be amazing, the path really was hypnotic.
I always see the title of your Vids and think "yeah I know all about that.." Watch them then think " Wow.. now I know MORE about that.. and Understand it this time"
Well done! I appreciate the work you put into researching this, especially the coding of your animations. You should do a 'behind the scenes' on how much work some of these videos has taken you (like why it took one year for the video referred to at the end).
That "one year" was about 80% research, 18% deciding what was important/how to explain it, 2% actually producing it (for that video specifically).
I don't know but it was ultra supercool to watch , the ZOOM SWIRL ORBIT. And your expressions after that super dope
it's like falling in really nervous and just dodged the problem, like adrenaline rush, those who can feel it by seeing or roller coaster ride which I've not been to more than 2 times I think
So glad I discovered this channel, it deserves more views! Thanks for these great videos!
Question:
Is there a connection between the solutions to the two body problem being conic sections and the curvature of spacetime? I seen to remember vsauce using cones to describe objects moving in straight lines in curved spacetime, but it's been a while since I saw it...
Michael didn't have to use a cone. He could have used _any_ curved 3D shape. My bet is that everyone always uses a sphere and he wanted to be different.
I don't know why don't CZcams support such a good channel , I think this channel deserves nearly 10 million views
I've been following your channel unregularily from the early beginning from a kind of average / mediocre channel to now regularly what it is today. The improvement is truly impressive. What I especially like is your tendency of going from simple problems to generalization and solutions on a more abstract level. You do that far better than anyone else. The only thing I have to criticize is the lack of maths. Otherwise: great development. The time watching you is well spent.
BTW, the last episode (before this one) was wasn't weird, but probably the best you ever made.
Love your vids never stop posting
WOAH I've never heard of those crazy orbits around a Black Hole before!
Last video was definitely one of the most complex ones you’ve done but I think those are ok once in a while
Yeah, as long as I don't make a habit out of it.
@@ScienceAsylum But .. (just my experience and humble opinion) .. I liked that video uhm .. how do I say this. It's more educational for me (though I learn something new almost every video .. their all good). But in my experience .. at some point physics can't be explained anymore without making it (too) simple. There's a kinda gap or something.
So maybe .. these more complex videos should be a bit longer? Or in parts? (It's probably hard though. Making people happy with math ;-))
(But I personally would love more of those videos, though I understand the larger audience isn't really waiting for that.)
This GR is series gonna be great!
Wow this channel is now one of my favorites.
Viewer: "I'm bored."
Nick: "Check this out!"
Your content is great. Keep up the good work! One question, what software do you usually use in your simulations/animations?
Usually After Effects, but a lot of the simulations in this video were done in Python (because After Effects has limits).
@@ScienceAsylum thanks! Yes, I use both. Pygame for creating graphics in Python?
@@ScienceAsylum did you ever try Universe Sandbox?
@@heliumhydride Nope. Just the visual package add-on.

Amazing as always
**looks at that last black hole orbit**
Hmm... that's the first time I realized black holes were actually black cats playing with a ball of yarn.
What I took from this vid...
"Moons can have moons... We call them moon moons" 😂
I love science... always learning something new or knowing something better then yesterday
I love your videos!
I had no idea a zoom wirl orbit was a thing
And I can't even think about that last one
Speaking of black hole light orbits, I've often wondered whether, in principle, you could position your spaceship at just the right distance from a black hole to fire a laser against its rotation so that the light comes back to you with more energy than you emitted. Just from the exchange of momentum I mean.
I don't know about _against_ the rotation. That's not even possible inside the ergosphere. I do know that we can use light to extract energy from a black hole. That's a real thing. The black hole's spin would slow down as the energy was extracted.
@@ScienceAsylum I said against by the simple reasoning that if you rob angular momentum from the blackhole, then by applying the conservation of momentum, energy must be imparted into the wavelength of the light.
It's just the childlike reasoning of an interested layman, I've no doubt you're right. :)
Kurgesat has a video about that.
The legend is back
Not as weird as the drug dealer’s Orbit around my neighborhood.
There is no need to be so hyperbolic.
Last two were new to me bro. Thanks
Cool video. The behaviour of light around black holes was recently discussed on the weekly space hangout, nice to see it here. Thanks! Another topic you didn't cover is planets around double stars. The different stellar masses must have an effect, but there are even some which safely pass between the two stars. Of course there are also triple star systems like alpha Centauri.
"how can a path that ends be an orbit"
Just wait for the sun in a few billion years
I don't have that much time to wait, let's just watch things smash in Universe sandbox 2
Amazing point
Strictly speaking, it will be the sun that swells up to MEET our orbit. But point taken.
how is this not a 1 million subs channel!?
Because it's neither about cosmetics nor about a cCT.
Excellent, Keep It Up!
I HAVE BEEN WAITING FOR THIS ALL MY LIFE!
Yep
Me too!!!!
I still wonder to this day why teachers don't teach us "how to find earth's orbit mathematically"?
@@bk-sl8ee maybe cuz they don;t know themselves
Yes, this episode was perfectly dumbed-down so an armchair enthusiast trogolodyte like me could still feel smart after watching it. 😋
All your videos are awesome. No exceptions.
Another amazing video. Kudos Nick. My question for this vid is where does dark energy come into the picture when orbits are concerned? Does it impact at all theoretically?
I can't understand your video by watching once so I download it right away. In quarantine I watched it more than 10x times . Now I feel I know more in quarantine than in my school year. For First time I do not wasted my holiday.
Thx for making an orbit video has not seen one before thx.
I didn t react yet to the previous "difficult" video but liked it a lot, I just need to revisit a few times more to turn my gutt feeling that ubderstands it into comprehension ... I do hope you will keep making videos that require some more effort too. Warmest greetings, Ronny.
No one scared me away from them. I just need to spread the harder ones out a little bit.
never heard of a free fall orbit before now. i learned something, thank you!
Thanks a lot for this video. Some of these orbits reminded me of the spirograph toy which I liked to play with when I was a little boy...
Your a great teacher. Thank you
We missed your videos the best teacher👍
Watched the spaceX - NASA streaming today... this video just came in even nicer than usual!
Great vid!!! 👍
Awesome, love your videos
I have said that before but one of the most underrated channels!
How does this channel have only 500k subs?!?
