Let's reproduce the calculations from Interstellar 

I hope you enjoy this long video, it took a long time to make but I'm pretty happy with how the simulations turned out! If you'd like to take a look at the codes for the simulations (those shown at 5:56 and 13:35), a basic version of each is available on my shadertoy page : www.shadertoy.com/user/aroussel Several people were also wondering about the first calculation if it was okay to estimate the distance to travel by a straight line : while it is definitely not a realistic trajectory, it is still good for yielding a quick order of magnitude. I wanted to start the video with a very simple calculation, similar to the rough estimates that are used in astrophysics. For those interested in the full calculation, in reality the trajectory would more likely resemble a half-ellipse (see Hohmann transfer), which would be quite excentric due to how far Saturn is from the Sun, and would therefore look pretty similar to a straight line. If we calculate the exact length of this half-ellipse in the heliocentric frame we get 2 billion km, which is 35% off from the result using the straight line. It is of course quite off if we want a precise result, but it is okay in this context since we only wanted to check whether or not the speed of the ship was absurd and unrealistic.

Commenting for algorithm. Shame about the copyright claim but hope this re-upload will still reach as many people as possible, because the visualisations and the way you guide the viewers through the problems is simply sublime.

This is the most insane video I've seen on this platform. The amount of calculations, accurate simulations - and the simplicity in presentation is phenomenal.

Sucks about the copyright, this video was really well made and interesting to contrast interstellar physics vs more accurate calculations.

When Veritasium talked about light cones I immediately thought of you and I was pleasantly surprised to see you on that video! This channel is a gift of easy to understand education and this video was nothing but breathtaking

The amount of work you put into making this video is phenomenal. The visuals too were absolutely fantastic. A small gesture of appreciation for all the effort gone in making this masterpiece.

As someone doing his PhD on black holes, I really love your videos. They are really great in helping visualise things. I also love that your videos don't compromise on the actual physics.

Cant believe you had to fly through a wormhole to film that blackhole. Excellent work!

2014???? It's already a decade ago??

I'm doing a PhD in this field, and I aspire to have your communication skills and physics knowledge. And wow the simulations and calculations are breathtaking. You are an inspiration to myself and many others, thanks!

Literally, this is the most underrated channel on the internet. i just rewatched the reupload :D

In the internet where stupid fake science run rampant, you're one of the few who actually put in the work and educate viewers. Kudos, subscribed!

Glad to watch it again. I gotta say, nolan should have kept the black hole (and trinity test in Oppenheimer) as realistic as possible

If I am to trust the "uploaded x hours ago", then this video was literally uploaded within 30 mins of me finishing watching Interstellar. Timing literally couldn't've been better lol

The visuals of blackhole with higher temperature took my breath. So beautiful. Thinking about percieving not an object in space, but an event in time (as said in Veritasium video) with such breathtaking visuals is something beyond comprehension yet somehow poethic.

Well (same as last time) I'm glad I watched a commentary review about the realness of the visuals of a popular space movie. Good work.

This video is incredibly underrated. It's one of the most remarkable ones I've ever come across on RU-vid. The script, editing, and dedication displayed in it are simply enviable.

I read the book Science of Interstellar a long while ago when it came out, and wow!! I'm amazed with the animations in this video!

8:29 I didn’t know the DMV was near a black hole

The quality of this video is just outstanding.

Criminal that this doesn't have more views when channels like Veritasium show that people enjoy physics content. RU-vid sort out you're algorithm!!! Amazing as always!

Yours is a unique channel, with the kind of a content that cannot be found anywhere else! Truly a treasure and yet freely available! Feeling grateful!

RU-vid copyright system going at it again 😢 Amazing video, hope it blows up as it should. I particularly love the visualization of the inside of the wormhole. It think it looks so much more mesmerizing than the one in the movie.

This continues to be my favourite RU-vid channel. The visualizations are breathtaking now, but they are only beginning to catch up to the level you are on regarding knowing exactly how to describe things to your audience to bring topics into grasp which other educators have failed to breakdown in such an accessible way. I have learned so many things from you that I figured I would never learn without an in depth understanding of the math. Thank you so much.

Please please PLEASE include a music list! Your backing theme choices are excellent!

This video should be part of Interstellar extras, despite copyright violation . Excellent job!

This video is not youtube worthy!! I don't understand much about physics (especially all the formulas), but the visualisations are outstanding. thank you

I haven't even finished this yet, but felt compelled to express just how amazing this video is. Everything, from the visuals to the explanations, and especially how seamlessly you weave them together is honestly one of the best visual depictions I've ever seen for content like this. Even the way you animate the equations and plug them into others, while not detracting from the visual simulations is just flawless 😮

Your physics videos are just amazing. You make the toughest physics concepts understandable for everyone. You are not just a science communicator, but also a science influencer. The content you make and the aesthetic and everything is going to drive so many people in studying astrophysics. Love watching your content.

The way you simulate and explain is much more comprehensible any other videous on youtube. Your explanation with combination of spectacular simulations are realy fascinating stuff.

I had a feeling some details in the film weren’t accurate when I saw it, really glad you made this video doing all of the calculations!

this video came out on my birthday-interstellar is my favourite movie and you are one of my favourite channels. i was so excited to see you talk about the physics behind it, and it made it even more credible that you relied on kip thorne's book. so thank you so much for this gift! ♡

I'm absolutely stunned by the simulation of the interior of the wormhole, and the reallistic simulation of Gargantua is just so beautiful (given I like blue a lot)

Cooper's Station is by far the most unbelievable part of this story. Not because of its questionable feasibility, but because of the damn housing. This is a station clearly modeled after cylindrical space colonies dreamed up in the mid-century. Space colonies meant for alternative living around a still mostly livable Earth. Not interstellar arks housing the last bit of humanity clinging to survival at all costs. Why on earth would they waste valuable square inches on traditional suburban homes? Otherwise, good one Nolan.

I've been subbed to this channel for a while now and literally injected all content into my veins immediately. Glad to see it's still going!

What a terrifyingly beautiful visuals. Hats off to your effort for the rigorous calculations and simulations. Such a treat to eyes.

Watching again! This video is kind of incredible! Great job!

Your effort and skill are definitely noticed… great video! 👏🏻💯

This video was absolutely amazing. Thanks for all the awesome work. My new favorite channel :). Gonna go binge watch the rest of the channel.

For so long I’ve been looking for these kind of breakdown videos. Thank for giving me this opportunity.

Always very high quality videos! Thanks

Commenting again - thank you for the longer video it’s superb.

This is fantastic. Thank you for taking the time to make this clip. It must've been painstaking to say the least!

This is the best visualization of black holes I've ever seen period. Direct simulations from General Relativity aren't exactly a piece of cake, I applaud you. Thank you so much!

Repeating my questions from last time (with answers from scienceclic) They would do a hohmann transfer rather than direct flight, but they had some martian and julian slingshots so a direct flight was an estimate for not absurd numbers. The baseball's arc doesn't match it going into the simulated gravity of the other side of the toob.

This is a true masterpiece, just like the movie itself! Would you be willing to share the black hole simulation codes?

One of the most amazing projects I have ever seen. Please upload an article including some of these visualizations and more technical explanations!

Love watching these kind of videos, just theories and calculations on such complex matters are oddly relaxing to listen and/or watch

the reupload gave me an excuse to watch it again, great video!

Could the planet Miller not be seen due to the extreme temporal dilation that would cause redshift out of the visible spectrum? (when the astronauts were far from it)

This was extremely good. The amount of effort put into this was astonishing. This deserves much more views.

This video was unbelievable and a visual delight! Thanks for making this, and I'm looking forward to seeing more from you!

Ah what happened to the original? Either way, the visuals, the explanations, all top notch as usual!

Thanks!

This video is extremely well-made! I've never seen such a clear & detailed discussion of modern theories about what happens inside a black hole.

I watch hours of science and Astronomy videos everyday and this video is truly one of the most breathtaking videos I’ve ever seen. The simulating black hole section is a masterclass of presentation blurring the line between science and artistic presentation that is mesmerising and deeply disturbing at the same time. Thanks to all who made this video possible.

As I write this, it is NASA Black Hole Week 2024. We've already had (just last week, so slightly early) Veritasium (using some old 2021 ScienceClic footage) doing a video on black holes, PBS Space Time starting a small series on one aspect of black holes, and (on Monday) NASA Goddard showing a new supercomputer simulation of falling into a black hole. And now, on Tuesday, this. Twice. Including this comment, twice. (-: Followed by ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WESb6MDXqkQ.html which is just the simulations from this video without the mathematics and commentary.

this was incredible! keep up the good work!

This channel and video are absolutely brilliant and a gift to science communication that keeps on giving. Thank You Alessandro and team for your exceptional work.

Holy crap this video was WAY more interesting than I thought it would be. Commenting so the algorithm picks up this amazing content. Love your work, man

Wait what? Is this a re upload? Edit: just saw pinned comment. This video was absolutely incredible btw

Watched it before, commenting to boost

Always thrilled to see a new upload from your channel!

Very detailed yet easy to understand explanations and calculations and stunning graphics! Thanks for your video!

Veritasium 3blue1brown and Vsauce are in big trouble

Just Shut up and take my money 🤑💰👍!!! Loved every bit of Interstellar and of course also love literally every single video from this channel 🤓👌💯

Interstellar is such a gem, both breathtaking and very scientifically accurate (with some inaccuracies that can easily be forgiven). I'll never forget the experience of seeing that movie in cinema for the first time. And your channel is so excellent at visualizing all those difficult topics such as space curvature around wormholes. So good.

Thank you ScienceClic for your amazing videos! You bring incredibly complex topics to everyday people, making things easy to understand. Phenomenal work once again! Looking forward to what you make next!

Just missing the Doppler effect (blue on one side and red on the other) :) 🔴🔵

This is so cool

what are the odds i literally just watched this movie (bawled my eyes out multiple times), and stumble upon this video always love how well you explain everything

just amazing, you're on the top quality youtube videos, please keep doing this, your work and time will be rewarded Im sure

Your video definitely seemed like fair use to me, hope this works for you though :)

Have a comment. It's the least I can do. Literary.

Superb. Your skills in turning mathematical models into visual representation is breathtaking. And it is not only that video but all from past when you were presenting General Relativity. Thank you very much!

I love your video that explains several mathematical and scientifical calculations related to Interstellar movie. I haven´t seen the movie yet but my fascination for this topic has increased. I am following your channel. Thank You !

Thanks

A repost? So, there was any issue with scenes from the movie? I liked that edit from a day ago.

Hat's off to great level of details you work on practical and very complex things which look so mesmerizing... ❤

This channel needs more views, i've followed science channels for a long time that have been explaining the same things over and over but it wasnt until i saw the videos from this channel that i ended up truly understanding some things.

Reupload?

Deja Vu all over again ..

this video is a great example of why interstellar is my fav movie of all time it does its best to be realistic and accurate to real life but isn't afraid to take some creative liberties to enhance the story yes the time on miller's planet isn't realistic, but the time pressure and how it was portrayed in the movie for sure makes up for it

This movie feels like a really big and long space simulation, but with a little plot sprinkled on top.

For the Algorithm!

WE ARE SO BACK🔥🔥🔥🗣🗣🗣🗣💯💯💯

How about that. I absolutely love Interstellar, worked as a 3D artist for several years and now as a software engineer for the past four years. So this video is incredibly interesting to me, thanks so much. So cool to see the calculations and creation of the visuals. Oh, and to be honest I actually prefer your visuals over those in the movie.

I always trust your videos. You are my favorite science RU-vid channel and I aspire to understand physics half as much as you do in your profession. Truly, admirable

There is no such thing as a singularity in reality.

I’ve been binging this channel for days now and I can’t believe I have the privilege to be consuming this content for free. You’ve made so many theories and topics “click” for me and have given me so many “aha” moments because of the impeccable visuals while you are explaining. It is an honor to be subscribed. Thank you so much 🙌❤️

Loved the video! Insightful and a delight to watch!

Commenting for better reach! This is an underrated channel that needs a significantly broader audience for the efforts! Kudos to your work. 🎉

I'll take the reupload as an opportunity to just watch the whole video again lol, amazing stuff and stunning visuals as usual. Thank you for another amazing vid!

I've been looking for a video like this for years!! Thank uuu

This video is the most amazing Astronomy & Astrophysics video I ever seen in a long time.. I love the theory explanation

We need this kind of channels that provide genuine Science education. It's pleasantly refreshing to watch this kind of video out of all other channels that do nothing but stitch random space videos and pretend to talk and predict science. This man deserves a standing ovation!

There is one thing that you may have missed with the simulation of the appearance of the wormhole. The camera is inside a spaceship. You are treating that ship as invisible. There is a path from that ship that travels around the hole and returns to the ship. I think from the camera's view of the wormhole, it would add a very thin ring where the two sides of the hole touch.

You really put a huge effort for just this single video. Mad respect

This has to be the visually insane video I've seen. Especially when you raytraced a black hole to show how it would visually look. My god, I can't even begin to imagine how it would look like being so close from within the planet. Absolutely phenomenal.

At 5:56, I'm guessing that reflections of the spacecraft should also appear at infinity in all four directions, slowly converge on the spacecraft and diverge back as it exits the wormhole (because there will be light rays that are reflected off the spacecraft in the direction of the cross-section of the wormhole and will thus travel in a loop). One can imagine a wormhole of too little diameter being crossed by a ship which is then, at the middle, crushed from both sides by itself!
