SPOILERS AHEAD!!!

Sir, please tell me what you think about interstellar trying to be all science and stuff and then ending up with love as a force of nature that "crosses dimensions". Also what does the physicist turned programmer at molly rocket thinks about this. With a science advisor who is an actual physicist and actual papers being published from the black hole renderer made for the movie, all they could come up with was love? Why is the concept of love so important to these people. Can't a guy get a break even in a scifi movie? I think this is the paper they wrote: https://iopscience.iop.org/article/10.1088/0264-9381/32/6/065001

I am no longer in university and can't really access that paper without paying. But here is the arxiv link: https://arxiv.org/pdf/1502.03808.pdf

I wonder if you can actually get your hands on the DNGR algorithm they developed and see if its even worthy of being made so much noise about even as software.

But my question is, why would you do this? Does it really matter how you render a blackhole that appears for a few minutes with accuracy if you are going to just abandon the sci-fi for what I think is closer to fantasy anyways? Its not a bad thing. It looks pretty. But why make a big deal about it? I guess I'm just saying that these people tried to sell the movie as being hard science fiction when it really isn't that. It happens again and again in scifi movies like ex-machina, Transcendence, HER. Please watch ex-machina too. I remember it was shown in our university in the arena and at least 1 computer science student was absolutely awestruck with it. And again, I felt like it was a nice story if I didn't try to question it, but just that. The Martian (Andy Weir) in contrast was a nice story (the book). Every seat grabbing incident in it is based in what at least seems to be plausible science and it doesn't try to masquerade as a sci-fi story while actually being a fantasy story.

Look there are other simulations done by previous researchers on simulating what it looks like near the blackholes: https://www.youtube.com/watch?v=XLPePyDhKIw as mentioned in the paper itself.

I don't get the hype about the visualisation.

They could have said that they found a closed timelike curve and then explored what could be done in a universe that has them. Kip Thorne could have certainly told the writers what can and cannot be done with those: https://en.wikipedia.org/wiki/Closed_timelike_curve

Kip Thorne literally studies time travel. He has a nobel prize in physics. These guys hired him. How does one go that far and come up with the love solution?!

BTW google images of kip thorne. The man has a beard that looks like he is constantly sticking his tongue out like kiss.

look in 1979 this guy already had what you see in the movie. Also from the paper.

Just to pour even more water on people who get unjustifiably excited about the rendering of the blackhole in a "very scientifically accurate" way. The program had a bug. Page 16, section 3.4 of the arxiv paper link. They do say, it doesn't have any impact on the images shown in the movie. But thats my point. If you just paid an artist 500$ to just render some imaginary thing in blender I wouldn't have given any more or less of a damn about it!

It turns out that the movie makers indeed used artists to make the thing you see in the movie. AND what you see in the movie doesn't really match up with what happens in real life at either the theoretical level or (what seems to be more experimental) level image collected using telescopes. I say what seems to be experimental because that image was constructed computationally from a giant amount of data collected using telescopes so there may be bugs in it too.

Also a summary about creative freedoms taken in the interstellar production: https://eventhorizontelescope.org/faq/how-realistic-are-movie-depictions-black-holes-eg-interstellar

I have tried but I cannot find the source code for that paper.

From the book "the science of interstellar" describing the warping of spacetime around the sun:

>How can space “bend down”? Inside what does it bend? It bends inside a

higher-dimensional hyperspace, called “the bulk,” that is not part of our

universe!

Oh you will hate this line so much if you did a course in general relativity. I was a really bad student. But I took those courses just to find out how exactly you get to space bending into another universe. And the short answer is that you don't. These kinds of statements will only be found in the books and articles directed towards the general public. If you wanted to actually dig in and find out the real math that shows this stuff you will just find that much of these things are interpretations of what the equations say. And what the equations say is that there is a tensor that describes the metric in spacetime that you integrate over a path to get the distance between those points. Maybe its just because I am stupid, but man if you are as stupid as me you will get so disappointed 😂

The two best things about Interstellar are the ray-traced Kerr (spinning) black hole with its accretion disk and the soundtrack. It would be fun to do a Handmade Hero stream on doing that with compute shaders! Here is my version of a non-spinning one https://github.com/fernand/schwarzschild_raytracer https://www.youtube.com/watch?v=jDqnRs_xTWQ. The spinning one is a bit more work, but not too bad.

Oh wow! That is super cool! I don't think I would be the right person to do a stream on that, though, since I do not know anything about relativity :)

Friendly reminder: as per the entire point of Molly Movie Club, discussions about things external to the movie are not allowed. I have revised the About page to be even more explicit about this since there was some confusion (https://www.mollymovieclub.com/about).
