Mark my words, someone’s going to make a video game with 100% historical accuracy with this.
You can automate control of your craft in KSP with a mod. All you need is to have it send the data to the Apollo computer and then send the output to the craft. It should probably work with the real solar system mod.
Now that I saw this though, I swear I saw this exact video already. Scott Manley or someone may have already done this.
If that works with the real solar system mod that is honestly the finest testament KSP can get for its mathematical accuracy.
KSP is not mathematically accurate and it can’t be or it would have trouble running on computers. They split up and use simplified 2 body dynamics in the game.
We use super computers to model the n-body problem bcz of how complex it is.
Of course, NASA ain’t modelling actual missions in KSP.
I imagine KSP is simple Newtonian physics which is accurate at macro-scales, whereas obviously NASA is going to use Einstein’s equivalent. Far more computationally intense but really important once you scale up the small errors in Newton’s equations.
This code was first published 10 years ago, but I haven’t seen any such game yet.
They’ll get round to it. They’re doing the graphics first. They’re currently making individual 3D models of “all the stars”.
I’m not a computer graphics guy, but I wanna math. Theoretically, if I wanted to make the smallest possible 3d model, I would define it as four interconnected points. Each point has x, y, and z coordinates, so each model takes a theoretical minimum of 12 bytes of storage. Someone who knows computers can correct me if I’m off by a bunch.
The lower estimate is around 100,000,000,000 stars in the Milky Way. That’s only 1.2 terabytes worth of my theoretical minimum 3d model. Doable! But you said all stars. The lower estimate is around 10^22 stars in the universe. That would be 120 zettabytes. That’s only a few orders of magnitude off from the total available worldwide datadata storage!
Edit: I might have thought of a way to define a 3D model in just 2 bytes. You need four points that each have values for x, y, and z. They don’t need 256 possible values for those, they can get by with two each. One bit can store two possible positions, so we can use as little as two bytes to define every point’s position with 4 bits to spare. Behold, a tetrahedron:
0000 0100 1010 1110Each set of four digits defines the x, y, and z coordinates for each point, as well as one extra dimension. You could use those extra four bits however you want. An extra spatial dimension, defining a color, etc. The theoretically smallest possible 3D model. Take the numbers I said up there and divide them by 6. A model for every star in the universe, and it would only take 20 zettabytes.

‘Elite Dangerous’ is from 2014.

Remarkable that you can copypaste all that and still can’t comprehend what was done in 1984 and what was done in 2014.
If you find a way to represent our existing Milky Way galaxy with a procedural algorithm and a seed that can be run in a reasonable time on any current computer or even a cluster (say, running for a few dozen years), you’re welcome to claim the Nobel prize.
