Making an N-Body Simulation

Making an n-body gravity simulation without wasting any time. After this 9 minute tutorial, you should have all the knowledge you need to make your own basic n-body simulation in your preferred programming language and most importantly, you might even understand it.
I try to keep my videos relevant, no matter what language you use, as long as there's no language explicitly specified in the title. This means that I don't use any hyper-language-specific features and instead try to stick to things that most widely used languages have. This means no specific libraries exclusive to rust and I instead focus on showing code that does what it looks like it does.
