| Sorry if this has been asked before (couldn't quite find anything)!
So, how procedural is SpaceEngine? How is it possible that I can fly to some random galaxy to some random solar system to some random planet and can send those coordinates to someone else and they can see the EXACT same thing I can?
If it's procedural then shouldn't that mean that EVERYONES universe is different? If it isn't that procedural then how is having every planet in every solar system in every galaxy even possible in a 1.3GB game? That would be an extreme amount of data would it not? This game has to have billions if not trillions of solar systems within itself...how are all the planets and what not the same between everyone?
I don't know...I'm just confused...can anyone explain just how this is possible?

| The seed used to generate the procedural worlds is the same on all systems, so the same stuff will generate on all computers.
In Minecraft, if you type a map seed on one computer and the same map seed on another computer, the same map will generate. It's the same idea.

| Well how is that even possible though? How can a single seed generate the exact same planets in a universe that has trillions of them?

| To break it down simply: everything is just a series of mathematical equations and expressions. As with any case in math, for any given input you will always get the same output. For example, if x=14, then x3 - 4x + 7 * (1/x) will always equal 2688.5, no matter how many times you calculate it. Anyone who tries to solve that equation for x=14 will get the same result.
The same is true for procedural generation from a fixed seed.
