Compute the interval for each physics update.
Multiply gravity by the interval of each frame.
Moons are massive.
Add a gravitational constant.
Gravitate! GRAVITATE!
Modified Gravitational Constant / Background colour updates with solar systems
Modifications to a few comments
Gravity is slightly less influential
Added Nebulae

Really laggy…
Slight changes involving solar system and nebula generation
Made Nebula Clouds bigger
Made nebulae less laggy and less circly
Started Work on SPACEShips
Added Spaceships that move
Ships turn smoothly
Groundwork for ship following stuff
Spaceship is now the centre of the universe
Physics managed by the universe not the scene
Pinned HUD system labels to the corner of the screen
Added A SPACESystem class
