Travel: scroll through a living starfield and shifting nebula. Hold W to warp. Scale of the universe: slide from a hydrogen atom to the observable universe and see how long light takes to cross each size. Time dilation: approach a black hole and watch your clock fall behind the one back home. Try the Miller's planet preset. Wormhole: steer the tunnel with your pointer, hold to dive, and emerge near a different galaxy. Gravity sandbox: throw planets, plant stars and change the strength of gravity. Drake equation: adjust seven guesses and see how many civilisations might be out there.
