Begin the voyage →The real solar system, computed from orbital mechanics. Scrub time and watch the maths.
Run the simulation →Five questions, one round a day, same for the whole planet. Build your streak.
Play today's round →Put Earth next to the Sun. Then next to a black hole. Watch your brain give up.
Compare anything →Black hole, light-year, quasar — every space term, explained like a human.

The Carrington Event made auroras glow over the tropics and shocked telegraph operators. A repeat today could cripple power grids and satellites worldwide.
