Wonder & Time — Play

Lift a clock in a gravitational field and it ticks a bit faster. Raise Clock B and see the drift accrue as microseconds per hour.

Try it: Lift the clock. Watch time drift.

If laws can evolve, novelty belongs at the center. This automaton slowly changes its own rule as you scrub time—so the future isn’t just repetition.

Try it: Scrub time. Watch rules learn.

Lightman’s fables turn relativity into feeling. Tap different “city rules” to see how life changes if time sticks, loops, or slips away as you hesitate.

Try it: Tap a world. Feel its rules.

Near the edge, space and time twist. Outside observers see your clock crawl as you skim the horizon. Inside, your watch feels normal—until it doesn’t.

Try it: Drag the ship. Meet the horizon.

Four plausible finales; each sharpens what matters now. Tap to see how a particle field’s fate changes the “arrow” we feel.

Try it: Pick a finale. Read the why.
