Guided tours

Three guided tours

Each tour is about 20 minutes: a string of labs that answers one big question, one prediction at a time. Pick one, or explore on your own.

🧩 Tour 1 · The puzzle of time

If you want the big question: why is there one time, and only one? From 'do clocks agree?' to 'is it a law of nature?'

🚀 Tour 2 · From the ISS to the edge of the universe

If you'd rather start with astronauts and spacecraft — then zoom out to the edge of the universe, in space and in time.

⏳ Tour 3 · Is time travel possible?

If you'd like the question everyone asks first: into the future, into the past — what the physics actually allows.
