What If You Could Travel Between Worlds?

What if a door could take you to any world in the universe? One step and you're under two suns. Another step and you're standing on an alien ocean. But every world has a price: crushing gravity, air that boils your blood, and a clock that runs differently from the one back home. One hour there could cost you ten years on Earth.

Science notes: Kepler-16b is about 245 light-years away and orbits two stars that circle each other every 41 days (discovered by NASA's Kepler mission in 2011). Europa's ocean may hold about twice as much water as all of Earth's oceans, and its surface gets roughly 5.4 sieverts of radiation a day. ISS astronauts lose 1–1.5% of their bone mass per month. Mars's atmosphere is under 1% as thick as Earth's and about 95% CO₂. GPS satellite clocks run about 38 microseconds a day fast because of weaker gravity. Your body carries around 38 trillion bacteria. Astronomers have confirmed more than 5,000 exoplanets. The "1 hour = 10 years" scenario is dramatized; it would take a planet extremely close to a black hole. #whatif #animation #stickman #space #science
