## Do you get taller if you go to space?

Astronauts in space can grow up to 3 percent taller during the time spent living in microgravity, NASA scientists say.

That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. … And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
