Gravity close to Earth's, at 1.3 times. A child would grow up much as they would back home.

A playful thought experiment from this world’s gravity, not a prediction about any real person. No human has ever grown up off Earth, so no one truly knows; the direction (taller in low gravity, shorter and stockier in high) follows how growing bodies respond to weight.

Your voice would sound much as it does on Earth.

We do not yet have a temperature for this world, and its atmosphere is unknown, so its acoustics cannot be modelled. In Earth-like air a human voice carries as you know it, and without the temperature that is as far as the physics will take us.

Recommended, with reservations
  • Surface gravity is close to Earth's, 1.29 times, so you would move much as you do here.
