Gravity close to Earth's, at 1.0 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.

Hear how a voice sounds herea computed acoustic demo

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, 1.05 times, so you would move much as you do here.
