If your children grew up herea playful thought experiment
EARTH HEIGHT≈ 0.95xEARTH-RAISEDRAISED HERE
about 0.95x as tall as on Earth · a 5 ft 10 in adult could stand nearer 5 ft 6 in

A little heavier than home, at about 1.3 times Earth's gravity. A child raised here would likely grow a little shorter and sturdier than their Earth-raised parents, about 0.95x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 6 in, with denser bones.

Bones
Thick and dense
More weight to bear forces the skeleton to grow denser and stronger all through childhood.

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, about 1.31 times, so you would move much as you do here.
