If a "humanoid" from this planet visited Earth with 1/6 of their normal gravity, would they be a super athlete, or barely functional?
Or if "humanoid" even makes sense. Something snake like that can spread out the pressure along a longer surface might be better. Or at least something with more than two legs.
I would almost go looking at deep sea creatures that have to deal with extreme pressures on earth.
Weight lifters are able to lift 6x their body weights, but it's not a sort of load that we could profitably exist under long term. We'd need to have extremely thick limbs and at some point that won't help either because of the cross-section vs. weight scaling law. It's also a sort of weight where any kind of leverage against a joint will generate massive forces. E.g. try catching a 50kg falling weight, you are likely to dislocate your joints and/or break some bones. And yet 1/6 of that is entirely manageable.
Perhaps we've had it too easy here - moderate climate, oil as an easy fuel source, and gravity that isn't too oppressive. I wonder what technology would arise in a more difficult environment, such as this superearth.
I’m imagining some sort of mega cannon or railgun as a propulsion method to fling them off the planet.
