Did you ever stop to think about what might be possible in
the conditions of less than earth gravity? I have! Let's
take the Moons conditions for a moment. One-sixth of earth
gravity. That means you can jump 6 times higher (about 12
feet). You can land safely after jumping off a platform 6
times higher than you could down here (about 48 feet for me)
and it would take 6 times longer to fall that far!
Let's consider something else. On the moon, since you weigh
only 1/6 of your weight, you could strap on wings (on your
arms) and actually fly. This is of course assuming that you
are in a full air pressure enclosure.
The downward force needed for me would only be about 14
pounds per arm, a good amount of force, but do-able...
Of course, to really fly is not to dead-lift your own weight
with wings, so it shouldn't be all that hard. Control? Now
that would be hard!
I can see it being done though.....
Another thing to consider is the effects of gravity on
asteroids. The biggest one is Ceres, it's 914 Kilometers in
diameter (568 miles). The gravity on this one is only 1/26
that of Earth. Not much, but you can't jump off! It would
be scarey though, if you can jump 2 feet high here, you would
be able to jump 52 feet into the air there!
The smaller asteroids are even more dramatic! But you can't
jump completely off unless they are six miles or smaller (if
you were to jump and run). Jumping straight up means coming
straight down, so even if you can go fast enough to escape
the gravity, this needs to be in a circular motion....
These are but a few of the things you can imagine in a space
environment, and there are many more.....
