Trippy!
scottEkarate
Build a space tether
mercbrit
I don’t know what that is but it’s not a carbon nanotube is it?
BukkakeRider3000
So, can we now have the space elevator?
SallyMcCrumbles
No
Asikar
not in earth's gravity, possible on the moon?mars tho
VosperOfAntarctica
Car Banana Tubes?
DnZeroes
I'll take one.

Real question cuz I'm not a scientist: would it float like this in a vacuum?
peterbozeman
Negative.
Gin3r1c
Uhhh nope
HardyandRamanujan
No. Floating means that the floating thing has a density less than the medium it is floating in (simple explanation). No air, can't float
HypnagogicHallucinations
That's why nothing in space floats.

That's a good question. It is a very small mass relative to it's surface area. It's not floating like a lighter than air balloon. It's just
that the browmian motion of the air is enough to push it around, offseting the minimal gravity. This suggests in a vacuum it would fall.
I could be wrong, and the material itself could be lighter than air. Dont think so, but that would still result in falling when in a vacuum.

Thanks, I was genuinely curious
