Yıl olmuş 2018 ve senin türün hala oksijen tüketiyor. İngilizcen yoksa çevirisini oku, buraya da video linki bırakıyorum, algı yeteneğin + muhafazakarlık seviyene kalmış gerisi.
It was, indeed, waving. It just wasn't waving in the breeze because there is no atmosphere on the moon.
The flag they put on the moon has a metal rod running along the top, and when Neil Armstrong pushed it into the ground, he twisted it a little, which set the fabric into motion. The fabric hanging down from the rod acts like a pendulum, moving back and forth under its own momentum, restrained by the elasticity of the fabric attaching it to the rod above. The result is that the fabric undulates or ripples rhythmically, while the stiffness of the fabric resisting deformation gradually slows it.
On Earth, things have to be relatively heavy or compact to swing like pendulums, because air resistance stops anything, like a flag, that's too bulky or too light to have enough momentum to push through it. But these images didn't come from Earth.
If there's something counterintuitive about a flag swinging around like a pendulum, that's only because we're not used to seeing things move around in a true vacuum or under reduced gravity (or, for that matter, seeing flags attached to rods on two sides).
