Why doesn't the dust stay in the air longer than in earth? Surely with the less gravity it would float around for ages?
[...]
* Dust does not float in a vacuum. The only reason it 'floats' on Earth is because of the air that surrounds it. In a vacuum dust behaves exactly like any other object. You throw it up and it will then fall . It is no different from what a rock would do. Rocks do not float or billow around nor does the dust, even if it is lighter.
* Because there is no air, dust falls quicker on the moon than on Earth. This may seem strange, as the Moon's gravity is much less. But the lack of an atmosphere is far more significant to the dust. But it still falls slower than you'd expect a rock to on Earth.
