Floating Dust

Why doesn't the dust stay in the air longer than in earth? Surely with the less gravity it would float around for ages?

This is one of the most common reasons for confusion and claims of hoaxery. Let's get straight two basic facts;

• 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.

These two facts make almost dead certain proof of a lunar landing. There is absolutely nowhere on Earth that you could make dust behave in this, to us, peculiar way. If you were to create a vacuum on Earth, the dust would fall very quickly, just as we are used to a rock doing.  But here is evidence of dust behaving like it's in a vacuum and in low gravity. Without modern computer movie graphics there is no way this could be faked on Earth.
