How is the dust changed by the impact of the air particle. Does it change direction from impact? Does it do anything to the wall of the particle that it hits with high speed impact? I don't know exactally why I am even interested it is just curosity of the insane.I am just thinking about all the different particles that are constantly bombarding each other and the actual effect. Does the speed of the particle's movement create any energy?

I read that stem cell research is "promising", but has anything been cured using this yet? It is talked about like it will cure everything, so I was wondering if there were any usable cures.
And why does the government need to invest in this? If this is so promising (and therefore would be profitable for the discovering company), why do we need to spend government money to fund it?

Do we know if the smaller particles that bounce at random as you might assume, off of the dust particles, increase in speed or decrease when they hit the dust? Is there a way to determine that speed or is it random too? I guess it would depend on the density of the dust, right?
