Gravity

     Why is it that in space small particles such as salt and sugar will clump together? Large bodies such as the moon and earth effect one another as well.

     Well then you may ask why do some meteors hit Earth and others merely skip off the outer atmosphere despite the disparity in mass, well I think it's partially due to trajectory but I also believe it has to do with the proximity to the planet. In the recent past we have had a few near misses.  Some that were visible with the naked eye, yet (luckily) they didn't hit us, why?

     I don't think it's gravity ( alone ) pulling or pushing the penny from the table to the ground when it falls from a table. It falls because there is no medium to stop it falling. Had the Astronaut put a penny in with the sugar and salt experiment aboard the ISS I'd wager the penny would not have clumped up with the particles, they may have clumped to one another and then to the penny but not vice-versa.

     I think that there is a proportional value of mass and trajectory ( possibly other factors ) that determines what we call gravity. Now as I have said before i'm not a physicist or a mathematician, just a guy with idea's. Perhaps this view has already been put out there, I'm just putting forth an idea I haven't read about or seen on one of the science channels. Maybe it's valid and someone can do something with this to answer some fundamental questions about the nature of gravitational fields both on a universal and the sub-particle level.
