Mass killings

    Why is anyone shocked the acts of an obviously evil man. It's a sad day when you send your happy cheerful child to kindergarten and return to find out a madman went nuts.

     Obviously there is no way to console anyone who experiences such a tragedy, but we all know that no one needs  an AR-15 or Sig Sauer assault rifle, now if he got off one hundred rounds " which has been reported". It's not likely he did it with two handguns. These weapons are made for war and nothing else. So there are only two ways to approach this.
1. Ban civilians from purchasing them, because no one know's who will snap at any time, it's unpredictable.
2. We wait until the wrong person get's killed and the pendulum swings completely in the opposite direction.
Now I understand it's interpreted differently as to the Constitution But when the Constitution was written they didn't have guns that fire 500-1000 rounds in a minute.

    I am a card carrying member of the NRA, so I'm not asking to get rid of private ownership, but if you think about it, it's kind of cowardice to use those types of weapons against civilians. It takes no skill, all you're doing is spraying people. It takes skill to use a handgun or a rifle. The ideal weapon for home protection is a shot gun, any officer will tell you this.

     So who or how many deaths will it take to end this madness. Law makers aren't concerned enough about the welfare of their constituents. My prayers go out to everyone who has been affected by this tragedy.

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.
