What is Electricty What is Magnetics?

Here is where I read that theory about gravity...  just a theory but it makes alot of sense to me.

     I believe Gravity is an effect of a force that is seeking to put all  into a single point. This force is countered by Radiance which seeks to expand all into obllivion.  They are so opposed that perhaps a unifying theory on a mathmatical level would be to just throw a negative into all the constants and give them new names.    
   Since time is energy dependent or is dependent on change I don't really want to see any team win.  Though at 53 I'm getting pretty fed up dealing with gravity.
Not that I want my atoms scattered on the solar wind just a little relief from the single point field would be nice.

Today i was reading an article about static electricity...
This is what it said.....
Static electricity is electricity that does not flow in a current. An electric charge is generated by rubbing two nonmagnetic objects together. The friction between the two objects generates attraction because the substance with an excess of electrons transfers them to the positively-charged substance........
--------
Then later on it said.......
Your new electrons fly over your body because they are looking for a positive charge. If you touch a metal doorknob, the electrons on your body will leap into the metal, attracted by the protons there. The transfer of electrons is actually a small electrical current, and produces the tiny electric shock you feel called Static electricity.

well bugger me....that explains it good.

Now i will tell you how it works....
Rub some hard rubber until it gets hot...then attract some salt with the rubber......now move a salt crystal a bit and there is a good chance it will jump away.

Yea thats a pretty crappy explanation.  I don't know why some people try to act like static electricity is different from the typical battery electricity.  They are the same thing, no difference.  "Static" is just high voltage.  Any high voltage source will make the same "static" that is seen when you rub your socks on a carpet.  The only difference is in the power levels.  High voltage sources will kill you because they have quite a bit more energy behind them.  So when you short a high voltage source, it will push maybe 2mA through your body whereas the static from the carpet will push only 2pA (peco-amps). 

Basically, your body has a certain level of capacitance, which is not nearly as large as a high voltage power supply.  If you had a really good capacitor connected to your feet, you could probably store enough energy to kill someone if you rubbed your socks on the carpet for a long enough time haha.  100,000 volts stored in a 1pF capacitor is way smaller energy (~0.01Joules) than 100,000 volts stored in a 1mF capacitor (~10,000,000 Joules).  When either of those capacitors are discharged quickly, the current produced will be proportional to the amount of energy that is stored.  The pF capacitor will hurt (like the shock from a door knob), but the mF capacitor will kill!!!

Why does the salt crystal jump away from the hard rubber when you move it a little?
Here is another thing...
Rub the hard rubber and attract iron filings with it......then remove the rubber and approach the filings with a steel magnet.....now reverse the steel magnet and approach the filings.....some of them will jump away....
This shows that the steel magnet changed the poles in the filings...so they jumped away..
