If I push one end of the rod, theoretically, the other end instantaneously move away from me as well.
Actually it won't since in pushing the rod you are using the electromagnetic force between your hand and the rod to do the actual moving and it does not travel faster than light.

I just happened to be doing some study of my own in physics today.I am trying to catch up on the science I did not have the tenacity to deal with in High School and at the age of 47 I am for some strange reason catching a bug for understanding how the world is put together. The things I have not percieved before continue to stagger me. Today I actually read a new take on something I had heard before but did not really appreciate.
An atom has a diameter of about 10* -8 centimeters. The nucleus has a diameter of about 10* -13. If we had an atom and wished to see the nucleus we would have to magnify it until the whole atom was the size of a large room and then the nucleus would be a bare speck which you could just about make out with the eye,but very nearly all the weight of the atom is in that infinitesimal nucleus.
And then to think that the electrons in the probability envelope around this tiny nucleus are responible for the entire array of chemical and biological actions and reactions throughout nature is stunning.From the color of rainbows to the hardness of diamonds, the electrons do all these things. It certainly takes your breath away.
I do not have regrets but there are times I wish there had been more time and less responsibilties in my life so I could have pursued these wonders.I envy the young man{and woman} these days in the access to knowledge and real concrete understandings free of superstition and myth.

Have you ever seen Powers of Ten?

There is an article dealing with mesons violation of Bell's inequality at this site. Home – Physics World
I will try to stay clean away from the issue as it deals with quantum mechanics and is slightly {LOL} out of my league,However I was always curious about the action at a distance idea. I remember reading once that due to relativistic effects a photon travelling at the speed of light,even though it is a finite speed,experiences no passage of time on any distance it travels in it's reference frame.Since space and time are bound at the hip so to speak does information transfer in our frame of reference somehow produce the appearence of action at a distance where none exists for the particle involved?
This is no doubt wrong but I need to have some idea of where it is wrong so that I can move on to some other idea.
