Minute physics: Real world telekinesis

How do magnets affect things at a distance? How does the Sun heat our planet from 93 million miles away? How can we send messages across the world with our cell phones? We take these seemingly simple things for granted, but in fact there was a time not too long ago when the processes behind them were poorly understood, if at all… and, to the uninformed, there could seem to be a certain sense of "magic" about them.

This video from MinutePhysics, featuring director of the Perimeter Institute for Theoretical Physics Neil Turok, illustrates how our understanding of was developed and why there's nothing magic about it… except, perhaps, how they pack all that excellent info into 5 minutes. Enjoy!

Yes the numbers tell us is going to happen in a field but not what a field is or why it effects matter or other fields at a distance. So many questions remain for example why a magnetic field has little effect on gravity or how an anti-gravity field might be generated or why an electron that is stationary will not produce a magnetic field.

Modern QM is based on the idea that the original fields are based on the statistical distribution of the quantized force carriers for that field within the vacuum.

Electromagnetic fields have photons as force carriers, Gravitationsl fields have Gravitons, Color fields have Gluons, etc.

If the statistical distribution for the force carriers is not uniform then a "charged" particle that couples to the field will experience a force in a direction toward or away from the gradient in the charge carrier distribution.

On very small scales this force is caused by the absorption or emission of a force carrier from the "charged" particle.

Fields then are abstract "bulk" characteristics of space, and are the result of the virtual quantized charge carriers that constitute of fill the vacuum.

Short answer: it's that way and we don't know any simpler answer. "Why" questions can go on ad infinitum. There may be a more basic explanation, or it may just be that way because that's the way it is.

Indeed, it is interesting to note that conventionally physicists still do not understand what is magnetic field is, or how radio communication in mobile (cell) phone works. Even more they do not believe in Maxwell idea about his electromagnetic field, but instead, still using his equations to do their work! May be this physical view could help to visualize the matter.

All that stuff is just powered by Jesus, anyway. He's like, magic or something.
