Is it possible to for the home experimenter make the 3 invisible fields for Gravity, Magnetism, and Voltage visible ???
If it was, then we could see these forces in action in real time, as experiments are conducted. This would allow us to see the results of tweaking various parameters of an experiment while it is running, and enabling further investigation, and tuning of the parameters of a device - like changing voltages or changing frequency, tuning LC circuits, re-arranging the layout configuration of a devices components, etc, etc.
One cannot see the fields in the layman sense.
However, one can observe the results produced by such fields. The problem is that one needs an in-depth understanding of the theory before one can correctly interpret the experimental results.
The debate at http://www.overunityresearch.com/index.php?topic=771.0 is interesting. It raised the bar of understanding. One cannot claim that something is right because he believes that it is logical. He must check to see if that something obeys the equations of Physics.
I look forward to the continuation of that debate to all the various force fields.
