Several decades ago, I decided to see what the background might look like if the universe is infinite. As light travels, there are a few obstacles: 1) Dust, thought to be minor, on the grand scale it will creating a peak in the infrared. 2) Lyman absorption lines due to neutral cold H2 and 3)...

Yes, that is a better analog because a hydraulic motor or water wheel does work. The valve analogy works if you are fighting a fire: The height of the column of water is closely related to the pressure (voltage) and the volume (current) of water that you can push though the nozzle is dependent...

Ohm's Law is like the perfect gas laws, it is idealistic, and it does not 'translate' well to gravity and inclines. A much better analogy is water pressure and current. Current is the pipe diameter, pressure is the voltage, and resistance is the function of a valve in the pipe, The amount of...

All radiant energy obeys Chandrasekar's equation for radiation transfer. Gases in space are often ionized because of interactions with high energy photons, and there is a net radiation background that we are all aware of. "I guess what I'm asking is; is it difficult to directly see how many...

A steel pipe will conduct a local field via eddy currents. The conduction will be week, but at the right frequency, and with a differential detector, in most cases it is possible to detect a coil inside a steel barrier at very short distances. Your source current must be very close to the...
