In a few different videos, Courtney explains the presence (or lack of presence) of Harvey and company. I understand some aspects but if possible I'd like more clarity about other aspects

Here's what I understand: For lack of better words, there are organisms and other devices that exist on a different "phase" of reality. In fact there's a whole other world (or several) that exist not quite tangible to us. We have technologies that we can develop or use to detect them, and also natural abilities to detect them (we call remote viewing) that the masses have yet to explore.

You could almost think of it as a ,4th spacial dimension. There's up-down, right-left, forward-back and phasein-phaseout. But we don't have to start getting that complicated.

Ok. We know that light sees different things depending on the frequency. The less dense the object, the easier it is for light to pass through. The more energized the light wave is, the more easily it can pass through denser objects. That's why our most powerful lights, gamma ray emitters (high frequency), pass through shipping containers to detect the contents inside. That's why infrared sensors (low frequency) pass through barely anything. A clear window can look like a black wall in an infrared ray detector.

Ok. So we know that powerful lights see through dense objects. But can you give me any common examples where an object refracts a certain wavelength of light, but matter can pass through it. Certain gases appear black to infrared, and we still "feel" the gas as a fluid dynamic. Is that a subtle example? Or are some objects dense in a way that it could refract gamma rays, but infrared passes through it?

Like are there examples that show not only higher density and lower density - but things that have greater density at a high "phase" like gamma rays, and simultaneously things that have a higher density at a lower "phase" like infrared?

Is that making sense? I really want yo get this a little better

Actually, I think a better way to pose my question coming up

You have 2 lightbulbs, 2 cameras, and 2 ornamental frogs.

A blue light, a blue camera, a blue frog, a red light, a red camera, and a red frog.

The red frog is like a clear glass with a reddish tinge. The blue frog has some blue paint and is made up of solid iron. The red light is actually an infrared emitter. The red camera is an infrared scanner. The blue light actually emits gamma rays, the blue camera detects gamna rays. When the blue light shines through the blue frog, the blue camera still sees the blue frog but it can see through solid parts like it's almost thin glass. The red light shines through the red frog. When the red camera sees the red frog, it shows a pretty dark solid object as if it were metal.

Now switch the frogs.

The red light shines on the blue frog, the red camera picks up the blue frog and sees nothing but this dark solid object. The blue light shines through the red frog and the blue camera doesn't really pick up anything, because the light shines through it like it's plain invisible.

Notice that the opposite does not happen. You can't come up with an object in which the red light passes through it, but the blue light does not pass through it.

Now for Harvey and company, we need an example where some sort of ornamental frog has the red light pass through it, picked up by the red camera, but the blue light does not pass through it, and is not picked up by the blue camera
