When I push on my eyes in the dark and "see" patterns or colours, there's no em energy entering my eyes. My eyes are closed at the time. And yet I still see something. My neurons for sight are still firing. So, is there "light" involved in this, or not? According to what you said early, there is. Where is the light? Or do you want to change to a different definition of "light" now?Both, a brain phenomenon by use of the em energy, a conversion of energy into an electrical chemical signal.
A prism refracts different frequencies of light at different angles. This is due to the fact that light of different frequencies travels at slightly different speeds in glass. This is called dispersion.Paddy how does a prism untangle the entangled mixture of frequencies of white light?
If you place something (e.g. a sheet of paper) between your eyes and the computer screen, then you can no longer see the screen. That suggests that the sheet of paper is stopping something from the screen from reaching your eyes. What could it be stopping?Look at your computer screen , notice the rgb white background and observe the space between your eyes and the white it is clear.
Let's try to cut to the chase.The truth at last clear not white, ok so what value is this clear compared to sight?
No, the "top squiggle line" is EM radiation, including light. Rayleigh scattering is why the sky is blue.Your top squiggle line is why the sky is blue.
You say clear... do you mean white light? White light is not "clear"...
Constant of what? Do you even know what a constant is?
... No... no it isn't. If it were "a brain thing", then machinery wouldn't be able to detect it... and we have plenty of photosensitive equipment that can...
I know the ''squiggle'' is em energy/radiation, when new arrives, other things fall into place. The sky is said to be blue by the Rayleigh scattering, but my idea says it is blue by bottle necking.No, the "top squiggle line" is EM radiation, including light. Rayleigh scattering is why the sky is blue.

Or, maybe putting the sheet there stops something from your eyes reaching the screen. What could it be stopping?
Did anything change about your eyes when you turned the screen off?
Did anything about the screen change when you turned the screen off?
It's a mystery, isn't it? Whatever could have happened that meant you could no longer see the screen?
Got any ideas?
Let's try to cut to the chase.
"Clear" just means "transparent", which means that light can pass through unimpeded. "Clear" is a property of a material. Air is "clear". The opposite of "clear" is "opaque".
"Light", on the other hand, is the opposite of "dark".
"Light" and "Clear" are not the same thing. Neither are "dark" and "opaque".

Now, turn off your screen and turn off the lights in the room. Shut the blinds. Now you can't see the screen, even though there's nothing in between it and your eyes. So what happened? Did the "clear" go away? What changed about that space between the screen and your eyes? Something? Nothing?

I have time on the internet, I do not need a course to show science a Paradox from discourse of information I do know.I think your difficulties might be cleared up not, as several have suggested, by taking some elementary courses in physics, but by taking such courses in semantics.

My eyes are never closed to knowledge, it is your knowledge that lead me to my ideas.Your eyes are closed and so the light of knowledge is unavailable to you.
yes that sounds about correct.@ theorist-constant
Is this you'r idea.???
Ther was em energy before ther was eyes... but wit-out eyes ther was no "light"... simply because ther was no eyes to transform the em energy to what creatures wit eyes percieve as light... ie... before eyes ther was only darkness.!!!
Now you understand it , hopefully you can now visualise it and see the nature of ''light''. If you can explain it any better than myself please do so. It took me several years to be sure of present information and details, I draw the same conclusion every time.@ theorist-constant

I am defining evolution and seeing in the dark which you have just admitted to by your post.Well caught clueless husband!
tc12345, you do need that class on semantics. You are defining light as the perception of em waves: correct? If so you are not saying anything new. Or especially interesting.
