What is the most interesting thing you know?
Now that you are atheist or have been atheist your whole life. What is the most interesting thing you know about in our natural world?
I will chime in when this post gets rolling.

Now wait a second. If you're working in paint, try making yellow with red, blue, and green, which are the colors you need when working with colored light. They are two different systems, one additive and the other subtractive, but they are both systems based on primary colors. You make it sound like one of them is wrong.

Yup. It all depends on if you're working with light or with pigment. Erin needs to do more homework.

Actually, RGB is just what is used in monitors and artificial lighting because yellow is difficult to reproduce as a light source. In reality, there are no "primary" colors in light. It is a linear spectrum. Human beings perceive colors in light as the three primary colors because the photoreceptor cells in our eyes can only single out three very specific frequencies of light. So we see all light as varying concentrations of those three. Other species with different eyes key in to different frequencies in the spectrum and have an entirely different set of "primary" colors of light.

They are "primary" for visual artists (as distinguished from scientists), though, because any color the artist needs can be made by mixing them.

The cone cell types in our eyes are each most strongly stimulated by narrow ranges of light wavelengths; however, all three types are stimulated by much broader ranges than those peak wavelengths.

Actually red blue and green are the primary colours when using light, for example TV / Monitors.... these are actually called 'Additive Primaries'. Red, Blue and Yellow ARE the primary colours for pigments such as paint, dye etc etc.

The most interesting thing I discovered was that there were millions of people, many of them famous, that also felt others around them are delusional. I always thought there was something wrong with me.
That discovery itself helped my mental state in more ways than I can count.

An individual blood cell takes about 60 seconds to make a complete circuit of the body. Still blows my mind to this day.

The Universe. It popped into existence from an unimaginably small singularity and became billions (and possibly trillions) of stars.
Space. It was once thought to be filled with a substance called "ether" which allowed for the propogation of waves, because waves need a medium. Then the concept of ether was abandoned and space was conceived as emptiness. Today, physicists think of space as a substance in and of itself. A kind of foam. Mass distorts space, but if space were truly nothingness, what would be distorted?

Actually anything with mass distorts space. Do you mean folding space, as in the Dune series of books?
