This is wrong: I know there are things that exist I dont know. What really is going on is this: I don't know what the things I don't know are.
Example:
One of the things I didn't know existed was red food dye with the name Carmine also known as Crimson Lake, Cochineal, Natural Red 4, C.I. 75470, or E120 -
(I knew something was the reason for red dye but I never knew what it was I didn't know Carmine existed)
It is made by killing insects in hot water (after which they are dried) or by exposure to sunlight, steam, or the heat of an oven. Each method produces a different color, 
You need to kill 70000 cochineals for 1 pound of color.
Now that I know I don't eat alot of stuff that is dyed with this crap.

So now that I know red dye is made by doing something like this. My horzion broadened I now know there is other stuff out there I have no idea about. Because I found out therre is at least 1 thing (carmine) I had no idea about at all. Now I know there is a process to create blue dye/green dye etc. but I don't know what the process looks like. This is something I know it exists but I dont know how it works.
I know there is a possibillity of life on mars but I am not sure if it really exists or not. This is something I know that might exist because people mentioned it before
Then there is things I or no other human for that matter even thought about. Like no person in 1492 was thinking about mobile phones. Or a neanderthal pretty much had no idea that deep in the sea there is something called lantern fish. This is why I know there is something I never heard of that exists but before I find out what it is I have no idea what it is.
