What is the hardest thing for you to wrap your brain around

Maybe the sheer size of the universe? The speed at which light travels? The size of a quark?

Out of all the things in the universe, what is hardest for you to possibly imagine, as long as it's generally accepted it doesn't have to be proven.

For me it's both the size of the universe and the size of a quark. I mean, sitting here trying to wrap my head around how something can be so unbelievably large, yet also thinking how something can be so unbelievably tiny.

Kind of ironic a little bit, how something like a solar system is similar to an atom even though their sizes vary beyond belief.

I used to have a problem with infinity. I kept using it like it was a number.
For example, I couldn't understand that the amount of numbers between both 0 and 1 and 0 and 2 were both the same.

I haven't quite wrapped my brain around it yet.

The structure of the human eye and how the process of vision functions, and then dreams.

What is the hardest thing for me to wrap my brain around? Has to have to been a tarmac road surface ... well, I suppose wrapping my skull around the road and my brain around the inside of my skull is technically more accurate.

Other than that it is probably why anything exists at all (and, please, do not try and expound some hypothesis involving quantum theory and zero point energy fluctuations ... such hypotheses presuppose the existence of a quantum field and so on)

The Riemann Hypothesis. I don't understand it.

But I'm not even very good at differential equations.

Why diamonds?

Aren't some infinities larger than other infinities?

In a way, yes, that's what Cantor demonstrated in the late 1800s.

If you took the number of numbers in between 0-1 and divided it by the number of numbers between 0-2, you should get 1/2.

Let x be the number of numbers between 0-1. There are an equal number of numbers between 0-1 and between 1-2, so the number of numbers between 0-2 is x + x, or 2x. So you have x/2x, and even if x is infinity, they cancel (they're the same infinity).

I'm sure mathematicians will murder me for doing it that way, since I probably did all kinds of things wrong, but I think that's the general idea.

Hard to say.

Jimmy Snyder likes to joke a lot. Diamonds are extremely hard. His post above mine is also a pun.

How and if an inverse tangent function "jumps" from positive infinity to negative infinity.
