They're all "touching" but only because they're literally inside each other.

I never thought of that. Since I watched the videos with Feynman talking about stuff, I understand that the electromagnetic force of the particles prevents a solid from going through another (or something like that), but until now I always assumed that the elementary particles were themselves solids. But now that I think about it, why would they be ? What if they were only entities, virtual concepts with mass, which makes them attract each other, resulting in the entire universe ? And now that I think about it, what is mass anyways ? How can something attract something else that is billions of kilometers away ?

I think my favorite feeling ever is realizing how little I know about the world I live in, and how I am even able to type this. Also, what of that ? What of the amazing level of complexity involved in me typing this for other people to read ? That means intelligent beings, that developed a complex way of communicating, translated it into something visual, then developed machines that uses electricity going through certain circuits and not others to achieve various goals, in which you enter your message through complex hand movements and a wonderful plastic device, for your message to be converted into electric impulses, which will then be sent through cables and radio waves, onto another machine, which will stock it and send it back to whomever wants it, to be then interpreted by yet another machine, reconverted into a message, then displayed through a device that I don't have a clue how it works, for the remote human to read and interpret as the idea I was originally trying to convey.

Okay, I think that's the definition of getting carried away. You got the point. The world is amazing and all the people who don't realize this really miss on something.
