SHORT TAKES:

I figured out the secret of everything while sitting in my room in 1990.
Actually, I did that many times, but this was one of those times.
It was incredibly simple: a piece of paper with six intersecting lines would form a grid with four cells. These cells can be either white or black.
Through what was for me highly advanced mathematics, I calculated there were two to the fourth power possible combinations of white and/or black grids, or 16 different grids patterns.
Now imagine a grid with ten cells to a side.
All the possibilities of dark and/or white grids laid out on a flat plane would already cover the solar system. It's an exponential increase.
The possibilities explode right from the start, and they only speed up forever, faster and faster, beyond all mental limits.
Reality will always be bigger than we think.

In the novel Infinite Thunder, I described the rod test.
Imagine a 20 billion light-year long rod, that exists outside the laws of physics. It has no mass, and can move at any speed.
If you sweep this thing across the sky, how long until it stops because some part of the rod hits something too heavy for your hand to push aside? Like for example a star, or more likely a tiny asteroid.
Well that's easy to estimate.
If you line up all the sextillions of stars, they would stretch clear across the universe. Even more so for the planets and all the smaller spacerocks.
So every time you sweep the rod around the sky, you're likely to hit many things, though most are so small you could push them aside (if you ignore the tremendous speed differences of hundreds of kilometers per second).

I believe teachers should teach by oversimplifying things.
Deliberately teach wrong even. But in the "right" direction, to compensate for biases.
I'm not a crank by the way. Cranks might disapprove of my writings almost as much as normies.
As a cranks crank, I criticized the Sokal Hoax.
Not because they were wrong about what they claimed to expose, but because the reaction they elicited (and what that reaction reveals about the baseline reality "consensus", the way "things are done") discourages free debate.
Complaining about that was one of the things that got me wrongly banned from LessWrong . . .
