Hey YouTube what's up?
My Name is Kenneth.
Today I want to share with you some thoughts I had on the Rubik's Cube and what makes
it so hard to solve.
Now this is a new kind of video for me, so please let me know what you think in the comments
bellow. If you like it, hit the thumbs up or share it with a friend.
Have you ever wondered why a Rubik's Cube is so hard to solve?
The reason the Rubik's Cube is so hard to solve is because a Rubik's Cube can be twisted
into many different positions, yet there is only one position that is solved.
So how many positions can one twist a Rubik's cube?
It turns out the answer is 43 quintillion.
43 quintillion sounds big, but how big is it.
Well here's one way we can think about it.
Let's imagine I wanted to see every position of a Rubik's Cube. So what I did was I drew
each position on a separate piece of paper. Then I stacked all 43 quintillion papers.
Let's see how high the stack would be.
So I started on the kitchen table. It didn't take long before I needed a ladder. Soon the
house wasn't big enough. I had to take it outside.
The latter wouldn't take me high enough so I found a crane. Pretty soon even that
wasn't high enough.
With the help of a hot air balloon I continued to stack. Now my stack was higher than the
tallest building in the world.
I really began to enjoy this project. Soon it took me where no one else had ever been.
Now I was farther than the moon.
I really got to know our solar system. Here's the Sun, Mercury, Venus, Earth, Mars, the
Asteroid Belt, Jupiter, Saturn, Uranus, Neptune, and Pluto.
Pluto's no longer a planet, but let's just assume I didn't get the memo.
I continued the stack and took myself on a grand tour of our solar system. I went straight
toward Pluto. Once at Pluto I realized I was low on fuel and food and should probably start
heading back. So I started a stack on Pluto back toward Earth.
The trip back seemed to go by quickly and eventually I returned to earth. It was depressing
to know I wasn't even half way done. After fuelling up the tank, It was time for another
trip. Resolved to finish this epic quest I set out on multiple trips.
I finally finished all 43 quintillion positions. It only took 728 stacks.
Hidden out in the mass of papers is one paper that is special. Each paper has a unique picture
of a Rubik's Cube, but only one paper has the picture of a solved Rubik's Cube.
It's your job to find that paper.
Good luck!
