Watch as a Computer Solves a 32,768x32,768 Rubik's Cube in 2,706 Hours
3-D colorful combination puzzles, in other words: Rubik's Cubes, have been around since 1974. Created by Hungarian sculptor and professor, Ernõ Rubik, we've mostly known them as hand-sized squares with six different colored little cubes to each side.
With technological advancements, the cube has also moved forward with time. This video by YouTuber ShellPuppy does just that. Impressively showcasing a computer solving a 32,768 by 32,768 cube - just shy of the equivalent of the Burj Khalifa's height (that's 2,722 feet tall) - in 2,706 hours.
Initially, you start by seeing just how big the Rubik's Cube is, starting off with its regular shape and size, then noticeably increasing to a T-Rex dinosaur's size, then able to carry the weight of an airplane, being as tall as the Eiffel Tower, and finally reaching its final height and dimensions. Unfathomable yet entertaining.
It took the computer eight billion moves to solve it.
Luckily, we don't have to sit around and observe the computer for over 2,000 hours! This much shorter 15-minute long video gives us the highlights of the computer's moves.
