OK, this is getting out of hand now.

Last November, 14-year-old Lucas Etter set the Guinness World Record for becoming the first person to ever break the five-second barrier, solving the Rubik's Cube in a mind-boggling 4.904 seconds — only to be outdone by a robot using a special algorithm to solve the Rubik's Cube in 0.9 seconds two months later.

Now, the World Record has been unofficially rewritten once again. That's because Gizmodo spotted another robot solving the Rubik's Cube even faster.

Adam Beer's Sub1 robot solved the cube in only 0.887 seconds, defeating the recently-set machine mark of Jay Flatland and Paul Rose's robot, which used a combination of 3D-printed parts, motors, an Arduino chip, webcams hooked up to a Linux system and what's called a Kociemba algorithm to previously set the bar at the 0.9-second time last month.

The Sub1 cut under that time and used just 20 moves to make it happen, powered by a computer algorithm of its own. Watch in awe below.

Although the blazing-fast feat could be seen on Sub's YouTube account, no Guinness officials were present like they were for Flatland and Rose's robot, so Beer's machine will still need to be verified to claim the new World Record.

Also, Etter can breathe a sigh of relief in knowing that Guinness distinguishes between humans and machines for its records, so his mark still remains tops as far as us simple humans go.
