This was inspired by Daniel de Bruin's "universe's biggest gear reduction":
• The universe's biggest gear reduction...
The finished gear ratio:
10341796308487334800992832804222885104773611498499997696000000000000000000000000000000000000000000000:1
or 1.0342e100:1
or 1.034 GOOGOL:1
Rotation time for the last gear:
52433879932503535381614991275498187972589101825233846406570841889117043121149897330595482546 years
or 5.2434e91 years
Formula for the gear ratio:
24/8 * 40/8 * 40/8 * 40/8 * 60/1 * 12/1 * 168/1 * (140 / 8 + 1) * 141 * 20/12 * (40/8)^20 * 20/12 * (24/1)^20 * 56/16 * (36/1)^10 * (40/1)^18 * 15/9 * 56/1
List of gears used:
27x Gear 8 Tooth [3647]
1x Gear Expert Builder 9 Tooth [g9]
6x Gear 12 Tooth Bevel [6589]
2x Gear 12 Tooth Double Bevel [32270]

2x Gear 20 Tooth Bevel [32198]
23x Gear 24 Tooth [3648]
10x Gear 36 Tooth Double Bevel [32498]
49x Gear 40 Tooth [3649]
2x Turntable Large Type 2 [48452cx1]
1x Turntable Large Type 3 [18939 / 18938]
8x Gear Rack 11 x 11 Curved [24121]
1x Gear, Hailfire Droid Wheel [x784]
1x Gear Worm Screw, Short [27938]
51x Gear Worm Screw, Long [4716]
For those wondering, the visual effect I used in the end montage is called Find Edges, comes with Adobe Premiere 14.

I need this to turn my shower handle just enough so It doesn’t burn or freeze me
-
See y'all in 5.2×10⁹¹ when this gets recommend again
-
Imagine how fast the initial gear would spin if the angel was manualy turned
-
This is like some ancient, epic machination that Leonardo da Vinci would conceptualize/build, but never live to see it do the thing.
-
This quickly went from “I see what you did there” to “what the hell is happening.”
-
“I will rotate once per universe”
-
Everyone's talking about how long this clock takes to turn but no one is talking about what a legend this dude is for willingly putting his thumbs through that for us. I'm filled with awe!
-
Sobering thought - it would take approximately 4.092 x 10^89 years just to take up all the gear slack in the system.

>turns the opposite end >first gear flies off at light speed >knocks the moon out of orbit

"Give me a gearbox large enough and I shall spin the Earth" - Archimedes, probably
-
What fascinates me most about this kind of thing is how something perfectly calculated, where you know exactly how it's going to move, will never be seen in practice. Think about the resulting torque, what something like that could move, or if the system were unbreakable, and an infinite force could make the last piece turn, how insanely fast the first gear would turn. Just as we know the laws of physics, perhaps we could witness events that rip it apart if they happened. Really powerful video, thank you.

This should be placed in a museum, put on a permanent power source, and left alone forever.

Gear 51 slips* “This little maneuver’s gonna cost us 51 years.
-
The most disturbing part about this is that the final gear is still moving but like, it’s just
-
The torque on that last gear could lift a planet. Assuming you made the gears out of some exotic materials
-
At this point he's just flexing with all those Lego gears he's got
-
Feels like the Lego man sitting there is experiencing some mythological torture. He will be free after he has rotated once, and has to watch the quickly rotating gears in front of him while the ones behind him are barely moving at all.
-
I was way too baked for how this ended
-
If you were to attach a very very very very very very long ruler to the Angel, how long would the ruler have to be to see movement at the end of it? Say snail’s pace?
