    Are you saying you move the first one and it takes years before the last one moves? Meanwhile all the ones in between are moving the whole time? That sounds impossible!

      It’s because of gear ratios. For each movement of the first gear , the second only moves a fraction of that, let’s say 1/20th. If the first gear moves at 1 full rotation a second, the next gear moves 1 rotation every 20 seconds, the next 1 every 400 seconds, and so forth. It adds up quite quickly, the tenth gear would take 16,235 years to make a full rotation in my example.

      The picture above may or may not need more time than could exist in the universe to see any moment in that last gear.

      No, you’d turn the first one then the second would only move a fraction of the amount, and the third would only move a fraction of that amount, and so on.
