If I go onto a lift , I have repetitive thoughts. I think to myself that the lights in the lift use more power than the lift itself. This is because the motor doesn't lift the box directly, it uses pulleys and a counter weight. I imagined being able to stop the lift motor with my hands because it spins very fast but with low torque pressure. The pulley system converts the turn speed into a slow rotation with high pressure just like the first gear in a car. When your car is in first gear the turning speed is converted to torque pressure so the wheels turn slowly but with more force than the engine itself. I don't know if I can stop a lift motor with my hands though, I only know they turn with less force than the last pulley in the transmission.
Then as the doors close I wonder if the world behind the doors exists. If we're living in a simulation then things that I can't see would disappear. If there is a glitch in the simulation, the doors could open and there is nothing there, just darkness. Then I think to myself that the simulation thought is silly and I just think about what is relevant to that time.
