The discussion centers on the potential for creating the strongest actuator by an infinitely advanced civilization, focusing on the ability to exert controlled force in both linear and rotational movements while ensuring non-lethality at close distances. Advanced optical tweezers are highlighted as a theoretical option that could surpass traditional mechanical actuators in strength. By manipulating materials at the molecular level using beams of different wavelengths, these tweezers could apply force across the entire volume of an actuator, allowing for greater accelerations and pressures than conventional methods. Current mechanical actuators can exert forces around 10 GN, comparable to diamond anvils, but are limited by speed and the risk of shattering. Theoretical advancements in optical positioning could enhance speed without significantly increasing force limits. The conversation also touches on the maximum physical limits of human-sized actuators, emphasizing the need to consider the fundamental laws of physics in these discussions.
