Really odd question for you guys but I'm curious about your input, and apologies if it's a foolish question to ask anyway(I'm a CS student and this came up in a discussion with a classmate of mine). So I know this is a fairly odd thought and not likely practical in any real world scenario, but I was curious what input you guys might have(other than it being horribly inefficient The use of fiber optic cables has been used more often lately in enterprise deployments to make transferring large amounts of data faster. This got me thinking about the use of different mediums for transferring data. Ultimately here's my scenario: The speed of light is 188~k miles per second, this makes fiber optic cabling preferable to copper/electricity(Only in terms of speed/performance). If one were to take a 100 mile stretch of land(assuming flatland) and ran a fiber optic cable across it, and then a solid steel beam(theoretical scenario, 100 mile steel beam wouldn't be practical anywhere else obviously). If a machine were pushing and pulling(representing 1s and 0s), what would be faster for data transfer(aside from the obvious momentum and force needed to push and pull this massive beam). I understand this isn't exactly an electrical question, but I didn't think any of the other forums would've dealt with scenarios like this. Perhaps the material's flex/bend/impurities would account for some minor distortion in what would receive the signal, but I would assume a physical object being moved in realtime would be faster than photons being shot through fiber cabling, but I might be wrong.
