Is there a limit as to how big a person can build a telescope?
Interesting question actually. Depends on how you are defining the term “telescope.” Your details are confusing though, unless by “more of space” you mean increasing the sharpness of the image, which is normally the goal of “bigger” telescopes. In any event I am assuming you are talking about optical telescopes, IE seeing visible light In terms of a single refracting lens, the limit has prolly already been reached. At some point the lens is so heavy that just moving it around makes it flex and thus ruins the image. Plus it’s hard to control the temperature of a huge heavy piece of basically glass, again causing distortion in the image. This is why astronomers switched to reflecting telescopes decades ago, then all you need to control is the surface of a mirror, an easier engineering problem. Again though there will be an upward limit, since you still need to keep the surface and shape of those mirrors perfectly constant. I wouldn’t want to even guess what those limits are. For all prac
