I'm having trouble doing some numerical estimates for calculating the Dyson Sphere that was found in ST:TNG S6e04 - "Relics"! It was stated on screen to have a diameter of 200 million Kilometers while the Enterprise was outside scanning the surface. It's stated on screen that it has an internal surface area of approximately 250 million M-class planets. http://memory-alpha.wikia.com/wiki/Dyson_sphere https://vignette.wikia.nocookie.net...ision/latest?cb=20170314135313&path-prefix=en https://vignette.wikia.nocookie.net...ision/latest?cb=20140403132538&path-prefix=en Given the info that we have, how thick do you think the shell is from the picture that I linked? What is the Diameter of the largest circle on the exterior entry hatch?
