Undergrad Is the existence of a Dyson Sphere impossible?

Click For Summary
A monolithic Dyson Sphere is deemed impossible with current materials due to structural limitations, but theoretical concepts like a Dyson Balloon could work by utilizing solar radiation pressure. This balloon would require active control to maintain its position around a star, effectively making it a leaky Dyson Sphere. A Dyson Swarm, composed of multiple smaller structures, may be a more feasible option for harnessing stellar energy. Such designs could potentially maximize energy capture while reducing detectability to other civilizations. Overall, while a monolithic Dyson Sphere is impractical, alternative concepts offer intriguing possibilities for energy collection.

Specifically a monolithic Dyson Sphere; also, how would a Dyson Swarm work / be a better option?

Not specifically, no.

Better option for what?

Is this a science fiction question?

A monolithic Dyson sphere without moving parts wouldn't be possible with materials we know, but in principle you can stabilize it with fast-moving (faster than orbital velocity) components.
 
Perhaps one could make a Dyson Balloon inflated by solar radiation pressure around a star but there would have to be some sort of active control to keep the balloon centered around the star by manipulating the surface transmission/reflection coefficients to compensate for drift so it would amount to a leaky Dyson sphere. Of course one could not build structures on such a surface but it might go a long way towards Dyson's goal of using all (or most) of the star's energy and making the star less detectable to outside civilizations.

Thread 'Lunar Orbit Issues & Lunar Clocks'

I recently purchased a lunar clock intended as a Christmas present for a young family friend who has become interested in astronomy. The clock face shows twelve images of the Moon in all its main phases, with the Full Moon depicted at the "twelve o'clock" position. Now I purchased this clock especially early to allow time to check on its accuracy. After waiting for a full lunar orbit to occur, I have since discovered that the clock time when measured relative to its lunar images (that's to...
