I 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 'Population 3 star (Pop III) candidate LAP1'

"Pop III stars are thought to be composed entirely of helium and hydrogen with trace amounts of lithium, the ingredients left over after the Big Bang. They formed early on, around 200 million years after the universe began. These stars are extremely rare because they died out long ago, although scientists have hoped that the faint light from these distant, ancient objects would be detectable. Previous Population III candidates have been ruled out because they didn't meet the three main...
