If there are alien civilizations in the Universe, some of them could be super advanced. So advanced that they can rip apart planets and create vast shells surrounding a star to capture all its energy. These Dyson spheres should be detectable by modern telescopes. Occasionally astronomers find an object that resembles such an alien megastructure, but so far, they’ve all turned out to be natural objects. As best we can tell, there are no Dyson spheres out there.

A super advanced alien civilization, I think, would try to explore new planets rather than create a mega structure like Dyson spheres. The stars, even if their existence lasts billions of years... still, it has its finiteness, and its death is an immeasurable destruction all around

Exploring planets looking for possible energy resources comparing to stars which are a definition for energy generators is silly in my opinion

I was just rambling on the topic. I agree with you... it would be much more uncertain to explore resources on other planets than using the Dyson sphere.
