Researchers believe that looking for techno-signatures, such as structures for generating huge amounts of energy, is not a good way to detect aliens.

Scientists have several ways in which they continue to search for extraterrestrial advanced civilizations in our galaxy. One way is to look for evidence of the existence of advanced technologies. One popular idea is to look for signs of Dyson spheres around stars or arrays of solar panels covering other planets.

But the authors of a new study published in The Astrophysical Journal believe that this is not the best way to search for aliens.

Most likely, aliens will use the energy of thermonuclear fusion or invent other more efficient ways to obtain energy than collecting starlight.

Based on this, the authors suggest that an alien civilization can survive and achieve a high level of development using only a portion of the total amount of energy that their home star produces.
