An astrobiologist knows how to create a Dyson Sphere

Among the worrying – but predictable – news for mankind is the fact that they will soon face a lack of energy. This is not a new phenomenon: as early as 1960, Anglo-American theorist Freeman Dyson became concerned about it and sought a solution to the problem.

The physicist once imagined a kind of megastructure, the “Dyson sphere”: built around a star, it would make it possible to harness its energy. But the scientist left no clues needed to achieve what he described “A habitable shell”.

From then until now, Freeman Dyson’s theory has never ceased to attract the most ambitious scientists. According to Popular mechanic, German astrobiologist Dirk Schulze Makuch could be very close to a possible conception of the famous sphere.

Think of all the energy of our day that is available and available to humans. Undoubtedly: by moving us to stage II of the Kardachev scale, it will be possible to respond to the energy crisis in the very long term and even to dream even bigger. Why not, for example, use this energy to push us towards exoplanets, and be able to find other forms of extraterrestrial life?

A host of flying objects

Dirk Schulze Makuch is a professor at the Technical University of Berlin. Fascinated by speculations of extraterrestrial life, he began to take an interest in the Dyson sphere about ten years ago.

Together with Brooks Harrop, one of his former students, he was aware of many problems with his commonly accepted design. The most important of these is: the risk of the ball collapsing under the large weight of gravity, because there is no material available today that can withstand such a force. Engineers imagining a resistant structure have shown that it will use too much, if not all, of the energy of the central star.

If we can solve the first hurdle, the question of asteroids and solar flares remains that the structure must also resist.

Dyson himself found a possible solution: an unstable structure in the form of a host of flying objects, placed in independent orbits around the star. It will then amount to 10 million.

So Dirk Schulze Makuch and his student created a design to address these challenges, which they named the “Solar Wind Power Satellite” (SWPS). Their idea: satellites use not the energy of visible light, but electrons, which make up half of the solar wind.

These satellites, with a weight of approximately 3.7 tons each, can each meet the needs of the equivalent of 1,000 American homes. It can be constructed using relatively inexpensive materials, such as copper wire.

On the other hand, although they require little maintenance, these satellites cannot clean themselves and risk being damaged over time. Another hurdle also remains the organization needed for the deployment of several million – or even billions – of satellites in orbit.

If these challenges have not yet found sufficient answers, the hypothesis presented by Dirk Schulze Makuch is that other forms of modified extraterrestrial life may already be able to achieve them.

According to the physicist, if a life form is found on a habitable planet, it will eventually develop and become intelligent, the basis of this argument is that major evolution on Earth seems to have occurred many times independently. to each other.

According to Dyson himself, if an extraterrestrial life form realized a Dyson Sphere, we could know its existence. Perhaps the inhabitants of other planets have come to the same conclusion as the researcher, which is why perhaps this is not the most practical invention to effectively respond to the energy crisis?
