Scientists Challenge Freeman Dyson’s Ideas on Megastrusts around Stars
A new study titled “Search for planets, engineering moved into the zone of their stars” offers an alternative perspective on Freeman Dyson’s proposal about the creation of megastrusts around stars. The research, led by Narasimhi, questions Dyson’s notion of constructing artificial biospheres around stars to maximize space and energy potential. The study is available for reference here.
In 1960, Freeman Dyson put forward the idea that advanced civilizations could construct artificial biospheres surrounding stars. However, the team of researchers, headed by Narasimhi, challenges this concept based on current knowledge about planetary bodies.
The researchers argue that Dyson’s proposal, which involves utilizing the resources of a planet like Jupiter to create a megastrust, fails to consider that only a portion of Jupiter’s mass would be suitable for such construction. Narasimha and colleagues also highlight the potential risks associated with maintaining an ecosystem and protecting against cosmic radiation within such a structure.
Instead, the researchers present an alternate approach – relocating the planets into the habitable zone of their respective stars. “If the planets demonstrate unconventional characteristics, such as alternating masses, it could indicate technological intervention,” explains the team.
In their study, the scientists make a case for the possibility of technologically advanced civilizations manipulating planets. They propose the existence of powerful laser masses, readily noticeable from distances spanning hundreds or even thousands of light years.
In conclusion, Narasimh and his colleagues call upon astronomers to focus on detecting unusual exoplanetary systems as potential indicators of extraterrestrial life and the activities of advanced civilizations.
