An astronomer has suggested that intelligent aliens may be hiding in the “Tyson Mantle” orbiting white dwarf stars across the Milky Way.
Tyson Mantle is a theory developed by Freeman Tyson in the 1960s that seeks to explain how alien civilizations meet their energy needs when they exceed the limits they can only create from their planet’s sources. Tyson believed that advanced alien life would orbit the star of its solar system completely, creating a large envelope that would capture much of its fiery energy.
Ben Zuckerman, a professor of physics and astronomy at the University of California, Los Angeles, has suggested that aliens may be found in these envelopes around stars.
Zuckermann did not think that extraterrestrial civilizations would bear the burden of traveling toward the new star to create Tyson balls. Instead, they will form these energy-absorbing balls around the star of their solar system, which will eventually turn into white dwarfs after filtering the fuel in it.
The White Dwarf is a small, dense star about the size of a planet.
In this way, Zuckermann hopes that by looking at the Tyson spheres, astronomers will be able to estimate how many advanced civilizations exist in the galaxy.
So far, only a small fraction of white dwarfs have been studied by astronomers, but scientists have not found any “Tyson shell” around them. Opponents of this theory, therefore, believe that the white dwarfs studied so far are, in fact, sufficient to find a “Tyson shell”.
