Dyson Spheres : Study
Dyson spheres are hypothetical megastructures built around a star to harness its entire energy output.
- Named after physicist Freeman Dyson, these structures would collect all of a star’s radiant energy.
- Detecting a Dyson sphere could indicate a technologically advanced alien civilization that prefers not to communicate.
- Earth receives 1,361 watts per square meter from the sun, a tiny fraction of the sun’s total energy output of 380 billion quadrillion watts per second.
- A Dyson sphere would capture all this energy that otherwise radiates into space.
- The Kardashev Scale is a theoretical framework to measure a civilization’s level of technological advancement based on its energy consumption.
- Humanity is currently at Kardashev Type 0.7449, not fully utilising the energy available on Earth.
