Science & Technology Current Affairs Analysis
Context:
The Dyson sphere is named after theoretical physicist Freeman Dyson (1923-2020), who hypothesised its existence. He said that technologically advanced civilisations will have such a tremendous demand for energy that they will have to harness the entire radiative power of a star, using solar energy collectors arranged in a sphere around the orb.
Dyson also figured that these spheres would emit excess heat from the star as infrared radiation
Recent development:
In May this year, scientists set out to look specifically for the signature of Dyson spheres.
They scanned 5 million stars within 1,000 light years of the earth. After analysing this data, they found seven stars whose infrared radiation they could not explain. There is no conclusive evidence still
