GARDEN OF PHYSICS: Dayson sphere

GARDEN OF PHYSICS: Episode 14
Dayson sphere
Guest: dr Marko Vojinović

’Dayson sphere is a hypothetical structure which encompasses a star’, says Dr Marko Vojinović of the Institute of Physics, Belgrade in the fourteenth instalment of popular science video series ’The Garden of Physics’, describing the concept of the recently deceased renowned theoretician, mathematician, physicist and statistician  Freeman Dayson.

’The concept is that there exists a swarm of asteroids and similar objects which would completely enclose the light of a star. It would harness all energy radiating from the star while, from the ground, we would see this structure as a star emanating exclusively infrared radiation’, elaborates Dr Vojinović noting that it is a way to detect developed extra-terrestrial civilizations.

The series ’The Garden of Physics’ was launched by the Institute of Physics, Belgrade inspired by the concept of popular IPB forums, which until the epidemic gathered large audience at the Big Hall of the Students’ Cultural Centre. Realized in cooperation with the portal ’Science Through Stories’, each episode of  ’The Garden of Physics’ is dedicated to one of the fundamental topics of modern science. However, instead of doing it in front of an audience, we now talk with physicists and other researchers in the garden of the Institute, on the banks of the Danube in Zemun. 

Realized in cooperation with the portal ’Science Through Stories’, each episode of ’The Garden of Physics’ is dedicated to one of the fundamental topics of modern science, whether it is the greatest secrets of our times or research indicating unexpected horizons in the perception of the world. New episodes are aired every Friday online and they are available on webpages of the Institute of Physics, Belgrade and the portal „Science Through Stories“, as well as on You are welcome to join us.
