Can a civilisation with our current technology become a Kardashev-2 level society? (science video)
Kardashev-2 Civilisations are a hypothetical society that can encompass entire stars, tapping billions of times more energy than Earth currently uses (often by constructing megastructures like Dyson Spheres/Swarms).
But could a civilisation with Earth’s present technology level also become a Kardashev-2 if we really pushed the boat out?
Well, Isaac Arthur has the answer to that one, and it might just be – spoilers ahead – yes!
