Some interstellar objects could originate from destroyed Dyson spheres
The constructions made by high-tech aliens to exploit the resources of the stars could end up destroyed and disappearing into the stellar void. Artist’s interpretation of what a Dyson sphere would look like. Credit: dottedhippo.com Statistically speaking, a human-sized rock impacts the Earth each year releasing amounts of energy similar to that released by the atomic bomb dropped on Hiroshima at the end of World War II. If it were electricity, this would equal the world’s average usage for 20 seconds; 15 kilotons of TNT. The potential of celestial objects near Earth is determined based on the space they travel. Because there is 60 times more distance between the Earth and the Moon, this means that similar pieces of rock pass within that same separation about 3,600 times more, the equivalent of 300 times per month. Furthermore, within the area bounded by its orbit around the Sun, millions of steps like that happen every year. On Janua...
