Q. The term ‘Gray goo’, sometimes seen in the news, is related to
Explanation:
Gray goo represents an apocalyptic catastrophe that involves the uncontrolled self-replication of nanotechnology, destroying all other life.
Gray goo is the term used by scientists to refer to a hypothetical condition of planet Earth where self-replicating nanobots have taken complete control of the planet by using up the energy of all life forms in it.
The term was first used in the book "Engines of Creation" by K. Eric Drexler.
Though the possibility of grey goo becoming a reality is extremely low, some scientists have raised concern over the energy needs of a possible nano invention that could replicate at the molecular level.
