Quizplus · Accepted Answer

The background radiation in space is known as the cosmic microwave background radiation, which corresponds to blackbody radiation of approximately 2.7 K. This means that if you were to measure the temperature of this radiation, it would be around -270°C or -454°F. This radiation is the remnant of the Big Bang, and its discovery has been influential in establishing the Big Bang theory as the most widely accepted explanation for the origins of the universe.
