Belligerent refers to a tendency to hostile behavior: A belligerent reporter badgered the politician. Bellicose describes a warlike or hostile manner or temperament: Madison, far from being pushed into war by a bellicose Congress, had to drag his own hesitant party into it. (Garry Wills).
How cold is it in space? That question is sure to prompt the geeks among us to pipe up with â2.7Kâ. For 2.7 Kelvin, or 2.7 degrees above absolute zero, is the temperature produced by the uniform background radiation or âafterglowâ from the Big Bang. But hang on.
And they come to mind, pretty much, as soon as you leave the Earth. Well, the temperature of space is, at its coldest, just the temperature of the leftover glow from the Big Bang. This radiation, known as the Cosmic Microwave Background, bathes the entire Universe in a temperature of only 2.7 Kelvin.
