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.
Interstellar space is very cold. The density of interstellar matter is extremely low. It averages roughly 10 6 atoms per cubic meter--just 1 atom per cubic centimeter--but densities as great as 10 9 atoms/m 3 (1000 atoms/cm 3) and as small as 10 4 atoms/m 3 have been found.
