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.
The coldest temperature in space is about 3Â°K above absolute zero. This is defined as the Cosmic Background (or Microwave Background) Radiation that was first detected by Penzias and Wilson using the Holmdel Horn Antenna in New Jersey, USA in 1965.
