What is a very direct, though less frequently used, substitute for the term supernova?
Answer
stellar explosion
A very direct substitute mentioned for the term supernova, although less frequently utilized in specialized contexts, is 'stellar explosion'. This phrase adequately conveys the fundamental action involved—the sudden, energetic release of energy associated with a star ending its life cycle. However, it is noted that this term lacks the inherent scientific specificity carried by 'supernova,' as 'explosion' could potentially describe other, less catastrophic stellar flares.
