["Because the physics of supernova explosions is extremely well-known " .... until the newest future discovery proves them all wrong.]


This is a common misunderstanding of how the process of science works to advance knowledge, and it's an error based on the assumption that an established theory which is refined in order to improve its compliance with observed phenomena must have been fundamentally wrong to begin with. An example of this is the established theory of Newtonian mechanics describing how objects move through space, modified by relativity theory so as to explain small anomalies of Newtonian theory observed under unusual conditions, such as near the speed of light. Newtonian theory is here being refined, not replaced, and few would criticize that the Newtonian laws of motion which millions of people find useful everyday, are now invalid.

Newtonian theory is replaced in your assessment.
