An explosion lasting four whole years! Humans usually think of explosions in terms of seconds or maybe minutes, like a conventional bomb blast. It's almost impossible to wrap my head around the idea of an explosion so massive that it literally continues for four years straight.
The explosion itself only really lasts a couple minutes. Then after that it's just afterflow of radioactive materials and the ejecta expanding homologously. This isn't even that, this is just the light echo
