But those are fictional phenomena. A Super Nova is a known quantity.
So why can't the Hobus phenomenon be another fictional phenomenon that acts like a supernova in some respects
but turns out not to be like all other supernovae?
I'm not seeing the problem here.
Did you really need a line in the film that says, "Captain, it acts like a supernova in some respects
but it is not a true supernova"?
