I think that each generation produces its own theories to explain known observations. Sometimes the theories are good working models, other times they are models made up to fit observations which can allow more work but are known or guessed to be a problem.
A good one which was later shown to be wrong and just within living memory ( I think) was the ether...an undetectable medium which allowed light to travel from place to place through a vacuum.
Another one is evolutionary contingency which attempts to explain how harmful gene sweeps occur in evolution and why certain species became extinct when they really shouldn't have, eg Marsh Hen and Mososaur.
It doesn't mean that the people using these theories are charlatans. It means that the people thinking them came up with the ideas within the current state of knowledge and their thought processes which are, after all, human and limited no matter how clever they are.
"More cosmic observations and research will need to be undertaken to establish whether this new object is indeed something that has never been observed before or whether it may instead be the lightest black hole ever detected."
A call for more research, or in other words money.
