Researcher: The search for dark matter has become a “quagmire of confirmation bias”

From science writer Bruce Dorminey at Forbes:

Time may be running out on the search for the cosmos’ exotic dark matter. Decades after the first searches for dark matter’s hypothetical exotic particle counterparts, researchers are mostly at a loss to explain why there still has been no direct detection. That is, one that could explain why such unseen, dark matter particles only appear to weakly interact with normal matter.

McGaugh says one huge problem is that while dark matter theory is ‘confirmable’ it is not ‘falsifiable’ as a scientific theory should be.

“There is no clear way to know [that] what you’re looking for — but failing to find — doesn’t exist at all,” said McGaugh. “If you’re convinced it must [exist], you’ll go on looking forever.”

There’s no exit strategy, says McGaugh. Indeed, he says his colleagues have heedlessly blown through many experiential markers which they have chosen to ignore.

“The search for dark matter has become a quagmire of confirmation bias,” McGaugh concludes. More.

So many research areas in science today are hitting hard barriers that it is reasonable to think that we are missing something.

A proposed dark matter solution makes gravity an illusion


Proposed dark matter solution: “Gravity is not a fundamental governance of our universe, but a reaction to the makeup of a given environment.”

This somewhat parallels the search for the random, undirected origin of life. As long as people assume that it must exist they'll search for it endlessly. It's like searching for the lost island of unicorns. Every horse, narwhal, volcano, and story is "evidence" of getting closer to what will never be found. The divergence is that while dark matter may or may not exist, the possibility of its existence isn't entirely irrational (insane) while believing and even insisting that self-reproducing entities with complexity that dwarfs that of any human technology somehow just happened in a warm puddle (or ice, or a thermal vent, or space, etc.) is disconnected from and contradictory to all of known reality, and is therefore both irrational and insane.
