Fermi researcher: Dark matter field is in a state of “major disruption.” Rob Sheldon comments

Hubble image captures what dark matter is supposed to be.

Whatever dark matter is, is not what was expected. From Dan Hooper at Physics:

The latest results from two dark matter searches have further ruled out many theoretically attractive dark matter particle candidates.

The lack of a definitive detection of dark matter particles, in both underground experiments and at the Large Hadron Collider [4–7], has had a palpable effect on the community of scientists that study particle dark matter. Even though a discovery could very plausibly be right around the corner, there is a widespread view that many of the most theoretically attractive candidates for dark matter should have been detected by now, based on their predicted properties. In the absence of such a discovery, the field has begun to redirect efforts toward new, and sometimes very different, ideas. Although this state of affairs can certainly be frustrating at times, it has also had the positive effect of ushering in an explosion in dark matter model building.

Because of the progress of experiments such as XENON1T and PandaX-II, the field of dark matter research is currently in a state of major disruption. The dark matter, it turns out, is not what many of us in the particle theory community imagined it was likely to be. With this disruption, however, has come both great excitement and great opportunity. We know much more about dark matter’s nature than we did only a few short years ago. And the years ahead offer considerable promise for further advances, and perhaps with a little luck, the discovery that so many of us have been waiting for. More.

Our physics color commentator Rob Sheldon offers,

Dark matter WIMP searches are coming to a close with a bang. $M is being spent on 3, humongous, underground Xenon experiments, each bigger than the last. US was first to report with its LUX experiment, $10M 370kg of Xe, then comes China with its 584kg of Xe, and finally EU with its 2000kg of Xe. These experiments are millions of times more sensitive than previous searches, and could detect one event per year.

What have they seen?

Nothing.

How do these nations justify the spending?

Nice spin, but I sure wish they would spend that money for more lucrative goals—The Philosopher’s Stone, for example. Sounds like Sabine Hossenfelder’s criticism is valid–our education system is cranking out bad theoretical physicists. I would add, “bad metaphysicists” too.

Are we really closing in on dark matter? At this point, it may be useful to stop and ask, is there a date on dark matter’s IOU? Is there any point at which we can reevaluate without starting a blame circus? Because, if not, this is really a quest for something in inner space, not outer space and it is not clear what we are looking for.

    more like ‘whatever dark matter is not’ because it is not.
    SPIRAL cosmological redshift hypothesis (CR) explains why CR is not evidence of ongoing cosmic expansion, rather it is evidence of SPIRAL ‘s ID cosmology model that falsifies all deep-time dependent premise and assumptions..

    The dark matter hypothesis is obviously a ruse to hide the falsification of both Newtonian Gravity Theory and General Relativity. After centuries of debate, physicists still have no idea what causes gravitational attraction. But they are busy conjuring up undetectable entities and spending billions of dollars of our money pretending to find gravitational waves in spacetime. They apparently never got the news that “spacetime is a block universe in which nothing happens” (Karl Popper).

    Physics is a farce.

    @2 FourFces,

    Good point! I have always wondered about the causes of gravitational attraction…

    What do you think of dark energy? Some believe that dark energy is a property of space but I think it could be the other way around…If that is the case, then dark energy could explain the gravitational attraction…

    Dark energy could also be responsible for the missing “dark matter” in the universe since all prediction what dark matter supposed to be have failed…

    Any thoughts?

    @J-Mac,

    IMO, both dark matter and dark energy are modern fairy tales. Dark matter was invented in order to deny the falsification of both general relativity and Newtonian gravity theory. Neither can explain what causes gravity. Obviously, it is not mass that causes it. Most of the mass is unaccounted for.

    Dark energy was conjured up to explain the red shifting of distant stars and galaxies. Physicists misinterpret this red shifting to mean that the universe is expanding and that this expansion is accelerating. You need lots of energy to explain this accelerated expansion.

    It’s all bogus, IMO.

    @5 FF

    So, you think the universe is neither expanding nor accelerating???

    If that’s the case, what’s your evidence for that?

    J-Mac @6,

    I just think that the reason given by the physics community to support the accelerated expansion hypothesis is fallacious. Light is red shifted over huge distances, not because their source is accelerating away from us but because photons lose part of their energies over time. This has to do with the true nature of motion, i.e., the true cause of motion. However, this is beyond this discussion.
