Dark matter search comes up empty

An online news reportfrom phys.org, titled “Scientists looking for invisible dark matter can’t find any,” reported the following:

Scientists have come up empty-handed in their latest effort to find elusive dark matter, the plentiful stuff that helps galaxies like ours form.

For three years, scientists have been looking for dark matter—which though invisible, makes up more than four-fifths of the universe’s matter—nearly a mile underground in a former gold mine in Lead, South Dakota. But on Thursday they announced at a conference in England that they didn’t find what they were searching for, despite sensitive equipment that exceeded technological goals in a project that cost $10 million to build.

Lead co-investigator Richard Gaitskell explains the experiment.

The experiment, called the Large Underground Xenon experiment or LUX, was found to be 4 times its original design sensitivity. It involves a detector that consists of about a third of a ton of supercooled xenon in a tank festooned with light sensors, each capable of detecting a single photon. As the so-called WIMPs (Weakly Interacting Massive Particles) pass through the tank, they should, on very rare occasions, bump into the nucleus of a xenon atom. Those bumps cause the nucleus to recoil, creating a tiny flash of light and an ion charge, both of which are expected to be picked up by LUX sensors.

The experiment is located in a hole a mile (1.6 km) underground in an old gold mine to exclude all sorts of background sources that might give false signals. The alleged dark matter particles are hardly affected by the intervening matter and pass mostly undisturbed through the planet, or so the theory alleges. But alas nothing has been detected. In fact for at least 40 years now no such local lab experiment has found anything.

Scientists are already starting to revamp the South Dakota mine site for a $50 million larger, higher-tech version of LUX, called LZ, that will be 70 times more sensitive and should start operations in 2020, said Brown University’s Richard Gaitskell, another scientific spokesman for LUX.1

Such is the mindset, that the elusive stuff must exist, that a new experiment is being designed without a shred of experimental evidence for its existence. The only basis for this type of thinking is from the cosmos.2 And the very survival of the big bang paradigm is at stake here. It has reached a state of a dark matter crisis now.

When observational data, for the alleged expansion of the universe, is compared to theory dark matter is needed as a fudge to make them agree.3  When the speeds of rotation of the spiral arms of galaxies is measured it has been found that hundreds of thousands of them rotate too fast and would cause the galaxies to fly apart in only a short time, cosmologically speaking. So it is assumed that these galaxies, including our own, are made up of a halo of invisible dark matter that is holding the galaxy together. Rarely is it even considered that the theory (i.e. the physics) might be wrong.

CM Title imageBut I suggest here that it is a failed paradigm and every failed experiment just digs the hole deeper. Pun intended.

The reason this is a failed paradigm is because it is based on a false foundation: that is, that the Universe is the product only of natural law and materialism, and that it has evolved to its current state over the past 13.8 billion years. I suggest that that is not the case, and though there may yet still be undiscovered particles, dark matter comprising 80% of all the matter in the Galaxy (yet is invisible) sounds more and more like a tall story than real physics.
