THE END
OF
DARK MATTER
IS COMING
The hypothesis of the existence of dark maer
was refuted by the result of an experiment
published two weeks ago.

Xenon is special, explained experiment physics coordinator Aaron
Manalaysay, because it allows researchers to see if a collision is with one
of its electrons or with its nucleus. If something hits the nucleus, it is more
likely to be the dark matter that everyone is looking for, he said.
These scientists tried a similar, smaller experiment here years ago. After
coming up empty, they figured they had to go much bigger. Another large-
scale experiment is underway in Italy run by a rival team, but no results
have been announced so far.
"It is essentially impossible to understand our observation of history, of the
evolutionary cosmos without dark matter," Manalaysay said.
Lippincott, a University of California, Santa Barbara, physicist, said "we
would not be here without dark matter."
So while there's little doubt that dark matter exists, there's lots of doubt
about what it is. The leading theory is that it involves things called WIMPs
—weakly interacting massive particles.
If that's the case, LUX-ZEPLIN could be able to detect them. We want to
find "where the wimps can be hiding," Lippincott said.
Second experiment:
The possibility that dark matter exists
in the form of a dark massive photon
at
University Adelaide's School of Physical Sciences

One key approach is the Sodium Iodide with Active Background Rejection
Experiment (SABRE) that is being built in a new laboratory in a former
gold mine one kilometer underground in Stawell, Victoria. It is being
constructed in collaboration with researchers in Australia, Europe, and the
United States, and in a few years' time it will hopefully shed light on this
question.
Professor Thomas's latest work with colleagues Dr. Xuangong Wang and
Professor Anthony Williams from the University Adelaide's School of
Physical Sciences, published in the journal Physical Review Letters ,
explores the possibility that dark matter exists in the form of a dark massive
photon.
"We are exploring the discovery potential of a new tool, parity violating
electron scattering, which has been enabled by the upgrade at Thomas
Jefferson National Accelerator Facility (JLab) in the United States," said
Professor Thomas.
"Parity violation is like looking at the difference between what happens in
the laboratory and what happens when you view the experiment in a mirror.
The differences are very small, typically less than a part per million, but
incredibly precise measurements enable us to observe this and use it as a
signal of the existence of this new particle.
"We found a mysterious result for the size of a lead nucleus which may be
explained if there is a particular new dark matter particle, the dark photon.
"New experiments where changes in the predictions without any dark
matter could be modified by as much as five percent, with the difference
providing direct evidence for this type of dark matter."
Knowledge about this new particle from Professor Thomas's work may
help explain a surprising discrepancy that has been inferred from
experiments at JLab between the neutron density in a lead nucleus and that
predicted by nuclear structure theory.
"A vital test of the existence of such a particle could be provided by future
experiments into the behavior of electrons, positrons and deuterons," he
said.
"Visible matter is just the tip of the iceberg. With a better understanding of
dark matter, the part of the iceberg below the surface, we will shine a light
on the secrets of our universe."
<<<<<<<<<<<<<<<<<<<111<<<<<<<<<<<<<<<<<<<<
Let's analyze the results of such experiments that try to prove the
hypothesis of the existence of dark matter.
First of all, can we be sure that dark matter is the only possible solution to
explain the violation of Universal Gravitation by galaxies?
Well, if current theories were one hundred percent in affinity with
the behavior of phenomena observed through experiments, we
could say, categorically and DEFINITELY that YES, only
through dark matter can there be an explanation for the violation
of Universal Gravity.
