The current cosmological model only works by postulating the existence of dark matter – a substance that has never been detected, but that is supposed to constitute approximately 25% of all the universe. But a simple test suggests that dark matter does not in fact exist. If it did, we would expect lighter galaxies orbiting heavier ones to be slowed down by dark matter particles, but we detect no such slow-down. A host of other observational tests support the conclusion: dark matter is not there. The implications of this are nothing short of a revision of Einstein’s theory of gravitation. Why the scientific community is in denial about the falsification of the dark matter model is a question that requires both a sociological and philosophical explanation, argues Pavel Kroupa.
Astronomers and physicists today understand the observed Universe in terms of a model universe in which the normal matter we see around us in the form of atoms makes up only 5% of all the energy in it. About 20% is made up of exotic dark matter particles and about 75% is made up of even more exotic dark energy. This dark-matter-based model (for each gram of normal matter there are 25 grams of the exotic dark matter) is about 20 years old, but the strong belief in the scientific community that dark matter exists goes back 30 years.

There is a simple test that these scientists are ignoring and which has already been applied and it tells us that dark matter does not exist.

The many searches worldwide for evidence of dark matter particles, going on since at least 30 years, have come up empty handed, and yet today the scientists are even more convinced that dark matter rules the Universe. This dark matter can be extremely light weight "fuzzy" particles that are extended over thousands of light years, or it may be made up of particles that are heavier, such as "weakly interacting massive particles" (WIMPS), or even primordial black holes that formed from exotic physical processes during the Big Bang. The theory of dark matter makes no predictions as to what the particles ought to be and what to look for, and so a very large number of scientists searching for it with laboratories and experiments deep under ground, in the polar regions or in space and in all countries try to prove the existence of dark matter particles and to get the Nobel Prize. Many tens of millions of tax-payer dollars are being used up each year on this search.

But there is a simple test that these scientists are ignoring and which has already been applied and it tells us that dark matter does not exist. This test goes back to Subrahmanyan Chandrasekhar who, in 1943, showed that a massive body (e.g. a dwarf galaxy) that moves through a background of comparatively low mass particles (e.g. dark matter particles), will slow down. This process of "Chandrasekhar dynamical friction" is exceedingly well understood. It is the same physical mechanism by which our space craft are slingshot to the distant realms of the Solar System, by them first passing close-by a planet (e.g. Venus) in the inner Solar System, the planet slowing down a tiny little bit after the encounter, while the comparatively light-weight probe gets catapulted away, e.g. towards Pluto. A satellite galaxy slingshots myriads of dark matter particles to more distant regions around the major galaxy and so slows down and sinks towards the major galaxy to merge with it.
