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 75% of 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.
