Cosmologists should be more skeptical of dark matter

To get computer models to look similar to the Universe around us, cosmologists have assumed that around 96 per cent of matter and energy are in forms that we cannot directly detect. You might think that this would make cosmologists wary of relying on such hypothetical substances. Yet for the majority working today, dark matter and dark energy are every bit as real as the stars and galaxies that we can see.
