“Dr HongSheng Zhao, of the University’s School of Physics and Astronomy, has shown that the puzzling dark matter and its counterpart dark energy may be more closely linked than was previously thought. Only 4% of the universe is made of known material – the other 96% is traditionally labelled into two sectors, dark matter and dark energy. A British astrophysicist and Advanced Fellow of the UK’s Science and Technology Facilities Council, Dr Zhao points out, ‘Both dark matter and dark energy could be two faces of the same coin.
‘As astronomers gain understanding of the subtle effects of dark energy in galaxies in the future, we will solve the mystery of astronomical dark matter at the same time. Astronomers believe that both the universe and galaxies are held together by the gravitational attraction of a huge amount of unseen material, first noted by the Swiss astronomer Fritz Zwicky in 1933, and now commonly referred to as dark matter. Dr Zhao reports that, “Dark energy has already revealed its presence by masking as dark matter 60 years ago if we accept that dark matter and dark energy are linked phenomena that share a common origin.’
