All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced.
Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together.
That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster.
Across the universe, this requires enough energy that the equivalent mass would be nearly 14 times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

My only gripe is that with an audio book the delivery is so massively important and wrongly pronounced words and terms are really jarring to the ear .
It speaks of either lack of research or average delivery . I’m not sure if the reader is a scientist or just a voice actor . But hearing “ Nuculer” for Nuclear , ManGENELIC instead or Magellanic and at least 3 ways or pronouncing Cepheid does take away from the immersive experience
Great info with dubious pronunciations

Very interesting

This book simply presents the most contemporary theories. It asks the reader to decide for themselves.
