About this listen
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.

And it’s well read for the most part, by the narrator who’s accent (speaking as a northern Englishman myself) is refreshing to hear. HOWEVER! I’m no grammar Nazi, but for crying out loud! You would think that for a book which uses words like, “nucleon,” “nuclear,” and, “nucleus,” with such frequency throughout its entirety, the producer might have taken the time to teach the narrator how to SAY the damned words!?
At first you ignore it, but it happens so often that it starts to grate, until it becomes a continual distraction. For a scientist’s published book on physics, it’s unacceptable to allow the narrator to teach younger listeners to say words wrongly, isn’t it? Especially over and over again. If you can say, “new,” and, “clear,” you can say, “nuclear!” Not, “new-killer.” It’s not an accent thing, nor a speech impediment. It’s simply a lazy mistake that should never have been put out as a final recording with the errors repeatedly annoying the listener and teaching countless people to mispronounce scientific terms! . . . Any more than a printed version of this book would never have been published with the words misspelled in that way!
So, this dreadful oversight, rendered egregious by the sheer number and variety of its repetitions, sadly mars an otherwise well narrated book. I can’t understand how it was allowed to get past basic quality control, let alone any producer, who seems not to have been asleep at the wheel?
This is certainly NOT the level of quality I have come to expect from Audible. And it’s such a shame, as I imagine the author must feel rather aggrieved, or would if he’s heard the whole recording? It’s not like this book was free either! I payed money to have my intelligence insulted! Come on Audible? Check your products BEFORE we pay for them?
