Rédigés par Becky Smethurst, astrophysicienne à l'université d'Oxford, les dix petits textes qui composent ce livre vous guideront à travers les galaxies et les trous noirs, et vous raconteront pourquoi la matière noire est l'une des énigmes les plus fascinantes du cosmos. Vous apprendrez...

For half a century, cosmology has relied on two invisible ingredients to explain the universe: dark matter, a substance that has never been detected despite decades of experimental search, and dark energy, a repulsive force whose physical nature remains entirely unknown. Together, they are said to constitute ninety-five percent of the cosmos. The remaining five percent—ordinary atoms, light, everything we have ever touched or measured—is treated as a minor addendum to a universe made mostly of darkness. This textbook presents a different cosmology. It is not speculative.

The iron in your blood was forged in the nuclear furnace of a dying star. The gold in your jewelry was born in the collision of neutron stars so violent it sent ripples through spacetime itself. The carbon in your DNA survived a stellar explosion and a billion-year journey through space before becoming part of you. Born from Catastrophe reveals the extraordinary truth behind these statements: we are not just made of stardust, but of stardust created through the most violent events in the universe.

When molecular biologist Becky McClain raised urgent alarms about biosafety lapses at her biotech lab at Pfizer, she expected concern—not retaliation. Instead, her warnings about dangerous, genetically engineered viruses that were handled without following standard safety protocols were met with hostility, intimidation, and ultimately, devastating illness after a workplace exposure changed her life forever.

Sir Isaac Newton famously complained about action at a distance. How was it possible, he wrote, that gravity, or attraction, operated between objects without physical contact? Well, jump to the twenty-first century, and we have a lot more to say about that. Listeners will enjoy a brilliant, outrageous, playful exploration of quantum physics in everyday life, from a secret interplay of TV plots with us, in electricity, to other speculations, founded in the authors decades of initiations as well as being an original thinker and a scholar.

This audio edition is narrated with dazzling enthusiasm by the author, Dr Becky Smethurst. Right now, you are orbiting a black hole. The Earth orbits the Sun, and the Sun orbits the centre of the Milky Way: a supermassive black hole, the strangest and most misunderstood phenomenon in the galaxy...

Discover the essential wisdom of ancient and modern regenerative practices to build long-lasting soil fertility, healthy ecosystems, and nutrient-dense food—year after year.

Presenters Becky Ripley and Emily Knight mull over a multitude of bewildering and brain-teasing questions as they try to make sense of what we humans are all about - with a little help from some other species. What can the swirling patterns in a starling murmuration tell us about the way our ideas spread? Can ants teach us anything about avoiding a pandemic? And how could a brainless single-cell slime mould help to solve our trickiest problems?

What if meaning wasn’t missing—but misassigned? The Silence That Spoke in Symbols is not a sequel, but a continuation. It picks up not where the story ends, but where language itself collapses. Following the quiet tremors left by The Shatter That Called Itself an Unraveling, A.J. Salara returns with a haunting meditation on language, symbolism, and the illusions we call sacred. This is not a book about healing, resolution, or narrative redemption. It does not tell you who you are, or how to reclaim what you lost. Instead, it sits beside you while the scaffolding of self slips away.
