Showing results for "Dark" in Physics

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.

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature.

Dark Emu argues for a reconsideration of the 'hunter-gatherer' tag for pre-colonial Aboriginal Australians and attempts to rebut the colonial myths that have worked to justify dispossession. Accomplished author Bruce Pascoe provides compelling evidence from the diaries of early explorers that suggests that systems of food production and land management have been understated in modern retellings of Aboriginal history, and that a new look at Australia's past is required.

Imagine you’re trying to build the biggest, most awesome LEGO castle ever. You gather all your colorful bricks—the reds, blues, yellows, and greens. You plan your design, start stacking the bricks, and build towers, walls, gates, and secret tunnels. Everything’s going great. But suddenly, something odd starts to happen. Parts of your castle stick together more tightly than they should. Some towers refuse to fall over, no matter how much you poke them. And even stranger, the whole play area you’re building on starts stretching.

From a star theoretical physicist, “a love letter to the wonderous universe we call home, and an urge to think critically about how we explore its depths” (Smithsonian Magazine) In The Disordered Cosmos, Dr. Chanda Prescod-Weinstein shares her love for physics, from the Standard Model of...

The ordinary atoms that make up the known universe - from our bodies and the air we breathe to the planets and stars - constitute only 5 percent of all matter and energy in the cosmos. The rest is known as dark matter and dark energy, because their precise identities are unknown. The Cosmic Cocktail is the inside story of the epic quest to solve one of the most compelling enigmas of modern science - what is the universe made of? - told by one of today’s foremost pioneers in the study of dark matter.

A breakout bestseller in Italy, now available for American listeners for the first time, Genesis: The Story of How Everything Began is a short, humanistic tour of the origins of the universe, earth, and life—drawing on the latest discoveries in physics to explain the seven most significant...

Whether searching for extra-terrestrial life, managing the effects of space weather or learning about dark matter, the study astrophysics has profound implications for us all. NASA scientist and astronomer Sten Odenwald explains the key concepts of this vast topic, bringing clarity to some of the great mysteries of space.

On July 23, 1999, the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built, was launched aboard the space shuttle Columbia. Since then, Chandra has given us a view of the universe that is largely hidden from telescopes sensitive only to visible light. In Chandra's Cosmos, Wallace H. Tucker uses a series of short, connected stories to describe the telescope's exploration of the hot, high-energy face of the universe.

Whether it's from dodgy acronym-titled crime shows to news stories designed to terrify you down to your socks, we've all heard about sites like Silk Road and the ways criminals use cryptocurrency online. But did you know that among the various shady corners of the dark web you can also find portals to the BBC and Facebook? So, let's go on a journey from the birth of the Net through the strangest dark services to the surprisingly positive uses of dark technology, including dodging the watchful eye of oppressive censors.

Our historians today often only emphasize negative interactions between the races, and dismally fail to relay a COMPLETE HISTORY, which tells of how the noble ones of all races protected and helped one another in our country. From the inspiring examples of parents, grandparents, and ancestors, Debra undoubtedly drew strength. Many of their stories are in the opening chapters of the book. The narrative continues through the turbulent 1960s and 1970s.

In a beautifully written, science-packed, and inspirational memoir, Egyptian-American astrophysicist Sarafina El-Badry Nance shares how she boldly carved out a place in the field of astrophysics, grounding herself in a lifelong love of the stars to face life’s inevitable challenges and embrace...

A fatal flaw in the most fundamental model of nature has been overlooked for so long that many people do not question it. The transverse wave model of photons has failed at almost every prediction its proponents made. And the proof of its validity as a model for photons has failed to consider that longitudinal waves accomplish the same thing in most experiments. Don't ignore the inconvenient facts that oppose your model.
