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.

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.

Space is the biggest, oldest, hottest, coldest, strangest thing a human can study. It's no surprise then, that the weirdest facts in science (not to mention the weirdest scientists themselves) are found in astrophysics and cosmology. If you're looking for instructions on how to set up your grandad's telescope this book probably isn't for you. In Astronomical, Tim James takes us on a tour of the known (and unknown) Universe, focusing on the most-mind boggling stuff we've come across, as well as unpacking the latest theories about what's really going on out there.

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.

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.

For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions - 98 percent of the human genome - were dismissed as ‘junk’. But in recent years researchers have discovered that variations in this ‘junk’ DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them.

In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times best-selling author of Warped Passages and Knocking on Heaven's Door uses her research into dark matter to illuminate the startling connections between the farthest reaches of space and life here on Earth.

Einstein's theory of gravity, as beautiful as it is, seems to be in direct contradiction with another theory he helped create: quantum mechanics. From the explosions of neutron stars and the collisions of black holes to the modern scientific process as a means to seek truth and understanding in the cosmos, this audiobook takes the listener on a journey of learning and discovery that has been 100 years in the making.

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.

What is matter? Matter is the stuff from which we and all the things in the world are made. Everything around us - from desks, to books, to our own bodies - are made of atoms, which are small enough that a million of them can fit across the breadth of a human hair. Inside every atom is a tiny nucleus and orbiting the nucleus is a cloud of electrons. The nucleus is made out of protons and neutrons, and by zooming in further, you would find that inside each there are even smaller particles: quarks.

As a child, Sarafina El-Badry Nance spent nearly every evening with her father gazing up at the flickering stars and pondering what secrets the night sky held. The daughter of an American father and Egyptian mother who both pushed her toward academic excellence, Sarafina dreamed of becoming an astronomer and untangling the mysteries of the stars overhead. But it wasn’t long before she was told, both explicitly and implicitly, that girls just weren’t cut out for math and science.

Whats really out there? How much do we actually know about the phenomena we cannot explain? Are we alone? Welcome to Dark Matters. A show solely dedicated to paranormal topics, with deep dives, discussions and fascinating facts all in. Hosted by Sigil Arts' Resident Enigma, Glitter!

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.

Hi everyone, John Hastings here. I am a comedian, you follow me on something or you are hearing this somewhere. I'm starting a new podcast called Questions with John Hastings. It's a short form audio and video podcast where I improvise around one question asked by an audience member. If you'd like to send me a question in anticipation of the show launching, it's johnhastingspodcast@gmail.com. Please subscribe, please rate, and please enjoy this podcast or don't.They're really short, so like if you hate it, it's still actually very manageable listening. Thanks.The trailer for Questions with ...
