One of America's most talked-about science writers--and author of the award-winning book, Thursday's Universe--explores the phenomenon of "dark matter", the hypothesized, invisible substance that is changing our view of the universe. Photographs.
An unparalleled history of astronomy presented in the words of the scientists who made the discoveries. Here are the writings of Copernicus, Galileo, Kepler, Newton, Halley, Hubble, and Einstein, as well as that of dozens of others who have significantly contributed to our picture of the universe. From Aristotle's proof that the Earth is round to the 1998 paper that posited an accelerating universe, this book contains 100 entries spanning the history of astronomy. Award-winning science writer Marcia Bartusiak provides enormously entertaining introductions, putting the material in context and explaining its place in the literature. Archives of the Universe is essential reading for professional astronomers, science history buffs, and backyard stargazers alike.
The riveting and mesmerizing story behind a watershed period in human history, the discovery of the startling size and true nature of our universe. On New Years Day in 1925, a young Edwin Hubble released his finding that our Universe was far bigger, eventually measured as a thousand trillion times larger than previously believed. Hubble’s proclamation sent shock waves through the scientific community. Six years later, in a series of meetings at Mount Wilson Observatory, Hubble and others convinced Albert Einstein that the Universe was not static but in fact expanding. Here Marcia Bartusiak reveals the key players, battles of will, clever insights, incredible technology, ground-breaking research, and wrong turns made by the early investigators of the heavens as they raced to uncover what many consider one of most significant discoveries in scientific history.
From the history of the science to the cutting edge of knowledge and technology, the story of modern astrophysics is told through interviews with and profiles of leading scientists and theoreticians.
To the eyes of the average person and the trained scientist, the night sky is dark, even though the universe is populated by myriads of bright galaxies. Why this happens is a question commonly called Olbers' Paradox, and dates from at least 1823. How dark is the night sky is a question which preoccupies astrophysicists at the present. The answer to both questions tells us about the origin of the universe and the nature of its contents ? luminous galaxies like the Milky Way, plus the dark matter between them and the mysterious dark energy which appears to be pushing everything apart. In this book, the fascinating history of Olbers' Paradox is reviewed, and the intricate physics of the light/dark universe is examined in detail. The fact that the night sky is dark (a basic astronomical observation that anybody can make) turns out to be connected with the finite age of the universe, thereby confirming some event like the Big Bang. But the space between the galaxies is not perfectly black, and data on its murkiness at various wavelengths can be used to constrain and identify its unseen constituents.
The award-winning science writer “packs a lot of learning into a deceptively light and enjoyable read” exploring the contentious history of the black hole (New Scientist). For more than half a century, physicists and astronomers engaged in heated dispute over the possibility of black holes in the universe. The strange notion of a space-time abyss from which not even light escapes seemed to confound all logic. Now Marcia Bartusiak, author of Einstein’s Unfinished Symphony and The Day We Found the Universe, recounts the frustrating, exhilarating, and at times humorous battles over one of history’s most dazzling ideas. Bartusiak shows how the black hole helped revive Einstein’s greatest achievement, the general theory of relativity, after decades of languishing in obscurity. Not until astronomers discovered such surprising new phenomena as neutron stars and black holes did the once-sedate universe transform into an Einsteinian cosmos, filled with sources of titanic energy that can be understood only in the light of relativity. Black Hole explains how Albert Einstein, Stephen Hawking, and other leading thinkers completely changed the way we see the universe.
Set in the universe of Star Trek: The Next Generation, a doorway is opened from another universe and the crew of the U.S.S Enterprise must battle their toughest enemy yet—themselves. One hundred years ago, four crewmembers of the U.S.S EnterpriseTM crossed the dimensional barrier and found a mirror image of their own universe, populated by nightmare duplicates of their shipmates. Barely able to escape with their lives, they returned, thankful that the accident which had brought them there could not be duplicated, or so they thought. But now the scientists of that empire have found a doorway into our universe. Their plan is to destroy from within, to replace a Federation Starships with one of their own. Their victims are the crew of the U.S.S. Enterprise NCC-1701-D, who now find themselves engaged in combat against the most savage enemies they have ever encountered, themselves.
The universe has many secrets. It may hide additional dimensions of space other than the familier three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now. Warped Passages is a brilliantly readable and altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature—taking us into the warped, hidden dimensions underpinning the universe we live in, demystifying the science of the myriad worlds that may exist just beyond our own.
The story is so improbable, it can only be true: A brilliant woman with a long history of mental illness—who once proclaimed herself to be "the center of the universe" — is miraculously cured by accidental carbon monoxide poisoning aboard the family boat. Nancy Bachrach warns readers, “Don’t try this at home” in her darkly humorous memoir about “the second coming” of her mother — the indomitable Lola, whose buried family secrets had been driving her crazy. Aching and tender, unflinching and wry, The Center of the Universe is a multigenerational mother-daughter story—a splendid, funny, lyrical memoir about family, truth, and the resilience of love.
RIDDING THE WORLD OF EVIL, ONE ALIEN AT A TIME. In a time and place not too far away, Mia Snow is an alien huntress for the New Chicago Police Department, and she's the perfect girl for the job. Tough and sexy, she's earned each of her scars battling the elusive enemy among us. Now, investigating a series of killings, she is shaken to the core when a burst of violence leaves her partner Dallas fighting for his life.
