The Life and Death of Planet Earth (full title: The Life and Death of Planet Earth: How the New Science of Astrobiology Charts the Ultimate Fate of Our World) is a popular science book by paleontologist Peter Ward and astronomer Donald E. Brownlee. Released in 2003, the book picks up where Rare Earth leaves off, this time talking about why the Earth's ability to support complex and, especially, intelligent life is not just rare in space, but also in time.
The book discusses Earth's future and eventual demise as it is ultimately destroyed by a warming and expanding Sun. The Earth's lifespan is compared to that of a living being, pointing out that the systems which keep it habitable will gradually break down one by one, like the organs in an aging human body. The book also illustrates Earth's eventual fate by compressing its full 12 billion-year history into 12 hours on a clock, with the first life appearing at 1:00 am, the first animals and plants appearing at 4:00 am, and the present day being 4:29.59 am. The Earth is destroyed by the Sun at "high noon", though animals and plants come to an end by 5:00 am. The book also suggests that not only will Earth eventually become uninhabitable to complex life long before it finally gets destroyed by the Sun's red giant stage, it also implies that intelligent life will probably die out even much sooner, and that not only microbial life were the first life forms to appear, they will also eventually be the last surviving life forms on Earth to still remain in the distant future before they too finally disappear.
David Hughes of New Scientist said it was both riveting and provoked thoughts of doom. [1] Fraser Cain called the book depressing on Universe Today , but said that the authors "tell an engaging story" and that the scientific terminology used is well explained. [2] Publishers Weekly said that the authors do not make an airtight case, though "they do deftly bring together findings from many disparate areas of science in a book that science buffs will find hard to put down". [3] The verdict of Kirkus Reviews was "Far from cheerful, but fascinating", while pointing out that the authors tended to move quickly from fact to their own personal theories, and that the prose was not of the highest standard. [4] The Oxford Mail quipped, "The joy of writing books about the next billion years is that no one will confront you with your mistakes". [5]
Astrobiology is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events. As a discipline, astrobiology is founded on the premise that life may exist beyond Earth.
The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy.
Extraterrestrial life, alien life, or colloquially simply aliens is life which does not originate from Earth. No extraterrestrial life has yet been conclusively detected. Such life might range from simple forms such as prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humanity. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life is known as astrobiology.
The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high likelihood of its existence. As a 2015 article put it, "If life is so easy, someone from somewhere must have come calling by now."
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole.
This is a bibliography of the books written or edited by Isaac Asimov, arranged alphabetically. Asimov was a prolific author, and he engaged in many collaborations with other authors. This list may not yet be complete. The total number of books listed here is over 500. Asimov died in 1992 at age 72; a small number of his books were published posthumously.
In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity such as sexually reproducing, multicellular organisms on Earth required an improbable combination of astrophysical and geological events and circumstances.
The Great Filter is the idea that in the development of life from the earliest stages of abiogenesis to reaching the highest levels of development on the Kardashev scale, there is a barrier to development that makes detectable extraterrestrial life exceedingly rare. The Great Filter is one possible resolution of the Fermi paradox.
John R. Gribbin is a British science writer, an astrophysicist, and a visiting fellow in astronomy at the University of Sussex. His writings include quantum physics, human evolution, climate change, global warming, the origins of the universe, and biographies of famous scientists. He also writes science fiction.
Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments hospitable to life. Life may be generated directly on a planet or satellite endogenously or be transferred to it from another body, through a hypothetical process known as panspermia. Environments do not need to contain life to be considered habitable nor are accepted habitable zones (HZ) the only areas in which life might arise.
Peter Douglas Ward is an American paleontologist and professor at the University of Washington, Seattle, and Sprigg Institute of Geobiology at the University of Adelaide. He has written numerous popular science works for a general audience and is also an adviser to the Microbes Mind Forum. In 2000, along with his co-author Donald E. Brownlee, he co-originated the term Rare Earth and developed the Medea hypothesis alleging that multicellular life is ultimately self-destructive.
David Darling is an English astronomer, freelance science writer, and musician. Darling has published numerous popular science works, including Life Everywhere: The Maverick Science of Astrobiology in 2001 and The Universal Book of Mathematics in 2004. He maintains the online Internet Encyclopedia of Science.
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor is the pervasive influence of technology introduced by humans, such as climate engineering, which could cause significant changes to the planet. For example, the current Holocene extinction is being caused by technology, and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes.
Dying Earth is a subgenre of science fantasy or science fiction which takes place in the far future at either the end of life on Earth or the end of time, when the laws of the universe themselves fail. Themes of world-weariness, innocence, idealism, entropy, heat death of the universe, (permanent) exhaustion/depletion of many or all resources, and the hope of renewal dominate. A related subgenre set in the distant future of entropic decay is called entropic romance.
Kepler-62f is a super-Earth exoplanet orbiting within the habitable zone of the star Kepler-62, the outermost of five such planets discovered around the star by NASA's Kepler spacecraft. It is located about 980 light-years from Earth in the constellation of Lyra.
The Living Cosmos: Our Search for Life in the Universe is a non-fiction book by the astronomer Chris Impey that discusses the subject of astrobiology and efforts to discover life beyond Earth. It was published as a hardcover by Random House in 2007 and as a paperback by Cambridge University Press in 2011.
Talking About Life: Conversations on Astrobiology is a non-fiction book edited by astronomer Chris Impey that consists of interviews with three dozen leading experts on the subject of astrobiology. The subject matter ranges from the nature and limits of life on Earth to the current search for exoplanets and the prospects of intelligent life in the universe. The book was published as a hardcover by Cambridge University Press in 2010.
Human Universe is a British television series broadcast on BBC Two, presented by Professor Brian Cox. An accompanying book was also published.
Rare Earth: Why Complex Life Is Uncommon in the Universe is a 2000 popular science book about xenobiology by Peter Ward, a geologist and evolutionary biologist, and Donald E. Brownlee, a cosmologist and astrobiologist. The book is the origin of the term 'Rare Earth Hypothesis' which denotes the central claim of the book: that complex life is rare in the universe.
Brief Answers to the Big Questions is a popular science book written by physicist Stephen Hawking, and published by Hodder & Stoughton (hardcover) and Bantam Books (paperback) on 16 October 2018. The book examines some of the universe's greatest mysteries, and promotes the view that science is very important in helping to solve problems on planet Earth. The publisher describes the book as "a selection of [Hawking's] most profound, accessible, and timely reflections from his personal archive", and is based on, according to a book reviewer, "half a million or so words" from his essays, lectures and keynote speeches.
