A bracing pleasure for Earth-science buffs and readers interested in diving into deep history.
A tour of the past worlds that the geological history of Earth reveals.
British paleontologist and evolutionary biologist Halliday roams the globe to examine the geological maxim that Earth’s past is its present and future—that the processes that once placed the continents into a single supermass will do so again. He begins along the banks of the Thames, which “now enters the sea more than 100 miles south of where it used to flow” thanks to changing sea levels in times of glaciation and glacial melt: Britain was once a tropical swamp. The author recognizes that geologic time is mind-boggling given a record of life that stretches back 4 billion years and a planet another half-billion years older than that. He takes pains, therefore, to write with clarity about what is “directly observable from the fossil record,” allowing for a few alternate theories and surprises. One of the latter is his observation that grasses are only 70 million years old, meaning that grassland animals are younger than that. He chronicles his travels to oddball geological places such as Italy’s Gargano Peninsula, which really belongs out in the middle of the ocean and which was populated “over the water, with ancestrally small animals—mice and dormice, for example, blown across on bits of floating plant, and birds flying over.” The monkeys that made their ways from Africa to South America had a tougher journey, crossing more than 1,000 miles of sea long after the continents broke apart 140 million years ago. Halliday brings good news: After periods of mass extinction come mass flourishing: “A new age begins, with new gods, and new worlds. After death, life; after extinction, speciation.” The bad news: Humans are likely toast all the same.

Solid data and reasoned conjecture strike a harmonious balance in a new SETI.
A jocular title does not even hint at the real wonders of this cook’s tour of alien life.
Astrophysicist Frank, author of Light of the Stars and The Constant Fire, has been obsessed with the idea of extraterrestrial life since childhood. After years of dreaming about exploring the cosmos for signs of intelligent life, he and other scientists are on the threshold of a new era of unprecedented discovery in the field of astrobiology. He details not only recent revelations in the detection of exoplanets, but also the search for technosignatures, indicators of technologically advanced species on worlds light years distant. These are not merely elements of science fiction. They are realities now within human reach thanks to the continuing development of ultra-powerful telescopes and to the sea change in a scientific culture that once scoffed at the Search for Extraterrestrial Intelligence (SETI). Frank’s enthusiasm is contagious, occasionally over-exuberant, and there is plenty of hard science in this survey, which the author presents with economy and accessibility. The book brims with fascinating facts and speculations, from the particulars of astrobiology to Dyson spheres. Frank’s cosmic tour makes stops at such milestones as the Fermi Paradox and the Drake Equation, showing how these 1950s advances continue to inform our thinking about the possibility of technological civilizations. The author also recounts the origins and current manifestations of the UFO craze and how the advancement of actual science has been impeded by 70 years of pop culture images that haunt our collective expectations. Frank advises we look for alien life where it most likely exists: deep space. He also stresses the key point that we have only begun to peer into the universe with instruments capable of breakthrough discoveries, a useful riposte to critics of the effort. Throughout, Frank champions the importance of demanding standards of evidence: “They are, literally, why science works.”

A solid foundational education in a handful of lively scientific topics.
Two science podcasters answer their mail.
In this illustrated follow-up to We Have No Idea: A Guide to the Unknown Universe (2017), Cham, a cartoonist and former research associate and instructor at Caltech, and Whiteson, professor of physics and astronomy at the University of California, Irvine, explain the basic science behind subjects that seem to preoccupy the listeners of their podcast, Daniel and Jorge Explain the Universe. Most of the questions involve physics or astrophysics and take the form of, is such-and-such possible?—e.g., teleportation, alien visitors, building a warp drive, entering a black hole). The authors emphasize that they are answering as scientists, not engineers. “A physicist will say something is possible if they don’t know of a law of physics that prevents it.” Thus, a spaceship traveling fast enough to reach the nearest star in a reasonable amount of time is not forbidden by the laws of physics, but building one is inconceivable. Similarly, wormholes and time travel are “not known to be impossible”—as are many other scenarios. Some distressing events are guaranteed. An asteroid will strike the Earth, the sun will explode, and the human race will become extinct, but studies reveal that none are immediate threats. Sadly, making Mars as habitable as Earth is possible but only with improbably futuristic technology. For those who suspect that we are living in a computer simulation, the authors describe what clues to look for. Readers may worry that the authors step beyond their expertise when they include chapters on the existence of an afterlife or the question of free will. Sticking closely to hard science, they deliver a lucid overview of brain function and the debate over the existence of alternate universes that is unlikely to provoke controversy. The authors’ work fits neatly into the recently burgeoning market of breezy pop-science books full of jokes, asides, and cartoons that serve as introductions to concepts that require much further study to fully understand.
