What will happen if humanity makes contact with another civilization on a different planet? In The Contact Paradox, space journalist Keith Cooper tackles some of the myths and assumptions that underlie SETI--the Search for Extraterrestrial Intelligence.In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.The silence from the stars is prompting some researchers, inspired by the Arecibo transmission, to transmit more messages into space, in an effort to provoke a response from any civilizations out there that might otherwise be staying quiet. However, the act of transmitting raises troubling questions about the process of contact. We look for qualities such as altruism and intelligence in extraterrestrial life, but what do these mean to humankind? Can we learn something about our own history when we explore what happens when two civilizations come into contact? Finally, do the answers tell us that it is safe to transmit, even though we know nothing about extraterrestrial life, or as Stephen Hawking argued, are we placing humanity in jeopardy by doing so?In The Contact Paradox, author Keith Cooper looks at how far SETI has come since its modest beginnings, and where it is going, by speaking to the leading names in the field and beyond. SETI forces us to confront our nature in a way that we seldom have before--where did we come from, where are we going, and who are we in the cosmic context of things? This book considers the assumptions that we make in our search for extraterrestrial life, and explores how those assumptions can teach us about ourselves.

    More than a possibility, it is becoming a necessity: whether our hand is forced by climate change and resource depletion or whether future catastrophes compel us to abandon Earth, one day we will make our homes among the stars.World-renowned physicist and futurist Michio Kaku explores in rich, accessible detail how humanity might gradually develop a sustainable civilization in outer space. With his trademark storytelling verve, Kaku shows us how science fiction is becoming reality: mind-boggling developments in robotics, nanotechnology, and biotechnology could enable us to build habitable cities on Mars; nearby stars might be reached by microscopic spaceships sailing through space on laser beams; and technology might one day allow us to transcend our physical bodies entirely.With irrepressible enthusiasm and wonder, Dr. Kaku takes readers on a fascinating journey to a future in which humanity could finally fulfil its long-awaited destiny among the stars - and perhaps even achieve immortality.

    But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead.At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering.This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy.

    David W. Brown chronicles the remarkable saga of how Europa was won, and what it takes to get things done—both down here, and up there.

    There are permanent populations established on the Moon, Venus and Mars. Outer space inhabitants have formed a new political entity, the Federation, and between the Federation and Earth a growing rivalry has developed. EARTHLIGHT is the story of this emerging conflict.

    The Star Kingdom's ally Erewhon is growing increasingly restive in the alliance because the new High Ridge regime ignores its needs. Add to that the longstanding problem of a slave labor planet controlled by hostile Mesans in Erewhon's stellar back yard, a problem which High Ridge also ignores. Finally, the recent assassination of the Solarian League's most prominent voice of public conscience indicates the growing danger of political instability in the Solarian League - which is also close to Erewhon. In desperation, Queen Elizabeth tries to defuse the situation by sending a private mission to Erewhon led by Captain Zilwicki, accompanied by one of her nieces. When they arrive on Erewhon, however, Manticore's most capable agent and one of its princesses find themselves in a mess. Not only do they encounter one of the Republic of Haven's most capable agents - Victor Cachat - but they also discover that the Solarian League's military delegation seems up to its neck in skullduggery. And, just to put the icing on the cake, the radical freed slave organization, the Audubon Ballroom, is also on the scene - led by its most notorious killer, Jeremy X.
