内容简介
Aliens are big in America. Whether they’ve arrived via rocket,flying saucer, or plain old teleportation, they’ve been invading,infiltrating, or inspiring us for decades, and they’ve fascinatedmoviegoers and television watchers for more than fifty years. Abouthalf of us believe that aliens really exist, and millions areconvinced they’ve visited Earth.
For twenty-five years, SETI has been looking forthe proof, and as the program’s senior astronomer, Seth Shostakexplains in this engrossing book, it’s entirely possible thatbefore long conclusive evidence will be found.
His informative, entertaining report offers aninsider’s view of what we might realistically expect to discoverlight-years away among the stars. Neither humanoids nor monsters,says Shostak; in fact, biological intelligence is probably just aprecursor to machine beings, enormously advanced artificialsentients whose capabilities and accomplishments may have developedover billions of years and far exceed our own.
