Einstein's bridge

the long version

A startling and breathtakingly believable tale of big science and the near future, and of a terrifying threat to humankind's very existence that waits at the farthest reaches of the cosmos.In a newborn 21st century, the genius minds at the Superconducting Super Collider (SSC) project in Texas have discovered tunnels through space-time that connect our planet with hitherto unimagined alternate universes. At long last, humanity's cherished dream of alien contact has been achieved. But at what cost? For an ancient, hostile, life-annihilating entity has now locked into a faint, persisting signal emanating from a distant and uncommonly fertile feeding ground called Earth. "Compelling and richly imaginative". -- Greg Bear "Wonderful...a great read...combines the grandiose vision of an Arthur C. Clarke with the good old-fashioned nasty aliens of a Jack Williamson or Larry Niven". -- Starlog "A fast-paced, insider's view of how high energy physics actually works...I couldn't put it down". -- Gregory Benford "A lot of marvelous speculation about the possibilities out at the cutting edge, as well as a suspenseful story". -- Poul Anderson "Cramer splendidly demonstrates just how fascinating and mind-boggling real science can be". -- Kirkus Reviews [source GoodReads]
