The Big Bang Theory: What It Is, Where It Came From, and Why It Works

Synopsis

A lively, accessible look at the Big Bang theory This compelling book describes how the Big Bang theory arose, how it has evolved, and why it is the best theory so far to explain the current state of the universe. In addition to understanding the birth of the cosmos, readers will learn how the theory stands up to challenges and what it fails to explain. Karen Fox provides clear answers to some of the hardest questions including: Why was the Big Bang theory accepted to begin with? Will the Big Bang theory last into the next century or even the next decade? Is the theory at odds with new scientific findings? One of the most well-known theories in modern science, the Big Bang is the most accurate model yet devised in humanity's tireless serach for the ultimate moment of creation. The Big Bang Theory is the first title in a planned series on the major theories of modern science.

Excerpt

In early 1998, two groups of astrophysicists made a startling announcement. The universe, which had always been thought to be expanding, and gradually slowing down, might actually be speeding up. The scientists had been watching supernovas—the explosive death throes of a dying star—at distances greater than had ever been seen before. The speeds and distances of these brilliant fireballs suggested that all of space was swelling up ever faster, accelerating over time.

This information took everything scientists thought they knew about the way the universe was supposed to work and dumped it on its head. Suddenly gravity, the force that was supposed to be holding everything in the universe together and keeping it at a manageable size, wasn't in control. Instead some mysterious energy was actually resisting gravity and counteracting it. The findings, if true, insist that physicists reexamine how they interpret everything from Einstein's relativity theory to how the universe has evolved since the big bang.
