The discoveries of modern physics are so astounding and counterintuitive that they almost defy belief. Yet ample evidence shows that such baffling theories as quantum mechanics and general relativity must be correct, if only because some of today’s key technologies wouldn’t work without them. Indeed, there is no end to the bizarre findings of physics, for example:

The Unobservable Universe. What lies beyond the most distant bounds of the observable universe? Since light from that region can never reach us, we should never know. Yet scientists have deduced from the subtle signature of the Big Bang that the entire universe must be at least 500 times wider than what we can see.
When faced with such claims, it’s only natural to ask: How can anyone possibly know this? But as scientists have done since the earliest days of their profession, they evaluate the evidence, frame hypotheses, conduct experiments, and weed good ideas from bad as they close in on what must be the truth.

In a riveting course designed to give non-scientists the matchless experience of scientific discovery and deep understanding, The Evidence for Modern Physics: How We Know What We Know takes you through the most remarkable insights of contemporary physics, showing why physicists believe what they do.

Space and Time Transformed. In the 1880s, measurements of the speed of light showed it was always the same, regardless of the speed of the source. Two decades later, Albert Einstein postulated that the speed of light is constant; it is space and time that stretch and contract. He developed this idea into his theory of relativity.
The major methods devised to pinpoint thousands of planets orbiting stars in our neighborhood of the Milky Way Galaxy;
The first detection of gravitational waves, generated by colliding black holes in a distant galaxy-an event now seen multiple times;
The enigma of dark matter, which is five times more prevalent than ordinary matter, although no one yet knows what it is;
The hypothesized force called dark energy that is causing the universe to expand at an accelerating rate; and
The incredible theory of cosmic inflation, which accounts for largescale properties of the universe, but is still awaiting proof.
In this way, The Evidence for Modern Physics teaches you how physicists think: abstractly; intuitively; critically; and always answering to data, data, data. The history of science is littered with discarded ideas that are beautiful and ingenious, but also wrong. Even the best physicists go down blind alleys; Einstein is a prominent example. But if they keep at it, they usually find their way into a corridor that leads somewhere interesting, and if they are lucky, to the solution of a long-standing puzzle.
