It is commonly assumed that if the Sun suddenly turned into a black
hole, it would suck Earth and the rest of the planets into oblivion.
Yet, as prominent author and astrophysicist Jeffrey Bennett points out,
black holes don't suck. With that simple idea in mind, Bennett begins an
entertaining introduction to Einstein's theories of relativity,
describing the amazing phenomena readers would actually experience if
they took a trip to a black hole.
The theory of relativity reveals the speed of light as the cosmic speed
limit, the mind-bending ideas of time dilation and curvature of
spacetime, and what may be the most famous equation in history: E = mc2.
Indeed, the theory of relativity shapes much of our modern understanding
of the universe. It is not "just a theory"--every major prediction of
relativity has been tested to exquisite precision, and its practical
applications include the Global Positioning System (GPS). Amply
illustrated and written in clear, accessible prose, Bennett's book
proves anyone can grasp the basics of Einstein's ideas. His intuitive,
nonmathematical approach gives a wide audience its first real taste of
how relativity works and why it is so important to science and the way
we view ourselves as human beings.
