When it comes to science, the evidence should rule the day. Roger I. Parker II puts myths revolving around physics to the test in the third edition of Myth Busting Physics. Get answers to questions such as: Is time a fourth dimension? Can quantum fluctuations in a vacuum exist? Do photons have mass? Is there anything outside the observable universe? Can anything be colder than absolute zero? Parker also examines why some physicists believe they can get something from nothing and how the Pauli Exclusion Principle provides a way to either prevent time travel or to make it very difficult. Other topics include the Casimir Effect, the large-scale structure of our universe, the relationship between thermal radiation (light) and the warping of space (gravity), why temperature fluctuations and not mass determine the fate of the universe, and our concept of the universe. Join the author as he takes a closer look at the universe to show what is true-and what we've gotten all wrong.
