Showing results for "The Five" in Physics

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

In this special themed collection, Melvyn Bragg is joined by guest experts including Simon Schaffer, John Gribbin, Jim Al-Khalili and Sir Martin Rees to discuss 25 of the key laws, principles and problems of physics. Here are examinations of major concepts including plasma, radiation, matter and antimatter and the Second Law of Thermodynamics, as well as discourses on historical theories such as Zeno's paradoxes, the speed of light and relativity.
