A libertarian blog says Einstein Was Wrong, and has a list that rivals Conservapedia's Counterexamples to Relativity.
Some of these are genuine anomalies that have puzzled scientists. Others are paradoxes and misunderstandings that are explained in standard textbooks.
As I explain in my book, Einstein was wrong about a lot of things, but we have no substitute for relativity. It is essential to modern physics. Relativity is usually described as strange, but the world would be much stranger without it.
