Hawking radiation is often intuitively visualized as particles that have tunneled across the horizon. Yet, at first sight, it is not apparent where the barrier is. Here I show that the barrier depends on the tunneling particle itself. The key is to implement energy conservation, so that the black hole contracts during the process of radiation. A direct consequence is that the radiation spectrum...

While a large number of so called metadiscoursal resour...

Galileo Galilei (1564–1642) is a pivotal figure in the development of Western science. Albert Einstein called him “the father of modern physics—indeed, of modern science altogether” [5]. More recently, Stephen Hawking wrote: “Galileo, perhaps more than any other single person, was responsible for the birth of modern science” [13]. Galileo’s trial and condemnation by the Inquisition in 1633 have...
