For more than half a century the theory of continental drift was widely derided. Innovators developing the radical theory were labelled as unscientific by well-known science authorities. But then, in the space of a few years, virtually all opposition dramatically collapsed. Continental drift was transformed into plate tectonics and became widely acknowledged as one of the most profound scientific revolutions of the twentieth century.
Yet a number of science innovators who had been closely involved with creating this new theory of the Earth continued to research an even more radical theory. The researchers saw evidence that the new plate tectonics theory was incomplete, arguing that continental drift was caused by the Earth expanding in size.
These science innovators give us a unique insight into their experiences. They relate their personal histories of Earth expansion in 14 original essays.
