“The main idea underlying Kragh’s book is the link between varying gravity and the older idea assuming an ‘expansion of the Earth’ in past epochs, discussed since the nineteenth century among geologists and astronomers. … Kragh’s book is a fine example of an inspiring investigation in the history and philosophy of science. I imagine that it will also be of interest to readers with a background in the earth sciences.” (Hubert Goenner, Isis, Vol. 107 (4), December, 2016)“This book is a stimulating reading material because it contains a lot of historical and systematic information in cosmology and geophysics. Moreover, it shows how fantasy can help to overcome disciplinary borderlines … .” (Horst-Heino von Borzeszkowski, zbMATH 1344.83007, 2016)
