In the March 2019 issue of the Rendiconti Online of the SGI, a geologist continued his attack on the theory of terrestrial expansion (Sudiro, 2019), this time focusing on the implications that paleomagnetic data, particularly the paleopoles, have as evidence for the expanding Earth concept. An initial more general publication on the subject by the same author appeared in the EGU History of the Earth Sciences journal in 2014 (Sudiro, 2014). The present paper demonstrates the inadequacy of many of the criticisms formulated in the above publications, making it clear that the Expanding Earth is not an out-dated idea from the historical-scientific contingencies of the past, but instead a scientific concept that is very much alive and with very interesting future prospects. The evidential value of the paleopole data and catalogues is specifically defended here, together with the TPW and its link to the opening of the Pacific Ocean. The numerous lines of research that have emerged on the basis of EE are briefly described in a non-exhaustive review. The failure to recognise the expansion of celestial bodies as a phenomenon could be a contributing factor to the current state of crisis in Physics and Cosmology.
