Generally, the scientific community finds no evidence to support the expansion of the Earth theory, and uses the following arguments to dismiss it:

* Measurements with modern high-precision geodetic techniques show that the Earth is not currently increasing in size to within a measurement accuracy of 0.2 mm·y−1.[13] Furthermore, the motions of tectonic plates and subduction zones measured by a large range of geological, geodetic and geophysical techniques supports plate tectonics.[14][15][16]

* Mass accretion on a scale required to change the Earth's radius is contradicted by the current accretion rate of the Earth, and by the Earth's average internal temperature: any accretion releases a lot of energy, which would warm the planet's interior. Expanding Earth models based on thermal expansion contradict most modern principles from rheology, and fail to provide an acceptable explanation for the proposed melting and phase transitions.

* Paleomagnetic data has been used to calculate that the radius of the Earth 400 million years ago was 102 ± 2.8% of today's radius.[17][18]

* Examinations of data from the Paleozoic and Earth's moment of inertia suggest that there has been no significant change of earth's radius in the last 620 million years.[19]

плохие, значит. учебники. Там тоже не говорили. что это верно, но упоминали без крика в голосе - мол, мы так не считаем. но есть такая гипотеза. А, может, и нет.
