Abstract. In a recent article in this journal, Paolo Sudiro (2014) considered the long history of the expanding Earth theory and its recent descent into what he termed “pseudoscientific belief”. The expanding Earth theory contends that the radius of the Earth was once one-half to two-thirds of its current value, with the Earth's continents forming a continuous sialic cover over the Earth. The theory has had two main variants: slow expansion at about 0.5 mm yr−1 radial increase since the time of Earth's formation and fast expansion at about 5 mm yr−1 since the Triassic. Focusing on Maxlow's model, Sudiro thoroughly addresses the possibly insurmountable difficulties of the fast version, such as an improbably high density and surface gravity prior to 200 Ma. He omits, however, any discussion of the slow expansion model, which has a longer history and far fewer theoretical difficulties. Moreover, recent evidence from space geodesy, gravimetry and seismology indicates that the Earth at present may be slowly expanding at 0.1–0.4 mm yr−1. It is concluded that Sudiro's obituary of the expanding Earth theory as a whole must be considered premature at this time.

目前，来自地球大地测量学，重力测量法和地震学的证据表明地球缓慢扩张- Sudiro（2014）评论“地球膨胀理论及其从科学假设到伪科学信念的转变”

摘要。保罗·苏迪罗（Paolo Sudiro，2014年）在该期刊的最近一篇文章中，探讨了不断扩展的地球理论的悠久历史及其最近沿袭至他所谓的“伪科学信念”。不断扩展的地球理论认为，地球半径曾经是其当前值的一半到三分之二，而地球各大洲在地球上形成了连续的唾液酸覆盖。该理论有两个主要变体：自地球形成以来，在径向增加约0.5 mm yr-1时缓慢扩张，而自三叠纪以来在约5 mm yr-1时快速扩张。Sudiro着眼于Maxlow模型，彻底解决了快速版本可能无法克服的难题，例如200 Ma之前的高密度和表面重力。但是，他忽略了有关慢膨胀模型的任何讨论，历史悠久，理论困难少得多。此外，来自太空大地测量学，重力法和地震学的最新证据表明，目前的地球可能会在0.1–0.4 mm yr-1处缓慢扩张。结论是，此时必须将Sudiro提出的关于整个地球理论扩展的ob告视为不成熟。
