A Few Remarks on "The Length of Day: A Cosmological Perspective"

Authors: V. Christianto, Matti Pitkänen, Florentin Smarandache

An interesting hypothesis concerning the varying length of day has been formulated in this edition, proposed by A.I. Arbab, based on a proposition of varying gravitational constant, G. The main ideas are pointed out, and alternative frameworks are also discussed in particular with respect to the present common beliefs in astrophysics. Further observation is of course recommended in order to refute or verify this proposition.
