"Apollo landings showed that the ring spacing of a plurality of multi-ringed lunar maria precisely fit the pattern for explosion-generated gravity waves in a âliquidâ overlying a rigid substrate, if frozen at times related to their respective explosion energies. Liquidity was attributed to transient melting of an initially hot, plastic layer beneath a rubble crust, owing to pressure relief behind the shock fronts from energetic meteoroid impacts, and freezing to subsequent solidification, upon restoration of isostatic pressure. This interpretation was largely ignored; most geophysicists thought the moon too rigid to sustain gravity waves. Here I show that current acceptance of an initially molten proto-moon with a thin crust credibly supports the âtsunami-likeâ generation of the lunar maria and provides new insight to the moons thermal history.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
