we know very little about its core
This means that papers will be published in professional journals with complex models described by elaborate mathematical calculations all leading to erroneous conclusions because they are based on an incorrect initial assumption."Our findings provide a new context into which forthcoming observational data from NASA's MESSENGER spacecraft can be placed, "Li said. "We can now connect the physical state of our innermost planet with the formation and evolution of terrestrial planets in general."
