Talk:Innermost inner core

First review
I've posted this message around one week ago, but in a different talk section! Hi, this is Alejandro Cabrales. I'm reviewing your article. Despite being still short, I see it's well structured. The lead is concise. The Dynamics section talks about an anisotropic sphere inside the inner core. It is necessary to explain the nature of such anisotropy (in propagation velocity, radial, etc.). Likewise, you can create sections about the two hypotheses of the innermost inner core (IIC) radius. The implications section suggests the interesting possibility of a different iron phase, and need more elaboration. In the figure I'd mention which of the phases illustrated would correspond to the IIC. The section of other explanations is good idea, reflecting what you mentioned in the lead, that the IIC theory is not generally embraced. Finally, I see that your references are solid.AlexInMetal (talk) 20:29, 24 February 2019 (UTC)

Second review
Hi Charlie. I see better structure in your article, yet I feel you need to expand more the sections. My article is not the best of the examples, yet what I did was explaining different hypotheses regarding my topic, avoiding equations. For instance, you may elaborate more about the discrepancies in the traveltime models that led to propose the IIC theory. How has the people estimated the radius of the IIC? I also wonder if there might be (predicted) consequences in the magnetic field (Not 100% sure that these questions have answers in the available papers!). Finally, you may elaborate about two or three alternative explanations. These are my comments, hope they are useful! AlexInMetal (talk) 07:46, 10 March 2019 (UTC)
