PhD, by itself, means nothing to me - anybody with a hard enough ass can get one, especially in the last 20-30 years.
I can’t find anything about this Carlotto guy except claims of his experience - with no mention of institutions or Universities where he has done research or taught.
This appears to be one of his websites:
I’m as great a fan of Art Bell, Coast-to-Coast, etc., as anyone - but I take it as sheer entertainment. I need substantive information about a person’s credentials and achievements to give them any credence beyond their entertainment value.
Carlotto has a PhD in electrical engineering from Carnegie Mellon, serious STEM credentials. There, I did your research for you. Took me 10 seconds.
The plateau the ‘face’ resides on is highly symmetric, i.e., not fractal like natural features. The plateau is in the shape of a shield and there is a straight line that joins the the points of intersection where sides of the shield meet the arc at the top. This is not a matter of pareidolia but discernible features visible at different angles and lighting conditions.
The symmetry is strongly suggestive that this feature is artificial. Not proof of course but suggestive. While you’re at it take a look at the hexagon feature on the south pole of Saturn.
