Interesting Question

In some ways an odd question to be asked in this forum, but certainly one worth pondering. The real gem here is the places others talke this. I'm not one to pooh pooh amateurs thoughts and questions, because it's not been uncommon in history for a new viewpoint  to derail accepted thinking. There's also the benefit of cross pollenation where a seemingly unrelated field can offer new insights. Anyhow Bill, many thanks.

Interestingly, I DID find the review using the EET search engine!  Gotta love those strange IT folks...

@mhrackin: ...my reference was to the pre-Galilean "consensus" which obviously was not based on any understanding of orbital mechanics.

I know -- I was just being pedantic -- I haven't had enough coffee yet LOL

That is certainly true; however, my reference was to the pre-Galilean "consensus" which obviously was not based on any understanding of orbital mechanics.

@mhrackin: If it were, the sun would be in orbit arounbd the earth.

Well, in a way it is ... they are both orbiting each other, but the sun is so much more massive that the effect of the Earth on it is miniscule. This effect is much more pronounced with regard to the Earth and Moon, which orbit about their barycentre (common centre of mass) that lies about 4600 km from the Earth's centre (about three quarters of the Earth's radius).

@jackxxxx: My guess is that you (presumably as an engineer) never read the classisc Hans Christian Andersen story "The  Emperor's New Clothes."  Otherwise you might be a bit skeptical about "expert" opinion. Anytime I hear the phrase " but everybody knows..." in an informal debate I know then and there that the speaker is WRONG!  Consensus is not truth.  If it were, the sun would be in orbit arounbd the earth.

I think you can believe them for this simple reason: the chances that complete amateurs can find holes in the work of professionals is extremely low. You put together a good argument, but I think the chances of you having thought of something they haven't is very low indeed. You must have a speciality, a day job. What do you think the chances are that they'd spot something you hadn't thought of in one of your projects?
