Firstly respect is obviously due, for a new idea about stonehenge and the balls to follow it up so enthusiastically. the model looks very tempting, a full scale replica made from all the right materials and with the same building techniques would be even more so.
But when you say the idea wont go away, why wont it ?
what is being done to get the tests performed, EH and the arceoes would have to both want it and they're not specially well known for accepting another persons point of view especially about their beloved stonehenge
It would be good to know something specific about the place but i'm afraid that nothing will ever come of this brilliant idea, and then end up as another theory about prehistory.
But also people like stonehenge the way it is... mysterious. Wouldn't something as seemingly mundane as a grannary be a tad dull.
Which would you visit a suspected alien landing pad or dusty miller's place

Something similar yet unrelated is this. In Axum Ethiopia there is a church dedicated to St Mary inside is the Ark of the covenent rediculous isnt it?
And yet all the information says it to be so, but of coure no-ones aloud inside and it cant be proved one way or t'other.
It's similar because no matter how fantastic the theory if everybody isn't on your side it will fall through at some point and end up as a footnote at the end of a chapter in someones book.
