Re: An expanding earth experiment

As I understand it, no proposal for the expanding earth hypothesis

- if, for instance, you suppose that the material inside the earth
somehow expands as it cools, like water into ice.

Of course the only reason for supposing that, is if you're groping for
a reason to believe that the earth could be expanding.

I argue that this point alone potentially falsifies the notion of an
expanding Earth unless they can propose a falsifiable mechanism to add
mass. A LOT of mass. Probably on the order of millions of tons a day
as an intuitive guesstimate.

According to http://news.bbc.co.uk/1/hi/sci/tech/89397.stm
("Space dust did for dinosaurs" - 1998), which now looks odd - to me
anyhow - "the Earth's eccentric orbit...changes slightly from a circle
to oval every 100,000 years", huh?? - we get about 30,000 metric tonnes
of dust in a year - estimate, I suppose. I mean, no one collects it
all up and weighs it.

I'm not sure if this means we're still gaining net mass. We lose some
atmosphere all the time, I believe; isn't that something else that the
dinosaurs had more of than we do?
