Earth expansion and how to falsify it.

Not so easy is telling how to falsify this observation. What
geological acid test could be used to FALSIFY it? ....how would you
assess, *GEOLOGICALLY*, if the Earth has got bigger? (Or not?) Really
substantially bigger; doubled in size in the last 10% or so of its
history.

Assuming constant mass, if the Earth has increased in volume, then
there should be voids throughout the interior (sort of like when bread
dough rises); these should be detectable via propagation of seismic
waves.

Unless the earth was denser in the past.

If mass has increased along with volume, then the Earth's gravitational
attraction has also increased over time;

Not necessarily. A long time ago, some (Russell?) recalculated the
entire SI system, basing it on real fundamental values instead of
arbitrary things like meters and the density of water. After he did
that, almost all fundamental constants were close to 1, with two
exceptions: gravitation, which was 10^-40, and the age of the
universe, which was 10^40 (or possibly the other way around, I
don't know).

The conclusion is obvious: as the universe ages, gravity drops, and
the earth (and other bodies) expand.

It's probably complete bull****, but it's an interesting theory.

I'm struggling to understand why, if the mensuration system used is based on
"real fundamental values" the fundamental constants shouldn't be 1.
