Do you mean "then" to denote two distinct events in time, or to mean
"therefore"?

I stand corrected: Surface increased therefore volume increased.


Two possible explanations for a
volume increase:

1 - Volume increase is due to density decrease. But it means that
density was much higher in the past which means that gravity was also
much higher. That hypothesis is ruled out by the gigantism of past
fauna/flora.

Also, there's no way for matter to have been 8x as dense.

Though, James Herndon published a paper supporting this hypothesis.

I don't buy it, because I don't think that decompression would occur
over billions years. Moreover, decompression would be unique to Earth
while there are some clues of expansion of other telluric planets (Mars,
Ganymède, Europa...)


2 - Volume increase is due to matter creation. It follows that gravity
changed with a rate depending on the density of created matter.

So how was the matter created?

Don't know. More Science is needed to figure it out.


Considering d the average density and g the gravity at the surface, then
g=Gm/r^2=G.d.V/r^2=(G.d.4pi.r^3)/(3.r^2)=4/3.pi.d.G.r

It follows that if d remained approximatively constant, then the gravity
increased linearly with the radius of the planet.

But you have no independent evidence for that.

Independant from biomechanics? No. But If people were seriously looking
for direct evidences of gravity increase, they may find some.
