According to the link below the gravitational constant was lower
before the flood, any comments on this ?

The maximum force is roughly 4 to 4 kgf/cm2 cross section of muscle
(300 - 400 kN/m2). This force is body-size independent and is the same
for mouse and elephant muscle.

Calculations bearing on size and power suggested that the maximum
weight that a flying vertebrate can attain is about 50 lb.

Then I come to what Robert T. Bakker has to say about the Texas
Pterosaurs ("The Dinosaur heresies", Zebra Books, pp 290-291:

"Immediately after their paper came out in Science, Wann Langston and
his students were attacked by aeronautical engineers who simply could
not believe that the big Bend dragon had a wingspan of forty feet or
more. Such dimensions broke all the rules of flight engineering; a
creature that large would have broken its arm bones if it tried to
fly... Under this hail of disbelief, Langston and his crew backed off
somewhat. Since the complete wing bones hadn't been discovered, it was
possible to reconstruct the Big Bend Pterodactyl [pterosaur] with
wings much shorter than fifty feet."

The original reconstruction had put wingspan for the pterosaur at over
60'. Bakker goes on to say that he believes the pterosaurs really were
that big and that they simply flew despite our not comprehending how,
i.e. that the problem is ours. He does not give a solution as to what
we're looking at the wrong way.

For a minute, let's put aside the wrongness of the information you saw
online, backspace, and talk about gravity instead. How would we lower
the gravitational constant? The thing about constants is, they're
constant. We're not talking about earth's gravitational field here,
we're talking about the universal gravitational constant. Toying with
it would muck up the universe quite a bit. Why would a perfect, sound-
minded God change the physical laws he established at the universe's
creation? Were they wrong? Is our current gravity detrimental to us?
