Just my own guess, but I would venture more than a quarter of current diameter, which is a whole lot of circumference! Add the mass impacts that have been added from the solar system debris and we have gained a significant amount of mass since before the dinosaurs and after.

This notion is related to something Tom Van Flanderan was fond of speculating, that there was a large watery world roughly in the orbit of the asteroid field which finally tore apart due to added mass and none flexible crustal make-up. The name for that planet shows up in Sumerian cuneiforms as Tiamat.

BTW, I am convinced that the speed of light has slowed as the Universe has expanded, due to the increase in particles poping in and out of physical existence as the zero point field has increased with the latant stress of spacetime expansion. The zero point field has increased in density as the Universe has expanded, kind of like latent energy when you stretch a rubberband.

Not buying the Earth expansion bit. Speed of light? Who knows. I’ve wondered about the possibility.

You are guessing at things; yet convinced?

OK

“BTW, I am convinced that the speed of light has slowed “

Hasn’t that already been proven with atomic clocks at higher altitudes? Like if you take the slow down and calculate the span of the universe what you see is 14 billion years of time/age, but it is actually 6,000 years old due to slowing of time?
