So if the earth and the moon had their current size, but equal weight (or density not sure how to define), would we weigh the same. As it stands now, you can bounce around on the moon. I am curious as it relates to dinosaurs roaming the earth. Something must have happened (cosmically) to the earth that allowed things to get that large. I dont think they just evolved that way. I often wonder if the earths weight has changed over time (weight of meteors over millions of years) effecting the gravity on the earths surface, phasing out larger creatures. But I dont even know if it's the earths actual size or weight (or maybe even spin) that holds us to the surface. Thanks!!!
