A while ago on a Zoom call, a discussion came up about gravity. I posited that gravity here on Earth may have strengthened over the millennia ... and offered the fact that huge ancient dinosaurs do no longer ... but actually could no longer walk the earth ... see: More on Gravity.
... nor that ancient flying reptiles could not get airborne today ... see: Pterosaurs (Updated).
I have also speculated elsewhere that a shortening of actual time itself may have affected our gravity. This is because gravity is a measure of acceleration (distance/time^2) ... and if time gets smaller, acceleration (gravity) gets disproportionately larger.
