Have you ever wondered - Why were dinosaurs so big?
In 1987 I realized my engineering knowledge of scale effects on structures revealed a startling answer to the mystery of the dinosaurs’ massive size. Dinosaurs could never grow gigantic unless something dramatic had changed. Their bones, muscles and ligaments were too weak.
There was one answer that solved the dinosaurs’ large scale - a reduced gravity. A Reduced Gravity Earth would reduce the weight of all life, so the scale of all life could increase. A reduced gravity explains the dinosaurs' large size.
