Part 5/10:
The Dinosaurs: Weighty Issues
One fascinating aspect discussed was the size and weight of dinosaurs relative to today's gravity. As Peter pointed out, if dinosaurs lived today with the same mass, their joints would likely be unable to support their weight properly. This raised the possibility that gravity must have been significantly weaker during the Mesozoic Era.
Through discussions of dinosaur bone strength and environmental conditions, Peter proposed calculations suggesting that if the force of gravity were less than today, it could account for larger-bodied creatures. This point led the conversation to investigate what these changes in gravity might indicate about the Earth's mass over time.
