RE: Gravity and The Dinosaur Paradox
Fascinating subject. I'm not into physics but grasp the questioning of how could the large Dinosaur survive Earth's present gravity. I always thought the higher oxygen made everything bigger. But there had to be other differences than today that we don't know of.
For our plants today, more co2 makes for larger more vigorous plants...so how in the heck didn't a more oxygenated atmosphere grow maga-flora? I love the freedom to question, it is almost as much fun as flying <3
Unless there was more co2 in the air back then. Wikipedia .. CO2 today is 407 ppm (parts per million) ... Cmbrian period 500 million yrs ago was 7,000 ppm That to me is the answer. And the reason Oxygen was 35% was due to the tremendous amount of plant life giving off 02.
