Gravity they way we are told is a weird thing it takes dark matter and magic particles to make it work , so amazing .
Dino's must have bin ultra light to have existed at those measurements and sizes . Science is so far developed it knows it all . You better pay attention at your local school , they will teach you all ...........

But wait, you could be on to something , it could be all lies to entertain us ;-)

Keep digging friend i think your on to something here .
