No, Jose Canseco, 'ancient gravity' did not create the dinosaursGeorge Dvorsky2/26/13 5:40pmFiled to: DebunkeryPaleontologyDinosaursGravityPhysicsJose CansecoScienceScitweet81EditPromoteShare to KinjaToggle Conversation toolsGo to permalink Early last week, baseball legend Jose Canseco explained gravity to the Internet. He tweeted that "ancient gravity was much weaker" during the time of the dinosaurs, which allowed for their massive and nimble size. Needless to say, Canseco was ridiculed for his comments, but very few people actually took the time to explain why he was wrong. Even Bill Nye failed in this regard. Thankfully, some writers have come to the rescue.
