Do you have questions about gravity? Have you thought about why nothing REALLY big exists today in nature? Have you ever wondered how 30-foot leather birds were once able to fly? If so, today is your lucky day because Jose Canseco, the world's best Twitter user, has taken to the internet to explain his fascinating theories about gravity, dinosaurs and giant birds.

It all started innocently enough, with a consideration of jam bands.

Those tweets got Canseco thinking about one of science's greatest mysteries.

Thankfully, for all of us, Canseco was good to his word. Just over an hour ago, he launched into an amazing rant about gravity and how it's changed over the years.

Think about it. Jose is making some good points, no? There's at least enough here for our next installment of Hey, Science.
