Jose Canseco baffled his nearly half a million Twitter followers Monday, by explaining his very, ah, original views on gravity and astronomy.

"Ancient gravity was much weaker," Canseco explains in one tweet. Adding shortly after, "You ever wonder why nothing REALLY big exists today in nature?"

And while his Twitter followers were pondering how the earth's oceans, mountains and glaciers are somehow not large enough for Canseco, the former Major League slugger, who now plays for United League team the Rio Grande Valley WhiteWings went on to explain that when he wrote nature he meant the beasts of the world.

He wonders why dinosaurs aren't still walking around.

"Elephants today eight tons supersaurs two hundred tons, a totally different world. Why?" Canseco asked in a tweet. Adding in others, "Animal tissue of muscles and ligaments could not support huge dinosaurs even standing up or pump blood up 60 foot necks...gravity had to be weaker to make dinosaurs nimble."

While Canseco is correct that elephants have evolved into being smaller than their prehistoric predecessors, it is difficult to make the leap in logic (particularly without any additional proof) that elephant size has changed because of gravity.

"They were too big to sustain themselves on this dying planet that's why they were punished," explained Leigh Cardholder matter-of-factly in a reply to Canseco's tweet.

But, as Canseco explains in another series of tweets, it all had to do with the land being further from the earth's core.

"My theory is the core of the planet shifted when single continent formed to keep us in a balanced spin," Canseco wrote, adding in another tweet. "The land was farther away from the core and had much less gravity so bigness could develop and dominate."

Monday's Canseco tweets have been retweeted hundreds of time. And although many of the responses to the former Oakland Athletics outfielder, "theories" were supportive, Maia Weinstock explains that Canseco's crazy ideas about gravity are not a theory.

"You mean your hypothesis," Weinstock tweeted. "There's a big difference; a scientific theory requires lots of supporting evidence."

Canseco is the first player to ever join the so-called 40-40 Club, for hitting 40 or more home runs and stealing 40 or more bases in a season. He later admitted to using performance-enhancing drugs throughout his major league career.

At the end of his rant, Canseco explained that his theory could be flawed:

"I may not be 100% right but think about it," he tweeted. "How else could 30 foot leather birds fly?"
