It's time for science with Jose Canseco

Yesterday, Jose Canseco tweeted the following:

This of course led to great excitement among those of us who wonder what the concept of Science looks like in Jose Canseco's head (just me? yeah, probably just me).  Luckily for us, he did in fact follow through on his promise, and it is fantastic.  Observe:

This is actually something that scientists do debate, since the total mass of the Earth does change a bit over time, thus affecting its gravitational force.  Jose, however, has other reasons for believing this:

Probably something to do with evolution?  You're the expert, Jose, you tell me.

After sharing this intriguing theory about gravity, Jose went on to discuss the planetary physics that caused this gravitational change:

Basically, the Triassic was the Earth's steroid era.

It's thought-provoking, that's for sure.  This concludes today's edition of Thoughts about Gravity, featuring Jose Canseco.
