Now aliens, they might be reeeeeeeeeally big. Big. Big. Big.
Aliens could be huge, says scientist
EXCERPT...
University of Barcelona cosmologist Fergus Simpson has been thinking deeply about alien size. He recently published a paper entitled "The Nature of Inhabited Planets And Their Inhabitants."
He relies on a mathematical model that says other planets conserve energy just like we do. "Throughout the animal kingdom, species which are physically larger invariably possess a lower population density, possibly due to their enhanced energy demands," he says.
Bigger beings consume more and release more energy than do smaller beings.
Earth, he says, "constitutes a simple random sample amongst inhabited planets." We have more smaller beings than larger ones. He doesn't believe, however, that Earth is a fair sample. Instead, he says that "most inhabited planets are likely to be closer in size to Mars than the Earth."
If that is true, then "since population density is widely observed to decline with increasing body mass, we conclude that most intelligent species are expected to exceed 300kg." Yes, that would be 650 pounds.

This alien has a big body, but a small head.

That's more like my self-portrait, though, dinosaur dat I am.

I agree Pluto and Ceres are full planets, but I think it's all going to seem pretty irrelevant soon

We've always called the Brontosaurus a Brontosaurus and it's a pain in the ass

I agree Pluto should be re-recognized as a planet, but I'm not so sure about the brontosaurus.

Better to wonder why people who believe the earth is 6000 years old want to kill for a fossil fuel.

That's because they define themselves by their status and that includes their possessions.

Brontosaurus just sounds better. Glad Bronte got a restoration of her respectability.
