Now that we know the age of stars can be told by measuring their speed of rotation, the jig is up for those  celestial impostors who claim to younger than their velocity indicates.

Fess up, Polaris. You’re getting a little long in the tooth!

For some odd reason, it put me in mind of this classic Disney song.

When you time a spinning star
You can know how old it are
Every revolution tells
a tale that’s true.

When it’s whirring like a top
Chances are it’s just a pup.
When the spinning lessens then
it’s more like you.

Stars get old.
Their slowing, up above,
is a precursor of
someday exploding.

Don’t know much, but this I do …
Stars revolve ’til they are through.
When you time a spinning star
you’re spinning too.

How good are you at guessing the age of people and/or things?
