My Bang’s Bigger Than Yours
Astronomers love hydrogen,
And hydrogen alone –
The primal, elemental gas,
That lights up the unknown.
They’re not so keen on helium,
But tolerate it yet –
But hydrogen’s their number one,
As airy as things get !
Astronomers hate lithium,
As dense and overweight,
And ev’rything beyond it is
Too scarce to even rate.
They label them as ‘metals’,
As a grey and seething mass –
Yes, even carbon, even sulphur,
Even chlorine gas.
Astronomers know metaloids
Have properties each shares,
But magnets and electron soups
Are no concern of theirs,
And dabbling in impurities
Requires them to atone –
For ’stronomers love hydrogen,
And hydrogen alone.
