While Project Poltergeist was looking for ghosts
They discovered neutrinos, and reckoned
That ten trillion of the little blighters, had been passing
Through their brains, every second
These tiny guys, come in three flavours
Electron, Muon and Tau
They’re ace. They change their taste, in haste
So, what was a Tau one, when it entered your brain
Is probably a Muon one, just leaving Mars…
…. Now
But this identity-switching crisis, is nothing
Compared to their unique ability
To change their mass, as they go past
Or through any, heavenly body
Most of those that got through your thick skull, just now
Came directly from the surface of the Sun
After fighting their way out, from a war in the core
When their journey to, or through, you begun
Yet many of these oddies, that penetrate our bodies
Came from far neutron stars colliding
Or black holes, quasars, pulsars and blazars
After avoiding events on the horizon
We don’t know their mass – yet
But seems less, than a millionth of an electron
They’re nearly too small, to affect anything at all
So, it’s almost impossible to detect ‘em
They don’t interact with visible light, or any waves of electromagnetism
And unless you seek to give em’ a peek, they’ll just hide in a superposition
Yet they can ring hells bells, and mess with stuff in your cells
And while they fly by, other nuclei, they can trigger nuclear fission
Or simply be heroes
On chips, they don’t miss
To flick ones, into zeroes
And that’s nothing, get this…
Unlike almost all other ‘physics’
All light, and the strong force
These tiny weak mites, don’t do left or right
Can’t turn clockwise, or counter
When plotting their course
See, neutrinos have no mirror image
All left-handed, and so it transpires
These ghostly particles have no reflection
Making them the cosmos’ vampires
