Neutrinos

Through the night,the dark wind blows,
And it's replete with wispy neutrinos.

Silently passing through everything,
Is it a wave,particle or a string?

Obviously all,
Because it's a fermion.

Having different forms,
In beta decay it is formed.

It is a form of matter,
But a candidate for dark matter.

No mass detectable,but energy abundant,
In such numbers as to become redundant.

Such particles we barely detect,
But in numbers so large you can't deny an effect.

When comes a time we understand and harness their power,
The universe will open to us like a flower.
