Sense Sonnet - Chiller

Looking Black Hole

Astronomers on Earth refine
The ways and means to calculate
The infinite light years that shine
To us at a forever rate.
Monster black holes lurking out there,
Provide new points of measurement,
At the cores of galaxies where
Mind over matter may present.
So sinister sounds a black hole.
Does one lurk in the Milky Way,
Used by aliens for the goal
Of seeing us in cosmic ray?

The universe is growing, so,
Compared to what - anyone know?
