Science Saturday: Dark Matter

Dark matter is the stuff unseen by a telescope.
There has to be more matter, scientists hope.
These are mysterious particles indeed.
Better measuring tools we need.
We can only see what is seen by light.
Yet, what is seen doesn't explain its gravitational might.
There has to be more matter, scientists think.
Dark matter appears to be a galactic hoodwink.
But it has to be there, based on observation;
By watching planet, star, and galaxy rotation.
There isn't enough light stuff to prevent stars from flying apart.
Dark Matter plays nice and holds its light friends to the heart.
Dark energy is but a force which scientists are fonder.
Though, there has to be more matter, scientists ponder.
