Vast problem still obscure

Most of the mass of the universe

may be contained in dark matter.

No one knows what that may be.

Astronomers say we could be

dealing with planetary objects

unable to produce luminosity;

some believe we are looking

at black holes or other things

formed when stars are born or die.

(For physicists, the hear

of dark matter lies in axions,

strings, magnetic monopoles.)

If related to stars, dark matter

presumably will be found where

stars are. If indeed exotic,

it won’t react with matter

as we know it nor, probably,

with itself; and it surely

will, in any case,

have nothing at all to

do with everyday matter.
