We live within a universe so vast
we never will perceive its full extent.
Because there are horizons that are past
the span light can speed in the firmament,
parts of the cosmos will be forever
beyond possible communication.
As fast as light, we’ll still reach them never,
for they have greater acceleration.
We here who are within it can’t exceed
light’s pace in space,
such efforts will be vexed.
Our universe grows faster than light-speed,
so isolates one portion from the next.
We can not know that, there,
physical laws apply or that effect still follows cause.
