Hubble Bubble

Doesn’t it seem sometimes
As if the world’s a child
Given the assignment

To construct a cosmos
Given infinite time
To change but circumscribed,

Never-changing volume
In which to do it all?
Indefinite time-out

In a conjuror’s cell
Where anything can be
Called up, but only if

Something of exactly
The same dimensions
Vanishes forever

From the constricted room—
We know that’s not how most
Models of the cosmos

Render it, but it would
Explain the way things go.
Only the changes grow.
