April 27, 2025What Is Over Baltimore
On TV, a child’s shoes lie in the road—
then a headline: Could be DMS, they say,
statistically shy of truth
but mouthing it.
A sky-seeding gas,
exhaled from the sea’s skin,
born of sun-stress and salt.
I refresh the NASA archive—twice.
Scroll spectra.
Syntax hedges:
tentative, consistent with,
a candidate biosignature—
on Earth.
On Earth,
it lifts from ocean skin—
creature-breath cracked open
by too much sun.
And there,
on a sub-Neptune
called K2-18b,
gravid with remove,
gravity thick enough
to cradle eight Earths
or crush a few denials clean.
And our breathless hope,
the signal wavers.
In the habitable zone,
they say—
but what does that mean
on a burning world?
Because here,
this morning,
another atmosphere flattens.
A man—breathing,
then not,
under police restraint
outside Baltimore.
The footage loops.
No name yet.
No context,
says the statement.
But his breath—
a biosignature,
saturated,
unreturned.
And already, the network news
is rehearsing its vocabulary—
“incident,”
“noncompliance,”
“community trust initiatives.”
And somewhere, a press officer
workshops the phrasing:
“an exothermic misunderstanding”
(their phrase, not mine).
I do not say these are equal.
Only that
I studied a transit light curve
as a city truck sprayed bleach
along the sidewalk
where two unhoused men had slept,
scrubbing biosignatures
from concrete.
I can’t distinguish
dimethyl sulfide
from disulfide
at this resolution—
nor what we call discovery
from what we erase.
Sixteen more hours,
they say.
Let the spectrum deepen.
Let us learn
if something breathes there
or only simulates it.
Not quite a sentence.
Not quite a prayer.
More like breath,
held a second too long
before it forgets
what it was for.
