i've seen this poem re-posted a lot online, and though I haven't read the full collection of poems, i am definitely planning to check out more work by Goldbarth because i think this may just be one of my favorite poems ever. for those who are unfamiliar, here's the entire poem (copied from this website):

Physics says: go to sleep. Of course you’re tired. Every atom in you has been dancing the shimmy in silver shoes nonstop from mitosis to now. Quit tapping your feet. They’ll dance inside themselves without you. Go to sleep.

Geology says: it will be all right. Slow inch by inch America is giving itself to the ocean. Go to sleep. Let darkness lap at your sides. Give darkness an inch. You aren’t alone. All of the continents used to be one body. You aren’t alone. Go to sleep.

Astronomy says: the sun will rise tomorrow, Zoology says: on rainbow-fish and lithe gazelle, Psychology says: but first it has to be night, so Biology says: the body-clocks are stopped all over town and History says: here are the blankets, layer on layer, down and down.

as previously mentioned, I love this poem. it’s definitely one of my personal favorites. It’s a very comforting poem to me, with its quiet rhythm and the verses and language that ring with truth, despite how simple they appear to be.

I love the way this poem frames fatigue and weariness as this inevitable, animal thing by invoking the scientific facts in the discussion of it all. The words carry a deep sense of relief to me. The way I read it, the poem is very soothing in how it emphasizes that exhaustion is natural, and how it says this exhaustion is a consequence of all the forces of the universe, so one should take time to rest without remorse. The weariness is built into the atoms you are made of, the sunlight and stardust you erupted from. Go to sleep, let it go. What’s the point in trying to fight it, to resist, to insist you are the exception? You are not stronger than physics or biology, and it’s okay. The world will still be there when you wake. Go to sleep.

Here, I interpret “go to sleep” as referring to the literal state of being asleep, of course, but also through a more figurative lens. “Sleep” implies resting, healing, being oblivious to the world and all the things about it that cause worry and pain. I like to think that the speaker of the poem is telling the reader to set down their burdens for a while, to let their worries cease for just a little bit. There is time enough for bearing the burdens of the universe, but the cosmos can only extend as far as physics will allow it, and we are merely earth-animals at the end of it all: warm-blooded creatures with red beating hearts and chemical signals that dictate our emotions, nerves and cells and receptors responding to external stimuli as a result of thousands upon thousands of years of continuous evolution. We must rest, and that’s all right; we were not designed to be forever in pain, forever toiling. All motion must come to a stop if there is not enough energy to resist the forces of counter-motion. Go to sleep.

I think the technical construction and style of this poem also lends itself to the soothing feeling it evokes in me. Goldbarth’s language is very simple, almost deceptively so, written in the everyday, mundane language we use to conduct our daily lives. This makes the poem feel intensely familiar, almost intimate, like a casual phone call with a friend rather than an elevated oratory performance, of the kind you’d expect to see as part of an elaborate theatrical production. It feels comforting the way a postcard on the fridge—colorful but cheap, faded by the sun, unremarkable to everyone except the owner who has kept it there for 10 years—might be comforting.

Physics says

The physics section emphasizes how we are made of atoms, these bits of matter that vibrate in constant, imperceptible motion. Where there is life, there is motion; the poem says as much with these verses:

Every atom in you has been dancing the shimmy in silver shoes nonstop from mitosis to now.

“Mitosis”—the process by which cells replicate to create new cells, to grow the body, to repair damaged muscle and tissue—i.e., the cellular process we all started from. It’s such a fun set of verses, as sprightly as the atoms and metaphorical dance steps that form the basis of the subject matter. The emphasis is firmly fixed on the movement—of the cells and atoms you are made of, and of the syllables as they hop and skip right off the tongue. Those s sounds come fast, playful, all breath-breath-breath as they fall out of the mouth without giving the reader time for a pause. And “shimmy in silver shoes”, along with “tapping your feet” and “They’ll dance inside themselves without you”, evoke the same feeling through visual image and physical sensation.

I really enjoy the way this stanza takes these microscopic cellular movements and draws them large, relating them to dancing and feet tapping. I understand the vibration of atomic particles and cellular division via mitosis on an abstract, intellectual level, but I feel the larger physical sensations of tapping my feet, drumming my fingers, and flashing quicksilver dance steps in my own limbs. Goldbarth draws a connection between these two distinct forms of motion, emphasizing both the frenetic energy of flesh-and-blood existence and how that existence means we must take time to rest and allow our cells to repair and replenish themselves.

Geology says

In a fun little parallel to the small-to-large arc contained within the previous stanza, the progression to the geology stanza immediately takes us from the scale of atoms to continents. Here, the speaker really hammers in the vastness of the universe, and paradoxically, it makes me feel small in a way that is deeply comforting. It reminds me that my existence is just a tiny speck in the universe, and no matter what I do, the world will go no long past I’m gone. The poem seems to say: don’t worry so much. There’s no rush; the earth moves too slowly for one, five, ten years to make a difference; you might as well take it slow, too. Enjoy the time you have.

I love the repetition of “you aren’t alone”. I think being lonely at various stages of my life has definitely been an influence as to why I’m fascinated by the natural world and the “cycle of life”, so to speak; the knowledge that all my cells and atoms came from the earth and will go back to the earth has always made me feel part of something larger than myself in a way that brought me comfort and reassurance. I like how the geology stanza evokes that feeling in describing Pangaea and the slow, constant shift and subduction of tectonic plates.

Finally, I really enjoy the line “Let darkness / lap at your sides. Give darkness an inch.” Darkness compared to the lapping of waves at the shore somehow transforms it away from a foreboding, consuming force, and instead one of peace. I’m reminded of this description from Langston Hughes’s poem “After Many Springs”: "[...] the night is a vast softness"

Astronomy and Zoology say

The poem begins its third and final stanza with a sunrise—how lovely! I love the intention behind including "rainbow-fish" and "lithe gazelle". Both animals are known for jumping/leaping in graceful arcs, mirroring the path of the sun across the sky, so it’s very easy to imagine the sun on their backs (all that glittering, shimmering dawn-brightness) as they launch themselves upwards.

Psychology and Biology say

I'm honestly not too sure what this line refers to, in how it relates back to psychology as a scientific field (biology seems more straightforward, "body-clocks" being a layman's interpretation of circadian rhythm and all that). would love to hear others' interpretations!

History says

I adore the way the poem ends. It opens with the frantic, constant, minuscule movement of atoms, then expands into the wide edges of continents, then peers out of the darkness with promises of rising sun. But remember: it’s night, it is time to sleep. The poem returns to that idea with a definitive note in its final verses.

I like the double (maybe triple?) meanings of the last verse a lot. I interpret it as something like- here are the blankets, layered up for you: go to sleep. Down and down through the beginning of time, down and down through layers of the past, down and down through stone and earth, until you hit the molten core of the planet: this is what creatures like you have done for all of history. Go to sleep.

I'm definitely not a poetry expert or anything; I was doubting posting this at all, because I really am not qualified to speak authoritatively on poetry and haven't really had much chance to study it as a form of art and literature. but, I would really love to hear how other people read this poem, and if you have a favorite part and/or if you see any other fun scientific connections to be drawn!
