Cosmic Background Calibration Office Shirt | Cosmology Tee

A bureaucratic change request concerning a microscopic adjustment with galaxy-sized consequences.

BEHIND THE DESIGN
The early universe was almost uniform.

Almost.

The cosmic microwave background is the cooled afterglow of the early universe. Today its average temperature is about 2.725 kelvin with tiny variations on the scale of roughly one part in one hundred thousand.

About 0.001%.

Those variations preserve the imprint of small differences in the early distribution of matter. Gravity amplified that unevenness. Slightly denser regions gathered more matter and over immense stretches of time those differences helped give rise to galaxies and the large-scale structure of the universe.

A very small difference.

A very long reach.

That relationship became the starting point for Cosmic Background Calibration Office.

We imagined the beginnings of cosmic structure passing through an ordinary office procedure. A request from the Quantum Fluctuations Division. A calibration dial. A baseline temperature. An approval stamp.

The requested adjustment barely registers.

The paperwork looks routine.

EXPECTED IMPACT: NEGLIGIBLE.

ACTUAL IMPACT: GALAXIES.

The numbers belong to cosmology.

The administrative arrangements are ours.

We chose this idea because it asks us to reconsider what counts as significant. Something almost lost in the decimal places can leave its mark across the sky.

Sometimes the smallest detail is where the whole story begins.

Beauty. Discovery. Depth.

THE EDITION
Original Edition. The approved primary graphic is printed on the front.

THE SHIRT
Unisex T-shirt
• Available in Crew neck and V-neck
• Black and Navy

NECKLINE NOTE
“Crew Edition” describes the artwork placement, not the collar. Both Original and Crew Editions can be ordered with either a crew neck or V-neck.

PRINTING AND FULFILLMENT
Proof & Particle creates and verifies the original artwork. Printful, our disclosed production partner, prints, packages, and ships each shirt only after it is ordered. Slight variations can occur because ink interacts with natural fabric fibers.

CARE
Wash cold, inside out, with similar colors. Tumble dry low. Do not bleach, dry clean, or iron directly over the print.

DESIGN TRANSPARENCY
Generative tools supported early concept exploration and blank-garment mockups. Every final word, equation, symbol, and technical diagram is independently prepared and checked by Proof & Particle.

MADE TO ORDER
Please consult the size chart for the selected neckline before purchasing. If an item arrives damaged, misprinted, or incorrect, contact us through Etsy with photographs so we can make it right.

FABRIC WEIGHT & SHRINKAGE
Our Bella + Canvas cotton tees are soft and lightweight (4.2 oz/yd² / 142 g/m²), not heavyweight shirts. Pre-shrunk does not mean shrink-proof. Warm or hot washing and high dryer heat can cause additional shrinkage and affect the print. Follow the garment label: wash cold, inside out, on a gentle cycle with mild detergent and similar colors. Avoid bleach and fabric softener. Air dry or tumble dry low; do not iron the print or dry clean.
