THE EXPANSION CARD — the LSC-1 face
THE CARD AS TEXT · FOR EYES AND FOR MACHINES

THE EXPANSION CARD · the expanding universe, in numbers

WAKES WHEN someone asks how fast the universe expands, how old it is, or what a redshift means

THE LOOP

  1. recede <distance> · both rates
  2. distance <v | z> · back to distance
  3. age · the universe's age
  4. stretch · a metre of space, growing
  5. say the two rates disagree

NEVER

  • Pick one rate as the truth
  • Use the simple law at high redshift
  • Say bound things like us expand

IT MAKES recede — the recession speed at both rates; distance — the distance; age — the age; stretch — the growth.

THE STANDARD two rates; low redshift only; a flat universe; bound things stay; slow on our scale; distances said two ways.

CITE THIS CARDTHE EXPANSION CARD, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=expansion-card. Punch E240C570238820543CA96CB5. Retrieved 2026-10-11.

What it is.

Works out the expanding universe that Friedmann's equations of 1922 allow and the galaxies' redshifts show: recede gives how fast a galaxy at a distance moves away, at both measured rates, 67.4 and 73.0 km/s per megaparsec, because the early universe and nearby stars still disagree; distance runs it backwards from a speed or a small redshift; age gives the age of a flat universe of matter and dark energy beside the simple 1/H₀; stretch gives how much a length of empty space grows in a time.

It carries a machine that shows its working: recede — the recession speed at both rates; distance — the distance; age — the age; stretch — the growth — 8 checks in its selftest, every command on the record. It will never pick one rate as the truth; never use the simple law at high redshift; never say bound things like us expand. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.

Six laws, written into the card.

They are in the card itself, so the AI follows them.

TWO RATES67.4 from the early universe, 73.0 from nearby stars; both are given, because the disagreement is open.
LOW REDSHIFT ONLYv = H₀d holds near us; past z ≈ 0.1 the card stops rather than mislead.
A FLAT UNIVERSEΩm 0.315 and ΩΛ 0.685 by default, the measured values; --om takes others.
BOUND THINGS STAYAtoms, people, planets and galaxies are held together; only the space between unbound things grows.
SLOW ON OUR SCALEA metre of empty space grows by 7.9 × 10⁻¹⁵ m in an hour.
DISTANCES SAID TWO WAYSMegaparsecs and light-years.

What rides in the card.

In the card’s own voice, with a machine that shows its working.

THE GUIDEreferences/THE-LAWS.md
THE MACHINEexpansion.py · four commandsrecede — the recession speed at both rates; distance — the distance; age — the age; stretch — the growth. Every command prints its working and refuses a bad input; 8 checks in its selftest, every command on the record.

What it does once your AI has it.

  • recede The recession speed at both rates
  • distance The distance
  • age The age
  • stretch The growth
  • On the record 100 Mpc recedes at 6,740 or 7,300 km/s by the two rates; z = 0.02 is about 89 Mpc; the universe is 13.8 billion years old; a metre of empty space grows by 7.9 × 10⁻¹⁵ m in an hour.

What it will never do.

It will never pick one rate as the truth; never use the simple law at high redshift; never say bound things like us expand. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.

No radiation era, no curvature beyond flat, no peculiar velocities: a galaxy's own motion can swamp the expansion nearby. It is an AI reading a text file: it can be wrong, so check what matters against your own records and the source.

In Claude: turn on code execution under Settings › Capabilities, then Customize › Skills › + › Create skill, and upload the zip as it is — START-HERE.md in the box walks you through it, and tells you how to keep the ledger. In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →

Nº 1135 PROPOSED — LAUNCHING SOON

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not medical, legal, tax or financial advice, never the person’s boss, and not a licence to practise. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

One email when it is on sale, from the studio; nothing else, ever.

A TERM, NOT A SUBSCRIPTION: NOTHING RENEWS ITSELF AND NOBODY IS CHARGED AGAIN. WHEN A TERM ENDS THE FILES STAY ON YOUR COMPUTER AND STAY READABLE — FREEZE, NOT LOSS.

QUESTIONS AT THE TABLE

Asked before the wire.

What does it need from me?

Recede <distance> · both rates. It asks first for a distance, a speed or a small redshift; or a length and a time.

Does it send anything anywhere?

No. The machine is a standard-library Python program that runs on your own computer and sends nothing anywhere; the words run wherever an AI reads Markdown. No server, no account, no key.

What is on the record?

The self-test (8/8) and every command run on real example inputs, pasted into WITNESS.md as they printed; the punch on the face is the SHA-256 of SKILL.md, so a downloaded copy can be checked against this room.

Can it be wrong?

Yes — it is an AI reading a text file. No radiation era, no curvature beyond flat, no peculiar velocities: a galaxy's own motion can swamp the expansion nearby.

What will it never do?

It will never pick one rate as the truth; never use the simple law at high redshift; never say bound things like us expand. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.
