A dimension is a set of rules for your conversation. It changes what you can do with a message, not who you are talking to. Here is what each world actually does, translated for visitors from planets without typing indicators.
ETH-256 / 01
Earth 256D
A conversation that stays where you left it.
Earth is the familiar chat: you send a message, the other person replies, and the conversation runs in order. It also brings together the surviving record of your travels through other dimensions. Think of it as home, with better documentation of your questionable decisions.
For example
Make a plan in another dimension, then return to Earth to review the surviving messages and journey markers. Many-Worlds branches can be reviewed here; extending them belongs in Many-Worlds.
Come here when
You want an ordinary conversation, a reliable reference, or somewhere to get your bearings.
The catch
Durable history means the transcript remains available. It does not mean Earth resurrects words that have already expired elsewhere.
RDS-257 / 02
Redshift
Five seconds between an impulse and its consequences.
Write normally. When you press Send, your message waits for five seconds before release. During that wait, you can undo it and bring the text back to your draft. Redshift gives your better judgment a small but unusually specific window to arrive.
For example
You send ‘fine, whatever.’ The countdown begins. You hit Undo, restore the draft, and try a sentence that does not require an archaeological team to interpret.
Come here when
You are apologizing, talking through something difficult, or trying to stop your fastest thought becoming your permanent contribution.
The catch
Undo belongs to the waiting period. Once release begins, that option is gone. Redshift adds a pause; it cannot make your words kind for you.
DCY-258 / 03
Decay
The words wait for a witness. Then they fade.
A message stays intact until the other traveler first views it in a visible Decay conversation. That starts a shared fading period. Longer, denser messages get a little more time. When the words are gone, their empty bubbles remain through your current visit, even if you switch chats. Leaving Decay clears those afterimages.
For example
Leave a small confession. It waits to be seen, then fades. The empty bubble says something happened here without continuing to say what. Extremely dramatic behavior for a rectangle.
Come here when
You care about sharing a moment more than keeping a readable transcript of it.
The catch
Fading is a conversation rule, not a promise that every stored copy is erased. The other person can remember, copy, or photograph what they see.
CML-259 / 04
Cumulus
Your thoughts are allowed to stand somewhere else.
Most chats put messages in a straight line. Cumulus arranges them in cloud-like groups instead. Within each group, messages settle into stable positions rather than continually floating around. An arrival, departure, or other conversation event separates one group from the next.
For example
Brainstorm a ridiculous spaceship name. Suggestions gather across the same patch of sky. ‘Tax Evasion II’ has no more authority because it landed higher.
Come here when
You want to brainstorm, improvise, or follow an association without making everything look like a meeting transcript.
The catch
Position is not a ranking or a guarantee that an answer sits beside its question. Bad ideas get the same gravity exemption as good ones.
CNJ-260 / 05
Conjunction
Two honest answers. Neither gets to peek first.
Choose a question theme or ask your own question. Each traveler writes an answer privately and seals it, meaning they commit it for the reveal. The answers appear together only after both people have sealed theirs. Then you talk. In themed rounds, both people choose when to continue; either can skip a question before the reveal.
For example
Ask ‘What does a good weekend look like?’ You answer before seeing their answer. Nobody gets to quietly replace ‘sleep for fourteen hours’ with ‘mountain climbing’ to seem compatible.
Come here when
You want independent answers before discussion, whether you are getting to know someone or making a shared decision.
The catch
A sealed answer may have to wait. Different answers are information, not a cosmic verdict on your relationship.
DLC-261 / 06
Dielectric
They can see the sentence before you are brave enough to send it.
In Dielectric, the other traveler can see your unfinished draft as you type and revise it. Text remains visible while the draft contains words. Clear the whole draft and it disappears; send it and it becomes a message in the transcript. The backstage area has windows.
For example
You type ‘I think I lo’, delete it, then type ‘left my charger.’ The other person may already have seen the first version. Congratulations on your new electrical emergency.
Come here when
You want to think beside someone and both of you are comfortable being seen before the thought is finished.
The catch
Deleting a word cannot make someone unsee it. Enter with trust, especially if your draft usually needs seventeen rehearsals.
SUP-262 / 07
Superposition
Write two possibilities. One becomes the answer.
Prepare two versions of a message. When the other traveler observes it, the app reveals one outcome, consistently shared by everyone. The recipient does not pick between the two drafts. This is a software rule inspired by possibility and observation, not a claim that your phone contains a quantum laboratory.
For example
Write ‘coffee?’ and ‘walk?’ as the two possibilities. One becomes the invitation. The universe has made a decision of manageable importance for once.
Come here when
You want a surprise, a playful invitation, or a low-stakes way to let go of choosing.
The catch
Both versions should be things you are happy to send. Serious consent, emergencies, and medical instructions do not belong in this experiment.
MSK-263 / 08
The Meeseeks Box
Give a shared plan a box to live in.
Create a plan inside the conversation, add steps, and optionally give it a deadline. The box adds check-ins as that deadline approaches. You can track progress together, change the date, finish the plan, or let it go. Its personality comes from the app's plan rules; it is not an AI assistant that does the task for you.
For example
Make ‘actually book the trip’ a shared plan. Add ‘pick dates’ and ‘buy tickets.’ The box remembers the deadline even when you both discover a sudden passion for doing literally anything else.
Come here when
You want a little structure and shared accountability without moving the conversation into a project-management office.
The catch
A reminder is not completed work. Agree on the plan together; an animated box is a poor substitute for consent or a reasonable deadline.
MWF-264 / 09
Many-Worlds Fork
A conversation can take more than one road.
Choose an earlier message and reply from that point to create a new branch. Each branch is its own continuation of the conversation. You can go back and explore another response, but the branches never merge into a single ending. Earth can show the branches later; creating and extending them happens here.
For example
Someone asks ‘Should we move to Mars?’ One branch explores yes. Another explores no. Both keep their own replies. Nobody has to pretend that one answer erased the other.
Come here when
You want to explore alternatives, tell a story with several endings, or see where a different reply might lead.
The catch
Keep track of which branch you are reading. The multiverse is not responsible for you arguing with an answer from the wrong timeline.
ZEN-265 / 10
Zen
You are allowed to stop looking.
Zen is a quiet state you enter by yourself. Messages, activity counts, the composer, and conversation notifications stay out of view until you leave. The other traveler can continue outside. If you have an active tether, it becomes partial while one of you is in Zen: your quiet remains yours, and the other person can keep moving.
For example
You need a break without turning it into a disappearance. Enter Zen. The conversation can wait while you remember that your body is more than a delivery mechanism for thumbs.
Come here when
You need space without being asked to read, count, or reply to anything.
The catch
Quiet does not delete the outside conversation or resolve it for you. Leaving Zen rejoins your online tethered partner's dimension when possible; otherwise you return to Earth.
Other worlds are on the drawing board.
These are upcoming concepts, not available destinations. Names and plans can change. The universe has declined to give us a launch date.
