The Biggest Question in the Universe

Propose in space

Some love is too big for this planet. Send your proposal as a real radio signal to the stars — then show them it's already been traveling at the speed of light.

Why a space transmission makes an unforgettable proposal

Every proposal has the same basic structure: the question, the ring, the answer. What makes a proposal memorable — what becomes the story people tell for the rest of their lives — is the unexpected detail that makes it completely, impossibly theirs.

A real radio signal carrying your proposal, aimed at a star, traveling at the speed of light — that's the detail. Not just a gesture, not just a symbol, but a physical event: your words, encoded in binary, broadcast from an antenna, passing the Moon within 1.3 seconds, past Mars within minutes, moving outward through interstellar space forever.

Before you even ask the question, your proposal is already in space.

Three ways to use a transmission in your proposal

Before: the reveal — Compose the message before the proposal. When the transmission confirms, you have proof that your words are already in space. During the proposal, you reveal the framed certificate or pull up the Signal Tracker. They say yes to a question that was already sent to the stars.

During: the moment — Some couples send the transmission immediately after the yes. Open the Cosmic Echo app together, write the message in that exact moment — "We said yes. We don't know what comes next. We know we want to figure it out together." — and hit send. The Signal Tracker activates minutes later. Your engagement is recorded in the universe.

After: the keepsake — Send the message as a commemoration of the engagement, not during it. Use the message to describe the proposal moment itself — where you were, what you said, how it felt. The framed certificate becomes a record of the night, hanging in your home as a permanent reminder.

What to write in your proposal transmission

The message is up to 100 words — enough for everything that matters, not so much that you overthink it. Here are some approaches:

The direct proposal: "From [your name] to [their name]. I have spent [X] years trying to figure out how to say this. I've decided I can't improve on simple. Will you marry me? This message will travel through the universe for millions of years. I hope your answer goes with it."

The story: "We met [where/when]. I knew [moment you knew]. You have made [what they've made of your life]. I want to spend the rest of mine finding out what comes next. I am asking you to come with me. For all of it. The answer I'm hoping for is already on its way to the stars."

The post-yes commemoration: "On [date], at [place], I asked [name] to marry me. She said yes. This message was sent to [star] to mark the beginning of everything."

Choosing the destination star for your proposal

The star you choose becomes part of your engagement story — something you can point to on clear nights for the rest of your lives.

Vega — One of the brightest stars in the summer sky, 25 light-years away in Lyra. Visible with the naked eye, meaningful in astronomy, and the destination in Carl Sagan's Contact — about communication across impossible distances. Deeply romantic.

Alpha Centauri — The nearest star system at 4.37 light-years. The closest thing to a neighbor. A symbol of the next chapter being right there — just out of reach but absolutely reachable.

Polaris — The North Star, 433 light-years away. The star that has guided travelers home for all of human history. For a proposal that says: wherever we go, I will find my way back to you.

Deep Space — No specific target. Your love radiates outward forever, in all directions, addressed to nothing and everything. The most open and honest destination: we don't know what's out there, and we don't care. We're going anyway.

The framed certificate as a proposal keepsake

The framed Transmission Certificate ($89) is museum-quality — a dark, minimal, beautifully formatted document containing:

• Your proposal message, exactly as transmitted
• Sender and recipient names
• Destination star and distance in light-years
• Transmission date and time
• Station coordinates and signal frequency (1420 MHz)
• A unique SHA-256 cryptographic hash for permanent verification

It goes on the wall of your first home together. Or the office. Or anywhere that matters. It's the document of the most important question you'll ever ask — and proof that you sent it to the stars before you even knew the answer.

Frequently Asked Questions

Everything you need to know

The most popular approach: compose your message before the proposal, then reveal the framed certificate or Signal Tracker during the moment — showing the proposal is already traveling through space. Others send immediately after the yes, marking the exact moment. Some use it afterward as a keepsake.

Yes. The message is entirely yours — up to 100 words. Write your question, your feelings, your history together. It is encoded in binary and transmitted exactly as written, becoming a permanent, verifiable record of the moment.

The framed certificate ($89) is most popular for proposals — museum-quality, ready to hang in your first home. The printed certificate ($49) is also beautiful. The digital certificate ($19) works perfectly if you want to present it on screen as part of the proposal itself.

About 6 hours after purchase. If you want the transmission confirmed before the proposal, order at least 8 hours in advance. You receive an email when the signal leaves Earth — that's your confirmation that the proposal is already in space.

Yes. You choose whether your message is public (visible on the Signal Explorer) or completely private. Most proposal messages are private — only you and your partner can see the content and use the Signal Tracker.

Transmissions currently launch approximately 6 hours after purchase. If you need it transmitted on a specific date (e.g., the anniversary of when you met), order early and consider the timing. Contact us if you have specific scheduling needs.
