A time capsule that never stops moving
Traditional time capsules sit in the ground and wait. They're sealed in metal boxes, buried under cornerstones, and forgotten. Many are lost entirely — corroded, bulldozed, or simply never dug up. The International Time Capsule Society estimates that roughly 80% of all time capsules are lost before their intended opening date.
A cosmic time capsule is fundamentally different. It's a radio signal that moves at 299,792 km per second, racing outward from Earth in the direction of your chosen star. In one year it travels 9.46 trillion kilometers — one light-year. In a million years it will have crossed a significant portion of our galaxy. It doesn't degrade, it doesn't rust, it doesn't get forgotten in someone's basement.
The electromagnetic energy spreads thinner over distance (inverse-square law), but it never reaches zero. The wavefront continues expanding outward as a sphere at the speed of light. In the most literal sense possible, your message becomes a permanent part of the physical universe.

Preserve a moment forever
Birthdays. Weddings. The birth of a child. The loss of someone you loved. A thought you had on a Tuesday afternoon that felt important. The day you got the diagnosis, the day you beat it, the day you realized everything would be okay.
A cosmic time capsule preserves that moment as energy traveling through space. The words themselves become electromagnetic waves — real, physical, measurable energy carrying your thoughts outward indefinitely. It's not a backup on a server somewhere. It's not a file that can be deleted. It's energy in motion, traveling at light speed, for as long as the universe exists.
Some people use it to mark life's biggest moments. Others use it to capture something small — a feeling, a snapshot of who they were on a particular day. Both are equally valid. The universe doesn't care about the occasion. It carries all messages with the same fidelity.

How it compares to other time capsules
Buried time capsule — Physical objects sealed in a container and buried. Vulnerable to water damage, corrosion, construction, and being forgotten. Average survival rate: ~20%. Typical lifespan: 50–100 years before loss or degradation.
Digital time capsule — Files stored on servers or cloud services. Dependent on the company surviving, servers running, and file formats remaining readable. Average digital service lifespan: 5–15 years. Even major platforms shut down (Google+, GeoCities, Vine).
Cosmic time capsule — A radio signal transmitted into space. No physical container to degrade. No server to go offline. No company needed to maintain it. Once transmitted, the signal is independent of everything on Earth. It travels at light speed through the vacuum of space for millions of years. Nothing can stop it, nothing can alter it, nothing can delete it.
This isn't marketing hyperbole — it's physics. A radio wave in a vacuum is one of the most persistent phenomena in the universe.

Perfect for milestones
Many people send a cosmic time capsule for a specific occasion. Here are the most popular:
New baby — Parents send messages on behalf of newborns. The child's "first words to the universe." Years later, the family can check the Signal Tracker and see how far their child's message has traveled — a connection to the cosmos that grows with them.
Wedding / anniversary — Couples send love letters to the stars. The framed certificate makes a stunning wedding gift or anniversary present.
Graduation — A snapshot of who you are at a turning point. What you hope for, what you're afraid of, what you believe.
Memorial — Honoring someone you've lost. Their memory, traveling through the universe forever. The most permanent tribute you can give.
Just because — No occasion needed. Some people simply want to say "I was here, and I mattered." That's reason enough.

Track your capsule in real-time
Unlike a buried time capsule you might forget about, your cosmic time capsule comes with a live tracking page. From the moment of transmission, you can see exactly how far from Earth your message has traveled — updated every second.
Watch it pass the Moon (1.3 seconds after transmission). Then the Sun (8.3 minutes). Then Mars (varies by orbital position). Then Jupiter. Then Saturn. Within about 5 hours, your message has passed Pluto's orbit. Within a year, it's one light-year from Earth — 9.46 trillion kilometers.
The Signal Tracker works indefinitely. Check it on the anniversary of your transmission. Check it in five years, ten years, fifty years. Each time, the number will be larger. The message will be further. The connection will be deeper.

A certificate to keep
Every cosmic time capsule comes with a verified Transmission Certificate — a permanent record of your message. It includes the message text, destination star, transmission date, station coordinates, signal frequency, batch number, and a SHA-256 cryptographic verification hash that proves authenticity.
Digital Certificate (PDF) — Included with every purchase. Beautifully designed, downloadable, printable. The founding price is $19.
Printed Certificate ($49) — Premium printed document on archival-quality paper. Shipped to any address worldwide.
Framed Certificate ($99) — Museum-quality framing, ready to hang. The physical artifact to accompany your cosmic one. Makes an extraordinary gift or display piece.

The longest-lasting thing you'll ever create
Think about everything humans have built. The Great Pyramid of Giza is 4,500 years old — impressive, but it's eroding. The oldest known cave paintings are 45,000 years old — remarkable, but they'll eventually fade. The oldest rocks on Earth are 4.4 billion years old, but they'll be consumed when the Sun expands into a red giant in ~5 billion years.
A radio signal in space outlasts all of it. Long after the Sun has consumed the Earth, your message will still be traveling through the galaxy. Long after the Milky Way has merged with Andromeda (in ~4.5 billion years), the electromagnetic energy of your words will still be propagating through the expanded universe.
There is literally nothing else you can create in your lifetime that will last as long as a cosmic time capsule. Not a building, not a book, not a digital file. A radio signal in the vacuum of space is, for all practical purposes, eternal.
