Time Capsules: Preserving the Present

A **Time Capsule** is a form of communication across time. By sealing objects, information, or artifacts in a secure container, we attempt to tell the humans (or beings) of the future who we were and what we valued.

The Crypt of Civilization

One of the most ambitious time capsules on Earth is the **Crypt of Civilization** at Oglethorpe University in Georgia. Sealed in 1940, it is a 2,000-cubic-foot room containing everything from a microfilm of the Bible to a set of Abraham Lincoln's dentures. It is scheduled to be opened in the year **8113 AD**—a date chosen because it is as far into the future as the first Egyptian calendar is in the past.

The Voyager Golden Record

A time capsule doesn't have to stay on Earth. Launched in 1977, the **Voyager Golden Record** is a phonograph record attached to both Voyager spacecraft. It contains 115 images, sounds of nature, greetings in 55 languages, and a selection of music from around the world. Because it is traveling through the vacuum of space, it could last for millions of years, potentially outlasting the human race itself.

The Digital Time Capsule Problem

Storing physical objects is relatively easy; storing digital data is much harder. Software becomes obsolete, hardware decays, and file formats disappear. Modern "digital time capsules" use specialized materials like synthetic DNA or glass-etched archives to ensure that our family photos and Wikipedia entries don't become unreadable "digital dark age" artifacts within a single century.

Conclusion

A time capsule is an act of hope—the belief that there will be someone there to open it. On the Epoch Clock, we count every second because each one is a building block for the history someone else will eventually find.
