The discovery that the universe is expanding at an accelerating rate contradicts past popular opinion that the universe will decelerate, with the all-powerful force of gravity winning yet again. However, with the discovery of a possible anti-gravity force, new fields of study will open up in order to explain this quandary. This discovery could also challenge current thinking on the history of space and time. The discovery of our accelerating universe is such a new discovery that the future prospects are still in the air. However, as the acceleration of the universe continues, within billions of years, many of the stars we can see today will be gone from view. Robert Kirshner, of the Harvard-Smithsonian Center for Astrophysics, stated that "The universe will become a very different place to look at."

Expansion of the universe

...answer your questions, but you should at least register it with them as extra insurance of not losing track of where you put it.

I wouldn't expect most photo printer paper to last 25 years.

So don't use photo printer paper. Get archival-quality photographic prints made at a professional photography shop. Some of those are rated to last for decades in a viewable format (where UV can damage them). I'm sure they'll be fine in a sealed container.
I'd also make a point of looking over what the International Time Capsule Society has to say. I'm sure they've answered questions you haven't even thought to ask.

...that it's at least 8000 years away and thus, no matter what, we will have a chance to open the crypt of civilization up!!!

Ah, it should hold up at least as long at the Crypt of Civilization time capsule at Oglethorpe University. That time capsule is scheduled to be opened in the year 8113.

IIRC it was a small blurb in Scientific American a few years back (perhaps even pre-Y2K) where I first read of the LongNow Clock, and it got me interested in other long-term projects and ideas as well (which there aren't many).

There's a HUGE time capsule at Oglethorpe University called "The Crypt of Civilization". Most time capsules you may have read about are small things about the size of a shoebox meant to be opened 50 to 100 years after they are sealed. The "Crypt" was a (indoor, apparently) swimming pool (emptied of water, of course) loaded up with many artifacts and sealed in 1930, and scheduled to be opened in about 6,000 years.

Oglethorpe is also the home of The International Time Capsule Society. Notable pages on the website are Tips on Building a Time Capsule and The Nine Most Wanted Time Capsules.

As I discussed on the forum at that site, it would be interesting to couple one or more time capsules to such a clock, to have each capsule be opened at a pre-programmed time.

Disclaimer: I have no connection to Oglethorpe, just a fan of the site, and the "most prolific" contributor to the site's time capsule forum (three of the six posts).

The clock is certainly a "Next-Generation" design, bring the very first Y10K-compliant device.
