Tombstones That Last? 54
Reality Master 101 asks: "Being an engineer, I've always been annoyed by the quality of the average tombstone. The typical marble kind only seem to last a maximum few hundred years before the lettering gets worn away. Old-school stone ones were better, but you still max out at about 500 years. This started me asking the question of what would I make one out of that would last 1000 years? 10,000 years? Clearly a solid gold or silver tombstone would last without corroding, but that would be uneconomical and would probably be stolen. What material would give the most bang for the buck for lasting power? What other factors come into play when you start talking Egyption timespans? I was also thinking that I should mount the tombstone to the casket so it doesn't fall over or otherwise wander away." It's odd the links to things that you can find over the internet, so when I read this question, I was reminded of one of Piro's recent rants on MegaTokyo that starts off with an odd discussion about this very issue. Might the information passed in the beginning of the rant be a reason why tombstones made today don't last very long? Do Tombstones need to last for over 500 years, anyways?

Oh really? And what makes you think that perpetual care will accually exist byond your time? Sure it will continue for a few years or so, but for how long? Stable goverments for more then 1000 years are rare. I'm not certian that any have made it that long. Future historians interested in the life of people from the 20th century (which will be interesting if they figgure out what we have done, even if it seems primitive by their standards), but they won't have much to go on. CDs hav been claimed to last 100 years, not 1000. Stone in a desert has been proven to last, but climates have been known to change. Indeed if you can find a way to make deserts grow odds are they will become argracultural areas. (Look at Chile, theyhave the dryest desert, no rain in over 500 years, but they irrigate it - who knows what this will do to your tombstone.
Personally I want to be burried in an unmarked grave in the middle of a field. I want my body to become fertialiser. When my soul (whatever you belive, you get the concept) no longer inhabbits my body I don't care what happens to it, if my body can be useful to others, then that is fine with me.

There are tons of grave yards that have been dug up and the tombstones placed on a wall somewhere because the land was needed for something else. And the pressure on land is only growing. I wouldn't give current grave yards a snowball's chance in hell of surviving out the next century without being paved over.
Do yourself and future generations a favour. Get cremated, have your ashes scattered somewhere that meant something to you, and build your legacy by having good children rather than a long-lived gravestone.

The pigment is embedded in the plastic, not just a thin layer that's painted on. Take a durable material (granite or maybe ceramic -- ceramic would certainly be easier). Make the letters of the inscription be veins of tinted material that go all the way through.
That way, no matter how worn down the monument gets, the writing will still be readable, especially if the surface is ground down a bit.
two simple options (Score:2)
First, I'd seriously consider granite. It is available from all regular sources and it doesn't noticably degrade over the 100 year timespan (I did a bit of 'field research' a few years back: comparing the apparant degradataion of tombstones of different materials in local graveyards) If you are really worried about long term readability, you could spend a bit extra for a larger monument with deeper inscriptions.
Another option, that you probably won't find at the regular sources, is glass. Tempered glass several inches thick is unlikely to be easily shattered and should resist acid rain fairly well. The inscription could be embeded beneath a clear outer layer to add some extra resistance to environmental damage. I haven't any idea where you would go to get a glass tombstone, or how much you would expect to pay.

Perpetual Maintenance (Score:1)
Actually, your best bet for a perpetual monument is to have a separate well-funded foundation which is in charge of maintaining the monument. Of course, to be fail-safe you should have several cooperating foundations which are geographically disperse and operating under the protection of unrelated governments, so as to avoid destruction by war, economic, political, religious, or legal changes.
Certainly, the foundation would have paid the cementery for its maximum maintenance fund. But your foundation would be responsible for monitoring that maintenance is suitable and deal with special situations. If the cementery closes, a highway is routed through your final resting place, or molten rock dissolves your monument, then the foundation would have funding and specifications for building a replacement at a suitable site.
Or just write a great book, one which you'd be proud to have as your memorial, and hope that libraries and Project Gutenberg will preserve it for you.
Aluminum (Score:2)
Only corrodes in a monoatomic layer, so it never really "rusts" more than an atom or two thick. Dull finish, so it's not as enchanting as stainless steel (many of which still corrode). Might be recycled by someone, but I wouldn't exactly call that an insult. Now, if your stone tombstone were ground up and used for road construction.... Magnesium is in the same category, but, well, a bit tempting to ignite for those who can identify it.
The real problem with tombstones is that they are not acid-resistant. Not a problem a centuries ago, but with the advent of fossil fuels and acid rain, probably quartz would be a good choice. You can make your own by passing large amounts of current through things, and they're experimenting with this now as a way of permanently and intertly dealing with nasty chemicals. Maybe just cast yourself something in glass.
The problem here is that rain is mildly acidic (something like 5.6) even when clean and not polluted.
The solution? You need to become such a person among humanity that society will pick up the bill of maintaining your tombstone forever.

You don't even have to do that; there is a thing out there called Perpetual Care. You (or more likely, your survivors) pay a chunk of change up front. The care for the plot (and sometimes the stone itself) come out of the interest payments.
This is probably safer than having society pick up the bill; if you're one of those people, you're likely to be stripped bare by a 24th century descendant of Lara Croft, well after you'd be able to enjoy it.

Plastics in general are bad choices. A glass-filled PTFE might have the requisite toughness and chemical/UV resistance, but they still char in fire (a cemetary is bound to have grass or forest fires if left unmaintained for long enough). Many plastics just fall apart by themselves after a few tens of years, as the Smithsonian has found out. Stick with hard stone (granite, basalt, obsidian?) or ceramics.

Maybe if the markers designated the site of an honorable death, I might understand. 99.9% of the time, they don't. I gave a couple of examples. Here's another: There's a cluster of four crosses I pass on my daily commute. They mark the location where four people died pushing an out-of-gas vehicle, with no lights on, across a high-speed divided highway at 3AM. There is no cross at this location for the driver who hit their unlit vehicle on the dark highway at 3AM. I'm sure he has a nice headstone in the proper place, though.
I can't be certain, but I doubt there are Darwin Awards on the crosses. There probably could be.

An everlasting tombstone (Score:1)
Well, lets see if we set some rather lofty goals:
+Lasts 10,000+ years
+Over that period it retains its structural integrity.
+Any inscriptions/designs/etc should still be intact (And perhaps a "rosettas stone" of sorts, for future civilizations)
+And since this marking your grave, a method for retaining your remains/mementos/etc in an air-tight containter so they last as long as the tombstone.
The only feasible solution I can think of is to avoid the ever changing Earth and simply be blasted into space.
This method allows for you to be placed in any form of container (within reason- it has to fit in the rocket) and of most types of materials (as long as you are incased in something to protect you from the hazards of space- your actual tomb could be inside this casing). You could even be aimed in a direction that avoids as much objects as possible- You might even be able to go for millenia undisturbed!
Think about it: Some alien race may find your capsule and decide to place you in their museum! Or they could just decide to eat you, but at least you lasted that long!
As far as I know, this is actually something that was planned to be available to the public, instead you would blast your cremated remains into space in a small rocket. I vaguely remember hearing about Gene Roddenbury's widow planning to blast some of his cremated remains into outer space. I don't know whether the company that was offering it ever actually succeeded in doing this, but it was planned.
So, I suppose that if you had enough money you could possibly have your physical form and your tombstone (of sorts) to last for billions of years in the vastness of space.

Alas, we need to find a material that won't corrode (or otherwise get destroyed in all but the most severe of weather conditions). Perhaps the solution lies in redundancy. First, make a granite (not marble) tombstone and carve with all the details. That should last you a while.
After doing this, encase the entire thing in titanium. Carve again. The titanium shell should last you a few centuries, I believe, and even if it falls away you'll still have a few more centuries worth of granite to erode before it disappears.
