Am I insane?

For wanting to leave a legacy that will last, and a message for anyone or anything that finds it? No, that's not insane, that's understandable, I think.
What will determine the insanity quotient is the message you want to inscribe.
- In a few thousand years...
  "We finally deciphered the text on it. It's a monument to love, to undying loyalty and affection! How amazing! Here, it reads: 'Never gonna give you up, never gonna let you down'"
  
  Parts of it remain indecipherable without the social context, however, as the writer explicitly assumes a mutual knowledge of some set of unspecified rules.
  
  Can we all splurge on a cubesat with a vinyl record or some other media that contains "never gonna give you up" , and make our own voyager sattelite for other lifeforms to receive?
- The entire screenplay of Skrek 4.
  
  Skrek
  
  Only okay if you number it #4 and don't make the first three.
- Thousands of years in the future, our descendents will return to Earth, to visit museums of ancient culture, and marvel at the Tungsten Cube of Dickbutt.
- "Skibidi Toilet" is all the cube says.
  
  Oh boy is that going to be a perplexing mystery for future archeologists. I can already imagine a PhD student banging their head on a desk screaming: “none of this makes any sense”.
- Ea nasir's shitty copper complaint

Yes, you’re crazy. Stainless steel won’t last a million years. Not even close. You should go with titanium instead. That would also create a massive density difference between the two pieces in case someone lifts them up separately. Feeling the weight difference of the two pieces is very confusing for most people.
- This might blow your mind, but I currently have a titanium chastity cage.
  
  Your schlong will not last as long as that material allows for. So I'd go with a titanium casting of it, complete with vulgarities, like the graffiti in Pompeii

I think that is awesome
- Fuck you. Don't encourage me.
  
  You’re a genius and I love you.
  
  Have an email complaining about you etched onto it
  
  Do you want some discouragement?
  Stainless steel is stains less not rusts never. You would need additional measures to keep the stand from degrading over thousands of years. Your local archeology department could give you some pointers on how to accomplish that.
  Or maybe you design the stand in such a way that the tungsten object is held firmly, but still easily visible in rusty stainless jaws.

According to a US Army study, Iron and Tungsten could create galvanic action, causing both materials to degrade if in contact.

So at first glance, it seems like this combo wouldn't last as long as it could with just Tungsten.
- Informative. Thank you!

Ceramics…. There is an Isaac Asimov story where the only evidence they can find that humans used to live on Earth is the presence of what appear to be toilets and sinks. All else is dust.

I don't think this is crazy at all. It sounds like art. And we have lots of art that is meant to endure for centuries, like oil paintings.

Put the same text in 6 different languages (maybe: English, Mandarin Chinese, Hindi, Russian, Arabic, and Bengali to get as many scripts as possible?) on each side of the cube. Be the Rosetta Stone of the future. Be sure to get a native speaker to look over each text before you comission it.
That should be enough work to discourage you. :)

Eh, if you have the money, it's probably fine.
My current weird things:
Switched from my normal time zone to UTC on all my clocks.
Chose to study Esperanto instead of a more practical language because of its past of hopefulness
Plan on switching to a 13-month calendar in the future (is going to require modifying the opensource calendar I use to allow the change)
Switched to barefoot shoes not for health but the diminished cost in materials.
changed my keyboard to a dactyl manuform for the hell of it.
changed my keyboard scheme to Dvorak now.
changed my videogame control scheme from wasd to dcxf to accommodate the keyboard (in Dvorak that's exku).
We're all alittle eccentric. Some of us more than others.
- Mi ne pensas ke numero du estas stranga.

well if you get a tungsten cube your mortality will be cured so you will be around in a million years
- That is.... Epic.

You could also try to get a tungsten replica of your genital. It's probably more expensive though.
- All depends on the amount of material required.
- I'm not sure I've ever seen "genital" in the singular before, and now I'm trying to determine what qualifies as a singular genital and not the whole set of genitals.
  
  Good catch. Some may prefer one genitalius to indeterminately many genitalia.
- Tungsten is a bit expensive. Titanium however...

IMO, the real question is how to preserve it in deep time. Where is accessible enough but also protected? The best place would probably be a location that is heavily contaminated by toxic or nuclear waste. Those will likely remain time capsules in the near term, but remain as focal points in deep time. Find a spot that is likely to survive continental drift, the next super continent, and countless ice ages. I dare you. Do it! Make the ultimate geo cache.
- Dang didn't think of a nuclear site. Was thinking more along the lines of a protected area. The only problem with toxic environment would be protecting the material itself in a budget friendly way
- How about the bottom of Mariana tench? The intense pressure will make sure some Mr Rando can’t just pop in one day and smack it with a hammer. If you keep this relic in the remains of the exploded reactor in Chernobyl, some nut job can just run in, cause some damage and run away. Sure, they will pay with their life, but that won’t fix the hammer marks on the cube.
  Chemical dangers are another option, but those kinds of places aren’t stable for a million years. Some volcanoes spew sulfur dioxide, which would be a good repellant, but those vents open and close in unexpected ways.
- You are too smart to survive. You are the weakest link.

The cuneiform bit definitely seems like you're trying to troll across the ages. Why else would you do that?

I mean, if you have the money and inclination, sounds like a nerdy but pretty cool project!

Maybe, but in a good way. Do it!

We all are, together.
- That's optimistic.
  
  And here I thought I was a black pill everyone crushed up and snorted.

Nah I think about doing this shit all the time, I get overly technical with details trying to make it last as long as possible, tungsten is a great idea.

Size?
- Well that's a bit personal but I was thinking 10cm.

It sounds like an interesting project, actually. So, no, I don't think you are.

For bonus points shoot it into deep space. Maybe some alien civilization will run into it trillions of years from now.

Can I sign it?

Use copper, or it could have been brass (I don’t remember) this thing resists everything and lasts longer - and it’s even cheaper
- Hmmmm... https://flyingprecision.com/brass-vs-tungsten-steel-an-in-depth-comparative-analysis-of-mechanical-properties-and-uses/

Screw it go for it think the only thing holding you down is cost of materials and machining especially if you're adding a message to it, if its just an artifact/statue you're shooting for maybe opt for a more budget and workable material than tungsten. Some kind of industrial metal you can work with like steel or even aluminum may be a better alternative stone material (granite or marble) being the best IMO for longevity, encase it in epoxy and then put in a PVC pipe with desiccant for added measure. Finding a location where it won't be disturbed is probably the hardest part of this. Can't be exposed to UV light or harsh chemicals, so ocean is out (think its illegal to dump there too). If burying, it needs to be below the frost line for sure in fairly stable ground, with good chemical makeup of the soil, where people won't interact with it. I personally can't come up with a legal means so you might have to get permission from some kind of protected grounds like a national park or something. Even then at most it will last maybe a couple thousand years, longer if using stone material instead of metal
- You are not helpful.
  
  Can't wait for them to find your masterpiece in a couple of millennia

You wouldn't be the first! If you do do it, then you should make a video for us here on Lemmy ❤️

Why not just use actual cuneiform?
- You got me there. Too many extra words.

Whatever rocks your boat. Until you're not hurting anyone, commission away.

Inscribe as many different languages as you can. No telling which one theyll still know and it could be the next Rosetta Stone.
