The animation is pretty good and helps to easily understand the phenomenon

For real, not what I expect to come across when checking out more in-the-weeds topics. Super accessible, even for a layman like me.

Not a big fan of the music though, sounded like I left another video playing in the background at points.

this looks like those bot comments on youtube videos.

Maybe you're a bad judge of what comments are botted?

It is. I wish the conspiracy theorist 'the pyramids could not have been built by humans' etc etc crowds didn't exist, because I wish there was space to theorise about pre-human, pre-ape intelligent culture just for fun. Same with UFOs. It seems to have changed in the past few years, but for a long time interest in them was associated with wackiness, and it was not something you could really discuss with a genuine sen…

That ol' Silurian Hypothesis is fun, but, knowing how damn smart birds are, it's not inconceivable that the theropods could have become advanced enough to be at least tool-users. Of course, now, we know they probably had as much similarity to lizards as we do. Another interesting thought experiment is an octopus civilization. They are probably smart enough to have also developed along those lines. Depending on what t…

In a couple million years, what you’ll see are the mineral deposits where dumpsters are today, with all the materials that are not economically viable to recycle, but that will remain as they were for very long times - metal alloys, rocks that shouldn’t have formed at that time and place, oil deposits where plastics were that appear much older than the adjacent substrate in carbon dating, and so on.

The shape is erased, but the chemical composition mostly remains.

> that it might only take a couple of million years, to completely wipe all traces of even an advanced, mechanized civilization. It depends who comes searching. u235 has a half-life of ~700m years, so finding it in enough places (i.e. rocket silos, even if underground) and obviously processed into spheres, would raise some advanced alien eyebrows. There's also a chance that some things we left on the Moon / in high o…

Items degrade but what often remains is imprint of it in surrounding material, that over time becomes rock. We dumped enough shit all around us that is too smooth/right angled/whatever to look like natural product. If anybody digs enough, they will find enough evidence, direct or indirect. That is, till all currently-up tectonic plates submerge for melting. But since they don't move by same speed, some of it will pro…

It all depends on how long. Eventually all the current surface will be sucked under tectonic plates and come out after passing some time in the mantle. We can plan for that by planting evidence in places that aren’t likely to go through that, but, give enough time, most of the crust will be recycled.

I didn't say it was a bot comment, I said it looks like a bot comment. Many of the shorts Youtube shows me are almost identical to that message.

One interesting techno-signature a civilization that happened hundreds of millions of years ago would be odd mineral deposits. It's never the Silurians, but it's fun to pretend we found something interesting.

Oil or rather Petroleum I mean, can an ant tell that a highway or skyscraper is artificial?

From their individual perspectives, it has been there since the beginning of time and will remain there long after they are gone.

That's actually a bit wild that Chile isn't refining or smelting copper. Is it because there's not the energy capacity to run smelters? I thought Chili had a pretty abundant energy grid (mostly hydro as I recall).

Australia behaves the same way, exports ore to China and buys back the refined products. Both countries have abundant energy (hydro and solar) but have old fashioned mining interests in charge.

Why do the mining interests prefer exporting it to selling to some local processor? you could probably get similar prices and the transport wouldn't be as complex, right?

It’s gotta be coins though. Most famous example was Louis XIV who created medals specifically to preserve French history for future archaeologists. At that time they realized that they knew almost everything about Romans and Greek through preserved medals. So the King created a vast medal series ( Histoire Métallique) intended to outlast paper, books, and buildings. These bronze and gold medals were intentionally bur…

They’ll last thousands of years, but not millions.

I was literally thinking ancient civilizations/aliens throughout the whole article.

It’d need to be really ancient in this case. To the point only mineral traces and no structure would remain.
