Given that all direct evidence would be long gone after many millions of years, what kinds of evidence might then still exist?
It goes into detail about chemical traces and climate change, but if this civilization existed, they never got that far because they never used tools or machines at all. No tool-cut boreholes before ours have ever been found. Not so much as a single basement or water well or aquaduct in the geological strata. Forget oil or coal or mining for metal, much less thousands or millions of square miles of city and roadbeds ringing the planet. Itās just about the first thing we started doing. Digging. No digging means a much smaller realm for this civilization than I can find credible.
As I understand it the argument is that the record is so sparse that we canāt be sure to catch a ten thousand year blip on the radar if it was sufficiently long ago.
What Iām talking about, however, are the kind of events with a good chance, as these things go, of leaving traces in rocks for hundreds of millions of years. Spread those events out across ten thousand years and the whole planetā¦ we havenāt found any?
We donāt even have the same mountains, the same seas or the same continents.
The question is how confident we can be that the fact that we have found quite a few fossils of Mesozoic animals but never a āfossilā of a Mesozoic building or machine means that there never was such a thing. Just how big are the gaps in the record?
I think we have to agree to disagree. I feel that Mesozoic-made (or even Triassic-made, as an example, or older) structures, especially underground and stone structures, would leave excellent fossil traces compared to fossils of animals and plants.
The awful part is that a passenger died. The audio of the pilot making the emergency landing is amazing, though. I wanna be able to handle stress like that pilot for just one day, just so I know what it feels like.
So many articles like this. And itās always the same theme: the genius white teenage boy who gets so obsessed with the world of hacking that he loses his moral compass.
I have got to the point where I no longer think they are geniuses. Talented, but not geniuses.
And I also have to wonder where the hell the parents were in all this. I know what my parents would have done Iād had crappy grades and spent all my time (in their eyes) āplaying video gamesā. But hey, Iām a girl.
And if his grades were so crappy, how did he get into U of T? Their entrance average is usually pretty high compared to other universities in southern Ontario.
So I hadnāt seen this view of Pangea before, and in mulling it over I wondered why did all the above-sea-level land all start out in one place and then break up rather than just floating around randomly from the beginning. Turns out, Pangea wasnāt the beginning, and the formation and breaking up of supercontinents is cyclicalāPangea was just the most recent one(!)
So this is old news to any geologists among us but to a layman thatās pretty, uh, earthshaking.
There are all sorts of fascinating links from that one article. Hereās an animation of Pangaea splitting to form the modern continents (in the article Supercontinents):
Iāve always wondered what was on the opposite side of the middle of Pangaea. Just ocean?
