Hum seems historically accurate

Yeah I think this is key

In ancient times knowledge was actually a secret thing. There was a big gap in knowledge & understanding between parts of the society. Nowadays it's not like that doesn't exist at all but knowledge has become a far more common thing. 

I love this stuff! Usually the most interesting thing about conspiracy theories is the mental shit people come up with based on such little evidence.

As for the antikythera mechanism, it depends what you mean by advanced. It doesn't display any mathematical knowledge that we didn't already know was common at the time and complex clockwork mechanisms like it were around 1400 years later so I suppose in that sense it was advanced for the time. So to answer the question in the thread title: maybe by their own standards but Is it evidence of aliens, time travel or anything like that? No, not a bit of it. I think the most interesting question is what was it for? No-one really knows. Maybe a teaching aid, maybe a military or religious thing to predict eclipses and that, which would explain why it wasn't more common. Fascinating though.

Anyway, great thread, well done!

Yeah this is true. Not just in ancient times though, there are examples of this all throughout history. I cam across a good one in a Bill Bryson book the other day: a doctor created the forceps for use in childbirth, something which is still used (albeit rarely) today, in the 16th century. He and his family kept it secret for around 100 years until it was developed by someone else, even going so far as to blindfold the woman giving birth. By not sharing this knowledge they effectively damned god knows how many women and children to a painful death during childbirth. I know this is off topic but I just thought it was interesting. 

For a more modern example see that Mojang patent-troll lawsuit. Kidding!

The lost continent of Lemuria, also known as Mu in the Pacific ocean.

they say they were visited by aliens over 13,000 BCE, before the Bering Strait bridge. They found skeletal remains on an island of the coast of California dating back 13,000 BCE.

i could be wrong i could be right. ancient lemuria sounds cool though.

@dath

Actually no we wouldnt. Scientists openly say our civilization would dissapear within 10,000 years. Perhaps a remote few objects would survive but the planet would have almost completly broken down everything weve made.

If an advanced civilization were around 150,000 years ago we would have nothing left from them even if they were our current size and tech.

I dont even belive its true but scientifically its certainly possible

No. But they invented some awesome stuff like Greek Fire and Damascus Steel ( they are many more) that we in this age have no idea how to replicate.

So looking at it from that point of view they were actually better than us in this age at some technologies.

In their time, then yes it was advanced technology. But if you're trying to compare that to now, then no. Back then, a compass was considered to be advanced technology. Before the late 1600's, everyone thought we were the center of the solar system. Then Galileo improved the telescope and proved that the sun was.

Yeah, the computer in question was connected with Arcemde's lab, and it was a gift to one of the Ceasers. (Spelling) It was thought that casting such small parts needed didn't happen until after DaVinci (One of his students was credited with coming up with the way small metal parts were cast, I watched a special on guns once, DiVinci started research on how to make a "self firing" mechinism.(I forgot the term used) But it wasn't possible to make piece that small with the state technology was at the time. But during the time of the "dark ages" a lot of progress was lost, because of various factors. (Fear, supersition, and the Catholic church, store houses of knowledge being ransacked by invaders to name a few)

Plus people just assume that ancient civilizations were populated by simpltons. Food for thought the major branches of mathematics Calculus, Geometry, Trignometry, were "founded" by these ancient civilizations, and are virually unchanged from the state they where in before the Dark Ages. But I'm babling so I will stop.

I will add some more. The thing is as pointed out in my post above. The dark ages did much disservice to the advancment of human civilization. But that is what happens when you go from a strong government (Rome) that protected the arts and go to a feudal system where infighting between the lords where they tended to destroy everything when they conquered. Rome was ransacked by these "barbarians" several times and since books that stored the information where not easily reproduced when they burned Rome just think of home much knowledge was lost.

The "barbarians" as they where labled by Rome were the feudal city-states that ended up replacing Rome.

As for the telescope it was a mixture of Caliprunicus (Spelling) and Galileo both had to deal with the Catholic church who also was part of the problem that was the middle ages.
