From the first ‘computer’ to ancient manuscripts, fields of jars and centuries-old landscape carvings, these are the real-world mysteries the experts are still scratching their heads over.
1. Antikythera mechanism
The 2,000-year-old Antikythera mechanism found in an ancient Greek shipwreck has been dubbed the “first computer,” using a wind-up dial system to track celestial time of the Sun, Moon, and five planets, along with a calendar, the phase of the Moon, and the timing of eclipses.
It was more sophisticated than any other tool that would be invented for the next 1,000 years, which sparked theories that it must have come from aliens.
While most researchers don’t stand behind that theory, they still aren’t sure how the Greeks managed to create a tool so much more advanced than anything we’ve seen of that era.

2. Voynich Manuscript
The Voynich Manuscript was written in Central Europe 600 years ago, but scholars still have no idea what the pages say or even what language it is, as it’s the only known example containing its looped alphabet.
Researchers put forward new translations every year, but none have stuck so far.
Recently, artificial intelligence suggested the words are Hebrew written in code (as previous experts have also proposed), but that study was only able to match 80 percent of the words to Hebrew, and even then produced incoherent sentences.
The Voynich Manuscript has been been carbon dated back to the 1400s and includes illustrations of plants that don’t resemble any known species. Read more about it and check out these equally freaky unsolved mysteries.
3. Plain of Jars
Amid mountains in Laos, a field is home to the Plain of Jars.
The massive stone jars – some are almost ten feet tall – are from 2,500 years ago, and no one knows why they’re there.
Nearby human bones suggest the jars might have been used for burial or to house decomposing bodies before being cremated or going to another part of the funeral process.
Meanwhile, locals say the vessels held whiskey for a mythical giant, or rice wine to celebrate giants helping them defeat enemies.
Undetonated U.S. bombs from the Vietnam War are still scattered in the area, so only seven of the 60 Plain of Jars sites are open to the public.
