Bizarre Mysteries That Remain Unsolved to This Day

The bluestones—which weigh about four tons each—were sourced 200 miles away from Stonehenge. How were these heavy stones transported so far, and with such little technology available? There are no definite answers when it comes to this mysterious rock formation.

Naga Fireballs

Naga fireballs, also known as "ghost lights," are a phenomenon said to be seen annually on the Mekong River. Balls of glowing light supposedly rise from the water, floating several hundred feet in the air before disappearing entirely. The phenomenon is said to be caused by a giant serpent that lives in the Mekong known as phaya nak.

Written accounts from those who claim to have witnessed the Naga fireballs date back hundreds of years. Every October, the Nong Khai Province hosts the Phayanak Festival. On the final day of the celebration, attendees gather near the riverbank to watch the mysterious balls of fire rise from the waters and shoot up into the sky.

Beale Ciphers

The Beale Ciphers are a series of three ciphertexts that allegedly reveal the location of a buried treasure worth roughly $43 million as of 2017. The treasure was thought to belong to the mysterious Thomas Jefferson Beale, who buried thousands of pounds of gold, silver, and jewels in 1818 while prospecting in Colorado.
