The Court Jester Whose Wit Saved His Life

How a court jester slapped the king's butt, then brilliantly convinced him not to kill him Triboulet served as court jester under King Francis I, who ruled France from 1515 to 1547 . Triboulet's quick humor rescued him from Francis I's deadly wrath, not once, but twice. Court jesters hold a unique place in history.

Mystery of Enormous Gravity Hole in the Indian Ocean

Scientists Crack Mystery of Enormous Gravity Hole in the Indian Ocean



Giant ‘gravity hole’ in Indian Ocean possibly caused by ancient sea that sank millions of years ago.

A huge, mysterious so-called “gravity hole” under the Indian Ocean might have been formed from the remnants of an ancient sea, according to a new study.

Researchers recently offered the possible origins of a massive expansive depression at the bottom of the sea — where Earth’s gravity is at its weakest.

The new study makes the case that the Indian Ocean Geoid Low (IOGL) is made up of slabs from the long-lost Tethys Ocean that sank within the planet millions of years ago, according to Scientific American.

The IOGL spans about 2 million square miles (about two-thirds the size of the lower 48 US states) and is more than 600 miles below Earth’s crust, according to Science Alert. 

And according to the new study published in Geophysical Research Letters, it could have been caused when the Tethyan slabs “perturbed” the African Large Low Shear Velocity province, which is also known as the “African blob,” leading to plumes beneath the Indian Ocean.

“These plumes, along with the mantle structure in the vicinity of the geoid low, are responsible for the formation of this negative geoid anomaly,” lead author Debanjan Pal and Attreyee Ghosh wrote in the study.

The origin of the “gravity hole” might have finally been explained thanks to a new study.


The Tethys Ocean existed tens of millions of years ago, separating the mega-continents of Gondwana and Laurasia, according to Scientific American.

There have been different theories to explain the gravitational anomaly.

“All these [previous] studies looked at the present-day anomaly and were not concerned with how this geoid low came into existence,” the study states.

The results were based on more than a dozen computer models, Scientific American reported.

The depression is deep in the Indian Ocean.


Geophysicist Shijie Zhong told the outlet the study offers an interesting take that could help better understand the IOGL.

“We like to talk about the positive gravity anomalies, such as the superplumes over Africa and the Pacific,” he said. “But the geoid low in the Indian Ocean is one of the most profound gravitational anomalies on our planet.”

The gravity hole likely took its current shape about 20 million years ago and will likely last millions more, Pal reportedly said.

Arne Cheyenne Johnson

Arne Cheyenne Johnson: The Devil Made Me Do It Arne Cheyenne Johnson claimed that possession by the Devil had led him to murder Born on February 26, 1952, Arne Cheyenne Johnson holds a somewhat strange claim to fame. He was the first person in the United States to claim demonic possession as a defense in a criminal trial. After being arrested for the murder of his landlord, Alan Bono, in 1981 Johnson claimed, “the Devil made him do it”. Unsurprisingly, his trial became a media sensation at the time and Johnson became a household name. Amazingly, two famous paranormal investigators, Ed and Lorraine Warren, came to his defense, arguing at trial that Johnson truly was possessed. For decades this has left some wondering if Johnson was guilty or if the devil really made him do it. The Murder To an outsider, it would seem everything was going okay for Arne Johnson in early 1981. He was happily engaged to Debbie Glatzel, had just moved into a new home, and was working as a tree surgeon at...

Sending kids in the mail

When People Used the Postal Service to ‘Mail’ Their Children A U.S. POSTMAN CARRYING A BABY BOY ALONG WITH HIS LETTERS In the early days of U.S. parcel service, there weren’t clear guidelines about what you could and couldn’t mail. In January 1913, one Ohio couple took advantage of the U.S. Postal Service’s new parcel service to make a very special delivery: their infant son. The Beagues paid 15 cents for his stamps and an unknown amount to insure him for $50, then handed him over to the mailman, who dropped the boy off at his grandmother’s house about a mile away. Regulations about what you could and couldn’t send through the mail were vague when post offices began accepting parcels over four pounds on January 1, 1913. People immediately started testing its limits by mailing eggs, bricks, snakes and other unusual “packages.” So were people allowed to mail their children? Technically, there was no postal regulation against it. “The first few years of parcel post service—it was a bi...
