From home-swallowing sinkholes to picturesque natural caverns, Danger Dolan counts down the 15 strangest holes on the planet.
Our planet certainly is immersed in danger, as attested by the dire statistic that 93 percent of the people who ever lived are now dead. By what and where are the most dangerous places on Earth? Take the Mariana Trench, the deepest part in any of our oceans located east of Mariana Island in the Western Pacific. If you were at the bottom of this trench, you’d be under seven miles of water, the pressure alone would crush your lungs, you’d be rendered unconscious in 15 seconds and dead in 90 seconds. In this edition of Vsauce, Michael Stevens previews our world’s many other dangerous locations that are definitely hazardous to your health.
Henry Reich tells us that the poorest places on the planet can also be the richest. Although this is especially prevalent in nature, it can also apply to the human landscape. “In nature, as in human society, plenty of resources doesn’t necessarily translate into ‘everyone gets plenty,'” Reich says. He gets into the nuts and bolts about why poor places are more diverse in this edition of Minute Earth.
“In the history of life on Earth, we know of five different mass extinctions when a majority of life on Earth at the time disappeared in the blink of a geologic eye,” says biologist and science writer Joe Hanson. The most cited is the Cretaceous-Paleogene Extinction 66 million years ago that wiped out the dinosaurs. But the most deadly was the mother of all extinctions called the End Permian, 250 million years ago, which obliterated 96 percent of Earth’s species. Hanson says we are now in the midst of the sixth mass extinction and we are the perpetrators. Hanson explains why in this edition of It’s OK To Be Smart.
It seems we’ve read or researched just about everything there is to know about our little blue planet. But Danger Dolan is betting there are at least 15 facts that will tickle your innards, such as the twin planet named Theia that crashed into Earth 4.5 billion years ago. The planet, about the size of Mars, was eventually absorbed into Earth’s crust. Check 14 more fascinating facts about our home.

Isaac Newton pegged it correctly when describing the colors in a rainbow. But terminology and technology changed drastically over the years, nearly eliminating the colors indigo and violet and re-introducing purple. Henry Reich explains in this fascinating edition of Minute Physics.
The Earth works in mysterious ways, including the baffling Taos Hum, a low-frequency noise in Taos, New Mexico, that can also be heard in other parts of the world. Although many such sounds are attributed to machines and industrial-related things, no one has been able to uncover the source of the Taos Hum. Join Danger Dolan as he features 14 more of the craziest natural phenomena on Earth.
