Science Facts That Fill Us With Awe And Creep Us Out
From the depths of the world's oceans to the stars in faraway galaxies, the world is an awe-inspiring place. Some amazing science facts might give you the chills in a good way - but others will give you the creeps.
And sometimes facts about the universe give you both at the same time. Vote up the ones that elicit these conflicting feelings.

The Closest People To Earth's Point Nemo Are In The International Space Station
Point Nemo, officially known as “the oceanic pole of inaccessibility,” is the point in the ocean that is farthest away from any land.
The Pacific Ocean spot, named after the captain from Jules Verne's Twenty Thousand Leagues Under the Sea, is surrounded by more than 1,000 miles of ocean in every direction, and the closest landmasses to it are the Pitcairn Islands to the north, the Easter Islands to the northeast, and an island off the coast of Antarctica to the south.
With the land closest to Point Nemo more than 1,000 miles away in every direction, the astronauts aboard the International Space Station are the closest humans to the point, as the station is only 258 miles from Earth.

Humans Could Survive In Space With No Spacesuit For A Few Minutes, But Would Lose Consciousness Within 15 Seconds
When astronauts put on their spacesuits, a pressurized, oxygenated atmosphere is created. The suits also protect them from extreme temperatures and ultraviolet rays, and allow them to breathe correctly. If humans tried to go into space without a spacesuit on, they might last around 15 seconds.
Without a spacesuit to protect it, the human body would begin to lose consciousness and eventually suffer from ebullism due to lack of oxygen, which would cause the formation of bubbles in the moisture of the eyes, mouth, and skin tissue.
In 1965, a NASA astronaut Jim LeBlanc survived when he was exposed similar conditions in a training exercise gone wrong. "As I stumbled backwards, I could feel the saliva on my tongue starting to bubble just before I went unconscious and that’s the last thing I remember."

Rain Once Fell On Earth For About 1 Million To 2 Million Years Nonstop
Around 232 million years ago, rain fell almost everywhere during a span known as the Carnian age. After millions of years of dry climates, Earth entered this wet period, and stayed in it for nearly 2 million years.
Scientists think the Carnian episode contributed to the evolution of dinosaurs like the Stegosauraus and Tyrannosauraus because of massive geological changes that took place.

If The Sun Were Replaced By A Black Hole, We Would Not Fall In - We Would Freeze To Death First
According to NASA, a black hole is a place in space where gravity pulls so much that even light can't get out. The gravity is so strong because matter has been squeezed into a tiny space.
If the sun were to turn into a black hole, humanity would not fall in; instead, we would all freeze to death. The black hole that was the sun would not emit any light or heat, so we would be in a pitch-black world with freezing cold temperatures.

Scientists Captured Video Evidence Of Sharks Living In A Volcano
After dropping a camera into the main crater of the Kavachi volcano located in the Solomon Islands, scientists found footage of sharks living in the underwater crater. The team left the camera underwater for an hour, and when they brought it back up to watch what was recorded, the footage showed images of silk sharks, hammerhead sharks, jellyfish, snappers, and a stingray.
The scientists aren't sure what happens to the sharks when the volcano is actively erupting, but believe that they are able to sense imminent eruptions and temporarily leave the crater.

The Surface Of Mercury Can Reach Lows Of -290 F Despite Being So Close To The Sun
Even though Mercury is the smallest planet in our solar system and is closest to the sun, its surface temperatures can become extremely cold. Because the planet doesn't have an atmosphere to retain heat, temperatures can drop below -290 F.
Though temperatures on the planet can become unbelievably cold, at other times temperatures can reach highs of 800 F.
