The world is such an interesting place, filled with weird and interesting facts that you might have never realized were true. Everywhere we go, we find something different, unique and interesting, that we have never heard before. While some are easily understandable, there are others that turn us into deep thinkers. Today, we have gathered a list of facts that are sure to give you something to ponder.
1. Southwest Airlines flies people in need to hospitals, free of charge.
The company’s Medical Transportation Grant Program partners with nonprofit hospitals to provide complimentary, round-trip tickets for patients and their caregivers. According to Southwest Airlines, to date, more than $31.6 million in free transportation has been distributed in 40 cities in 25 states since the program’s inception in 2007. (source)
2. Entrapment law in the US does not mean that undercover officers have to tell you they are cops; even if you ask them flat out. Police have every right to lie to you about anything, at any time, undercover or not.
Contrary to common belief, police officers are under no obligation to reveal their law enforcement status with you. Even if you ask them flat out, they could look you right in the eyes and lie to you about anything, anytime; undercover or not. However, what they cannot do is to persuade you into doing things that you wouldn’t have considered under normal circumstances. (source)
3. In 2013, a scientific study found that fast-food restaurant ice may be dirtier than toilet water.
An investigation by The Mail found that ice served in six out of ten popular restaurants contained more bacteria than the water found in their toilets. The study followed popular fast-food chains such as McDonald’s, Burger King, KFC, Starbucks and Cafe Rouge and the results were conclusive. According to experts, this is mostly due to the fact that lavatory bowls are cleaned more often than the ice machines. Also, none of the samples found presented an immediate health danger. (source)
4. The wingspan of a Boeing 747 is longer than the Wright brother’s first flight.
Brothers, Orville and Wilbur Wright are credited with inventing and building the world’s first successful airplane and making the first controlled powered and sustained heavier-than-air human flight on December 17, 1903. During their first flight, Orville Wright was at the controls and managed to fly for 12 seconds, for a distance of 120 feet. The Boeing 747’s wing-span is 195 feet, which is longer than the Wright Brothers first flight. (source)
5. When we breathe through our nose, we always inhale more air from one nostril than with the other one.
Our nostrils go through a process called “nasal cycle” where they automatically take turns inhaling and exhaling the majority of the air. The process ensures that the workload is even between the two. When we have a cold or stuffy nose, the reason why it sometimes becomes so hard to breathe is because it could be the same day that the clogged one has its turn to work for the day. (source)
6. If you were to remove all of the empty space from the atoms that make up every human on earth, the entire world population could fit into an apple.
Everything we see in the Universe is made of atoms. For instance, a human hair, one of the narrowest things visible to the eye is around a million atoms across. To put things in another perspective, there are more atoms in a glass of water than glasses of water in all the oceans in the world. According to the BBC, if you were to remove all the empty space in the atoms that make up a human being, he or she would be a lot smaller than a grain of salt. If you removed all the empty space from the atoms that make up all the humans on the planet, then you could fit all 7.7 billion of us inside a single apple. (source)
7. If you somehow found a way to extract all of the gold from the core of our planet, you would be able to cover all of the land in a layer of gold up to your knees.
According to geologist Bernard Wood of Macquarie University in Australia, there’s enough gold in Earth’s core to coat its surface in 1.5 feet of the stuff. “We can say that more than 99% of the Earth’s gold is in the core,” Wood says. “It’s a nice image to think we could all step outside and be knee-deep in the stuff”.

8. The atmosphere around the sun is much hotter than the actual surface of the sun.
According to NASA, the sun’s surface is blisteringly hot at 10,340° F, but its atmosphere is another 300 times hotter. Normally, one would assume that when you move away from the sun, it would be cooler, but in this case, it gets hotter. Although scientists did not previously know exactly why this happens, today, they know that its because of nanoflare; because they have one-billionth the energy of a regular flare. According to a NASA scientist, millions of them are going off every second across the sun, and collectively they heat the corona. This is why the sun’s atmosphere is hotter than the actual sun.

9. Laughing while being tickled is actually a panic response from your body.
If you laugh while being tickled, then it’s a way of your body responding to panic and anxiety. It is thought that this is a defense mechanism when your body detects an external touch. By reacting instantaneously to an external touch, others around you become aware that there’s something that could be dangerous. According to scientists at the University of Tuebingen, tickling activates the part of our brain that anticipates pain. Furthermore, the laughter from being tickled is part of a defense mechanism and researchers believe that our responses to tickling date back to man’s earliest evolution and developing self-awareness.

10. All of the water on Earth would form a ball that’s 860 miles wide.
About 71% of the surface of the Earth is covered with water. If all of Earth’s water (oceans, icecaps and glaciers, lakes, rivers, groundwater, and water in the atmosphere) was put into a sphere, then the diameter of that water ball would be about 860 miles; which is a bit more than the distance between Salt Lake City, Utah to Topeka, Kansas.
