When reaching adulthood, you would probably understand and learn about the fundamental knowledge around the world. Learning new facts everyday that change the way you think abou the world rapidly. However, the world is full of mysteries that experts still can't explain and their facts remain as an unsolved mystery. Here are 50 of those facts that will make you question everything,
You already know not to put tin foil and metal forks in the microwave, but what about grapes? In 2011, a physicist at the University of Sydney went viral after he placed a grape in the microwave and filmed the fiery aftermath.
But oddly enough, scientists couldn’t explain the phenomenon until fairly recently. A March 2019 study published in Proceedings of the National Academy of Sciences reported that the fruity fireball occurs as a result of the loose electrons and ions that cluster to form plasma when grapes get hot.
Earth doesn’t feel so enormous once you learn that the sun alone makes up somewhere between 99.8 and 99.9 percent of all the mass in the entire solar system, according to the experts at University of California, San Diego. The rest is split between the planets and their satellites, as well as the comets, asteroids, dust, and gas. What’s more, it would take one million copies of our home planet to fill up the space inside of the sun, according to Cornell University.
Planes burn a lot of fuel transporting passengers around the world, which is why Qantas airlines, one of the largest carriers in Australia, has been looking for eco-friendly alternatives. One option? A blended fuel that is half conventional fuel and half cooking oil. The end result produces around 60 percent fewer carbon emissions than traditional options.
Qantas chief executive Alan Joyce told ABC, “We need to get ready for a future that is not based on traditional jet fuel or, frankly, we don’t have a future.”

Can you imagine how little you would get done if there was bubble wrap covering your walls? Engineer Al Fielding and Swiss inventor Marc Chavannes probably didn’t consider that when, in 1957, they invented bubble wrap while trying to create a textured wallpaper by sealing two shower curtains together to trap air bubbles. Fortunately, the partners soon realized that their invention was much better suited as a packing material.
5. Bed bugs have existed since the time of the dinosaurs.
Bed bugs are near impossible to get rid of and can spread faster than watercooler gossip. But that might also be why they’ve managed to stick around for so long. Scientists believe that the bugs have existed since the time of the dinosaurs, coming onto the scene about 115 million years ago, according to a 2019 study in Current Biology.
“To think that the pests that live in our beds today evolved more than 100 million years ago and were walking the earth side by side with dinosaurs was a revelation,” said researcher Mike Siva-Jothy. “It shows that the evolutionary history of bed bugs is far more complex than we previously thought.”
Diwali is the festival of lights, which is why the celebration includes plenty of fireworks. And while the dramatic displays thrill participants and onlookers, they also create a sudden increase in air pollution. According to the India Times, breathing the air in Mumbai during Diwali is “like smoking 113 cigarettes every day for 7 days.”

If you’re not sure how hot it is outside, listen to the crickets. The musical creatures adjust their signature sounds according to the temperature, which means that if you count how many times a cricket chirps in 15 seconds and then add 37, you’ll get a number that’s in the range of the temperature in Fahrenheit.
Despite the many differences between humans and other creatures, there are also plenty of similarities. Many other animals have hair, a heart, eyes, and a powerful brain just like ours. But one thing we don’t share is our chins.
“If you’re looking across all of the hominids, which is the family tree after the split with chimpanzees, there [are] not really that many traits that we can point to that we can say are exclusively human,” James Pampush, co-author of The Enduring Puzzle Of The Human Chin, told NPR. “The one thing that really sticks out is the chin.”
That puppy-dog look that your canine companion gives you is completely adorable, totally intentional, and something that they’ve developed since they’ve become man’s best friend. A 2019 study in the Proceedings of the National Academy of Sciences explained that domesticated dogs have evolved to have facial muscles around their eyes that wild wolves lack.
These muscles give our pets the ability to make certain expressions that are intended to communicate with humans, such as raising their eyebrows to make them look like they’re sad or pouting.
You might think that cheese, chocolates, or cookies are the ideal food pairings for a glass of champagne. But according to Marie-Christine Osselin, Moët & Chandon’s wine quality and communication manager, french fries might actually be the best thing to nosh with your bubbly. Osselin told The Drink’s Business that the saltiness and crunchiness of fries complement the acidity and bubbles in the champagne.
Between May 18 and July 26, the sun doesn’t set at all in Sommarøy, Norway. That’s why this village, which is located north of the Arctic Circle, wants to eliminate the concept of time so that they can get the most out of their 24 hours.
“There’s constant daylight, and we act accordingly,” said resident Kjell Ove Hveding in a statement. “In the middle of the night, which city folk might call ‘2 a.m.,’ you can spot children playing soccer, people painting their houses or mowing their lawns, and teens going for a swim.”
The residents went so far as to host a town hall about the proposed change in June 2019, although some critics ask how a lack of time would change what these folks already do.
You’ve likely been saying “cheese” for the camera since you were a kid. However, in the early 19th century, people attempted to capture the ideal expression by saying “prunes.” Apparenty, the cue helped keep subjects’ mouths “prim,” according to the Washington Post. Former Full House stars Mary-Kate and Ashely Olsen have reportedly used the same trick for years in order to present the perfectly relaxed pout to the paparazzi.
The number of thunderstorms you witness tends to depend on where on the planet you live. For instance, the U.S. experiences an estimated 100,000 thunderstorms each year. However, overall, there are 16 million thunderstorms annually on Earth. That breaks down to about 2,000 thunderstorms at all times, according to NASA.
Shellac is sometimes called “confectioner’s glaze,” due to the fact that it gives a shiny coating to candies like jelly beans and candy corn. But whatever you happen to call it, shellac, which is also used as a brush-on colorant and a wood finish, comes from the excrement secretions produced by female Kerria lacca insects. In other words, it’s bug poop.
It’s not always easy being a left-handed person in a right-handed world. In fact, it can be downright dangerous. According to The Mirror, more than 2,500 people who are left-handed die every year due to an injury caused by using equipment designed for people who are right-handed. Apparently, “the right-handed power saw is the most deadly item.”

Back on July 25, 2001, “blood-red rain fell over the Kerala district of western India,” according to The Guardian. The strange drops ended up “turning local people’s clothes pink.” Yellow, green, and black rain also fell in other districts in the area, according to India’s National Newspaper. It’s believed that the rainwater turned various colors due to the fact that the wind had swept up similarly colored sand before it came down with the rain.
He’s not just flying around without any authority! In 1927, Saint Nick got a pilot’s license from the assistant secretary of commerce for aeronautics, William P. MacCracken.
According to the Library of Congress, “The old saint called at the Commerce Department in Washington” and when he arrived, his picture was taken as he was given his license, airway maps, “and the assurance that the lights would be burning on the airways on Christmas Eve.”
We tend to think of woolly mammoths as ancient creatureswho roamed the Earth long before humans hit the scene. But the fact is, these giant animals were still around when the Great Pyramids of Giza were built, around 2580 to 2560 BC. The last woolly mammoths disappeared from Wrangel Island in the Russian territory of the Arctic Ocean just 4,000 years ago, according to the BBC.
When you sneeze, your eyes automatically close for a moment. But if you sneeze in a car that’s traveling at 60 mph, then your eyes will be closed for around 50 feet. According to one 2014 British study by Halfords Autocentres, Brits who are temporarily unable to see due to sneezes are the cause of 2,500 accidents each week.
