71 most interesting and unexpected facts

#Fact 1: About one million metric tons is the mass of a cloud

To stay afloat, clouds generally have a volume of about 1 km3 and a density of around 1.003 kg per m3. This is about 0.4 percent lower than the surrounding air density.

#Fact 2: Lightning is 30 times more likely to strike a giraffe than a human

True, there are just five well-documented fatal lightning strikes on giraffes between 1996 and 2010. But due to the population of the species being barely 140,000 during this period, it makes for roughly 0.003 lightning kills per thousand giraffes each year. This is 30 times the same mortality rate for people.

#Fact 3: Identical twins don’t have the same fingerprints

You can’t blame your sins on your twin, after all. This is because environmental conditions during development in the womb (umbilical cord length, position in the pregnancy, and the pace of finger growth) affect your fingerprint.

#Fact 4: Earth’s rotation is altering speed. It’s actually slowing

This indicates that, on average, the duration of a day grows by roughly 1.8 seconds each century. 600 million years ago a day lasted barely 21 hours.

#Fact 5: Your brain is continually consuming itself

This process is termed phagocytosis  when cells engulf and eat smaller cells or molecules to eliminate them from the system. Don’t worry! Phagocytosis isn’t detrimental but really helps retain your gray matter.

#Fact 6: The longest chunk of fossilised dinosaur excrement discovered is nearly 30cm long and over two liters in volume

Believed to be a Tyrannosaurus rex poo, the fossilised feces (also dubbed a ‘coprolite’) is helping scientists better comprehend what the dinosaur ate.

#Fact 7: The Universe’s average hue is dubbed ‘Cosmic latte’

In a 2002 research, scientists found that the light emanating from galaxies averaged into a beige tone that’s near to white.

#Fact 8: Animals can experience time differently from humans

To smaller animals, the world around them moves more slowly compared to humans. Salamanders and lizards, for example, experience time more slowly than cats and dogs. This is because the experience of time depends on how rapidly the brain can absorb incoming information.

#Fact 9: A chicken once lived for 18 months without a head

Mike the Chicken’s astonishing achievement was documented back in the 1940s in the USA. He lived as his jugular vein and most of his brainstem was left relatively intact, ensuring just enough brain function remained for survival. In the majority of situations, a headless chicken dies in a couple of minutes.

#Fact 10: All the world’s germs placed on top of each other would span for 10 billion light-years

Together, Earth’s 0.001mm-long microorganisms could wrap around the Milky Way almost 20,000 times.

#Fact 11: Wearing a tie can lower blood flow to the brain by 7.5 percent

Research in 2018 discovered that wearing a necktie can restrict the blood flow to your brain by up to 7.5 percent, which can make you feel dizzy, and nauseated, and induce headaches. They can also increase the pressure in your eyes if worn too tight and are wonderful at transporting viruses.

#Fact 12: The fear of long words is termed Hippopotomonstrosesquippedaliophobia

The 36-letter term was originally employed by the Roman poet Horace in the first century BCE to condemn those writers with an inordinate love for big phrases. It was American poet Aimee Nezheukumatathil, probably terrified of their surname, who invented the phrase way we know it in 2000.

#Fact 13: The world’s oldest dog lived to 29.5 years old

While the normal age a dog achieves seems to be approximately 10-15 years, one Australian cattle dog, ‘Bluey’, survived to the ripe old age of 29.5.

#Fact 14: The world’s oldest cat survived to 38 years and three days old

Creme Puff was the oldest cat to ever live.

#Fact 15: The Sun creates a sound but we can’t hear it

In the form of pressure waves, the Sun does create a sound. The wavelength of the pressure waves from the Sun is measured in hundreds of miles, however, meaning they are well beyond the range of human hearing.

#Fact 16: Mount Everest isn’t the highest peak on Earth

Mauna Kea and Mauna Loa in Hawaii, the twin volcanoes, are taller than Mount Everest due to 4.2km of their heights being buried underwater. The two volcanoes stretch an astounding 10.2km in total, compared to Everest’s meager 4.6km.

#Fact 17: Our solar system has a wall

The heliopause — the region of space in which solar wind isn’t hot enough to drive back the wind of particles originating from distant stars – is sometimes regarded as the “boundary wall” of the Solar System and interstellar space.

#Fact 18: Most maps of the world are inaccurate. 

On most maps, the Mercator projection — initially devised in 1569 – is still used. This approach is extremely wrong and makes Alaska look as huge as Brazil and Greenland 14 times larger than it is. For a map to be accurate, it would need to be life-size and circular, not flat.

#Fact 19: NASA truly faked part of the Moon landing

While Neil Armstrong’s first feet on the lunar surface were certainly not fabricated, the astronaut quarantine process after the astronauts got back on Earth was just one huge show.

#Fact 20: Comets smell like rotten eggs

A comet smells like rotten eggs, urine, burning matches, and… almonds. Traces of hydrogen sulphide, ammonia, sulphur dioxide, and hydrogen cyanide were all identified in the constitution of the comet 67P/Churyumove-Gerasimenko. Promotional postcards were even commissioned in 2016 bearing the unpleasant aroma of a comet.

#Fact 21: Earth’s poles are migrating. 

This magnetic reversal of the North and South Pole has happened 171 times in the previous 71 million years. We’re overdue a flip. It might arrive soon, as the North Pole is advancing at roughly 55 km per year, an increase above the 15km per year up to 1990.

#Fact 22: You can truly die laughing 

And a few individuals have, generally owing to extreme laughing triggering a heart attack or asphyxia. Comedy programs should come with caution.

#Fact 23: Chainsaws were initially invented for birthing

It was invented in Scotland in the late 18th Century to help facilitate and speed up the process of symphysiotomy (widening the pubic cartilage) and removal of disease-laden bone during birthing. It wasn’t until the start of the 20th Century that we started employing chainsaws for woodchopping.

#Fact 24: Ants don’t have lungs

 They instead breathe through spiracles, nine or ten small apertures, depending on the species.

#Fact 25: The T.rex likely possessed feathers. 

Scientists in China uncovered Early Cretaceous era tyrannosaur bones that were coated in feathers. If the ancestors of the T. rex possessed feathers, the T. rex probably did, too.

#Fact 26: Football teams wearing red uniforms play better.

The hue of your attire may alter how you’re regarded by others and change how you feel. An examination of football matches in the previous 55 years, for example, indicated that teams wearing a red uniform consistently fared better in home matches than teams in any other colour.

#Fact 27: Wind turbines kill between 10,000 and 100,000 birds each year in the UK

Interestingly, painting one of the blades of a wind turbine black can minimize bird mortality by 70 percent.

#Fact 28: Snails have teeth

between 1,000 and 12,000 teeth, to be precise. They aren’t like ours, though, so don’t be thinking of snails with ludicrous toothy smiles. You’ll discover the snail’s tiny ‘tooth’ scattered over its file-like tongue.

#Fact 29: Sound can be negative decibels

The quietest spot on Earth is Microsoft’s anechoic room in Redmond, WA, USA, at -20.6 decibels. These anechoic chambers are made out of thick concrete and brick and are positioned on springs to block vibrations from entering through the floor.

#Fact 30: A horse generally possesses more than one horsepower

Research in 1993 indicated that the highest power a horse can produce is 18,000W, roughly 24 horsepower.

#Fact 31: Your signature might disclose personality traits

Research in 2016 asserts that among men, a larger signature correlates with higher social boldness while, among women, a bigger signature connects with narcissistic tendencies.

#Fact 32: One in 18 persons has a third nipple

Known as polythelia, the third nipple is produced by a mutation in dormant genes.

#Fact 33: Bananas are radioactive

Due to being rich in potassium, every banana is somewhat radioactive thanks to carrying the natural isotope potassium-40. Interestingly, your body has roughly 16mg of potassium-40, suggesting you’re around 280 times more radioactive than a banana already. Any extra potassium-40 you obtain from a banana is flushed out within a few hours.

#Fact 34: There’s no such thing as a straight line

Zoom in close enough to anything and you’ll find abnormalities. Even a laser light beam is somewhat bent.

#Fact 35: Deaf persons are known to utilize sign language in their sleep

A case study of a 71-year-old man with rapid eye movement disorder and a significant hearing impairment revealed he employed proficient sign language in his sleep, with researchers able to gain an idea of what he was dreaming about owing to those signs.

#Fact 36: Hippos can’t swim

Hippos do have large bones, so huge and solid that they’re scarcely buoyant at all. They don’t swim and instead execute a slow-motion gallop on the riverbed or the sea floor. Hippos can even sleep underwater, according to a built-in reflex that allows them to bob up, take a breath, and then sink back down without awakening.

#Fact 37: The Moon seems upside down in the Southern Hemisphere

Compared to the Northern Hemisphere, anyhow. This implies that the ‘Man in the Moon’ is upside down in the Southern Hemisphere and appears more like a rabbit.

#Fact 38: You might be very pregnant and not realize it

Cryptic pregnancies aren’t that rare, with 1 in 500 not detected until at least halfway through and 1 in 2,500 not known until labor starts.

#Fact 39: Somebody has been constipated for 45 days

In 2013, an unhappy Indian woman had to undergo surgical excision of a faecal lump as huge as a football.

#Fact 40: You travel 2.5 million kilometers a day around the Sun without noticing

The Earth’s orbit travels roughly 2.5 million kilometers concerning the Sun’s core and around 19 million km with respect to the center of the Milky Way.

#Fact 41: There are more bacterial cells in your body than human cells

The average person is roughly 56 percent bacteria. This was identified in a 2016 research and is significantly less than the former estimates of 90 percent. As bacteria are so light, however, by weight, each individual is over 99.7 percent human.

#Fact 42: Most ginger cats are male

There are usually three ginger male cats to one ginger female. This is because the ginger gene is present on the X chromosome, so female cats would require two copies of the gene to turn ginger but males only need one.

#Fact 43: Your nails grow faster in warmer summers

This is presumably due to increased blood flow to the fingers. It might be because you’re less worried when on holiday hence less prone to bite away at ‘em.

#Fact 44: Insects can fly up to 3.25km above sea level, at least

Alpine bumblebees have been observed surviving as far up as 3.25km above sea level and could even fly in experimental circumstances that simulate the air density and oxygen levels at 9km – that’s slightly higher than Mount Everest.

#Fact 45: There’s a planet primarily constructed from diamond

Called 55 Cancrie, it’s approximately twice the size of Earth and some 40 light-years away from us within the Cancer constellation.

#Fact 46: Animals can be allergic to humans

Animals might be allergic to human dead skin cells — dander. These allergic reactions might be precisely like ours, too, including breathing difficulty and skin discomfort.

#Fact 47: Being bored is a ‘high arousal state’ medically

This is because when you’re bored your heart rate increases.

#Fact 48: Platypuses sweat milk

This is because it doesn’t have teats. Milk appears like perspiration on a platypus, although it’s an aquatic creature thus it doesn’t sweat at all.

#Fact 49: LEGO bricks sustain compression better than concrete

A regular plastic LEGO block can hold the weight of 375,000 additional bricks before it collapses. This, potentially, would allow you to build a skyscraper exceeding 3.5km in height. Scaling this up to house-size bricks, however, would cost much too much.

#Fact 50: Martial artists who grin before the start of a battle are more likely to lose

This might be as a grin can express fear or submissiveness.

#Fact 51: It’s practically hard to acquire too much sugar from fresh fruit

While the sugar in fruit is largely fructose and glucose (fructose is what’s turned into fat in your body), you can’t acquire too much sugar from fresh fruit. Fresh fruit includes a lot of fiber and water which slows down your digestion and helps you feel full.


#Fact 52: You don’t like the sound of your voice

because of the bones in your head. This may be because the bones in our skull make our voice seem deeper.

#Fact 53: A rainbow on Venus is termed a glory.

Appearing as a series of colored concentric rings, they are formed by the interference of light waves within droplets, rather than the reflection, refraction, and dispersion of light that creates a rainbow.

#Fact 54: Protons look like peanuts, rugby balls, bagels, and spheres

Protons come in various forms and sizes, with their appearance altering according to the speed of smaller particles within them: Quarks.

#Fact 55: Mirrors facing each other don’t generate limitless reflections

Each reflection will be darker than the last and gradually fade into obscurity. Mirrors absorb a part of the energy of the light striking them. The total amount of reflections mirrors can produce? A couple hundred.

#Fact 56: There could be a cure for ‘evil’

Well, a cure for psychopathy, anyhow. Psychologists suggest that components of psychopathy may be ‘cured’ by cognitive behavioral treatment, which is said to minimize violent offenses by persons with the disorder. A preliminary study reveals that computer-based cognitive training might enable a psychopath to experience empathy and regret, too.

#Fact 57: All mammals get goosebumps

When your hair stands on end, small muscles tighten at each hair’s root which distorts the skin to cause goosebumps. This mechanism is termed piloerection and is found in all animals. Hair or fur is utilized to trap an insulating air layer.

#Fact 58: Football players spit so much because exertion raises the quantity of protein in saliva

When you exercise, the amount of protein produced in the saliva rises. A protein mucus dubbed MUC5B makes your saliva thicker while you’re exercising which makes it more difficult to swallow therefore we tend to spit more. It may occur during activity because we breathe through our lips more. MUC5B might activate to protect our lips from drying up, consequently.

#Fact 59: Some animals have autistic-like symptoms

Autistic features in animals include a predisposition toward repetitive conduct and abnormal social routines.

#Fact 60: The largest butterfly in the world has a 31cm wingspan

It belongs to the Queen Alexandra’s Birdwing butterfly, which you may find in the woods of the Oro Province, in the east of Papua New Guinea.

#Fact 61: You remember more nightmares when you sleep badly

Research says that if you sleep badly and wake up numerous times during the night you will be more likely to recall the content of any dreams you experienced. You are also more likely to remember a dream when woken from one.

#Fact 62: You might sweat when you’re anxious to inform others

One idea indicates we’ve evolved to sweat when worried to notify the brains of other people around us so they are prepped for whatever it is that’s making us anxious. Brain scans have indicated that when you inhale the perspiration of a panic-induced individual, areas of the brain that manage emotional and social cues light up. When you’re stressed your sympathetic nervous system releases substances like adrenaline, which activates your sweat glands.

#Fact 63: The longest someone has held their breath underwater is nearly 24.5 minutes

The world record for breath-holding underwater was reached by Croatian Budimir Šobat on 27 March 2021, who held his breath for a total of 24 minutes and 37 seconds. On average, a human can hold their breath between 30-90 seconds.

#Fact 64: Dogs bend their heads when you talk to them to better identify known words

 Your dog is bending its head when you talk to it to determine where noises are coming from more rapidly. This is done to listen out more correctly for common terms such as ‘walkies’ and allows them to better grasp the tone of your voice. If a dog doesn’t turn its head that much (as those with shorter muzzles do), it’s because it depends less on sound and more on sight.

#Fact 65: If the Earth twice in size, trees would immediately tumble over

This is because surface gravity would be doubled. It would also imply that dog-size and larger animals would not be able to sprint without breaking a leg.

#Fact 66: Mercury, not Venus, is the nearest planet to Earth on average

On average, Mercury is 1.04 astronomical units (AU) distant from Earth compared to the 1.14 AU average distance between Earth and Venus. One AU is equal to the average distance between the Earth and the Sun. Venus still comes closest to Earth as part of its orbit around the Sun, however.

#Fact 67: Flamingoes aren’t born pink

They come into the world with grey/white feathers and only gain a pinkish tint after starting a diet of brine shrimp and blue-green algae.

#Fact 68: People who eat everything they want and stay slender have a sluggish metabolism, not fast. 

A slender individual tends to have less muscle mass than others, meaning their basal metabolic rate (BMR) is lower than those of a large muscle mass – this gives them a slow metabolism, not a quick one.

# Fact69: Earth is 4.54 billion years old

Using radiometric dating, scientists have found that the Earth is 4.54 billion years old (give or take 50 million years). This makes our planet half the age of the Milky Way Galaxy (11-13 billion years old) and about a third of the age of the Universe (10-15 billion years old).

# Fact70: Beavers don’t actually live in dams

Technically, beavers reside in a lodge that they build behind a dam, amid a deep pool of water.

# Fact71: The average dinosaur lifetime was unexpectedly modest

The Tyrannosaurus rex, for example, attained full size between 16-22 years old and lived up to 27-33. The biggest dinosaurs such as the Brontosaurus and Diplodocus tended to live up to between 39-53 years old, maybe reaching the heights of 70.
