So if you’re looking to appear intelligent at your next get-together, do your best to memorize these mind-blowing bits of trivia. You’ll be flying high by flaunting your knowledge in no time.
With this in mind, here are some amazing scientific facts that I hope will inspire you to learn something new every day — they’ve certainly done so for me.
1. Water can boil and freeze at the same time
Seriously, it’s called the ‘triple point’, and it occurs when the temperature and pressure is just right for the three phases (gas, liquid, and solid) of a substance to coexist in thermodynamic equilibrium.
2. Lasers can get trapped in water
Oh my gosh, yes. Not only is this an incredible example of total internal reflection, it also shows how fiber optic cables work to guide the flow of light.
3. An egg looks like a crazy jellyfish underwater
A cracked egg on land might make a big mess, but 60 feet below the surface of the ocean, the pressure on the egg is 2.8 times atmospheric pressure, and it holds it all together like an invisible egg shell.
4. This is what happens when a black hole swallows a star
As the star gets sucked up into the black hole, a huge jet of plasma is burped out, spanning hundreds of light-years. “When the star is ripped apart by the gravitational forces of the black hole, some part of the star’s remains falls into the black hole, while the rest is ejected at high speeds.
5. You can see without your glasses
All you need to do is make a pinhole with your hand, which will help you focus the light coming into your retina. Sure, it won’t give you 20/20 vision, but it’s a good start if you’ve left your glasses at home.
6. Popping your knuckles isn’t necessarily bad for you
One researcher popped the knuckles of one hand for 60 years but not the other, and found no difference in the amount of gap between the two of them at the end of his experiment.
7. If you spin a ball as you drop it, it flies
I mean, it really flies. It occurs when the air on the front side of a spinning object is going the same direction as its spin, which means it gets dragged along with the object and deflected back.
8. Babies have around 100 more bones than adults
Babies have about 300 bones at birth, with cartilage between many of them.With age, many of the bones fuse, leaving 206 bones that make up an average adult skeleton.
9. The Eiffel Tower can be 15 cm taller during the summer
When a substance heats, its particles move more and it takes up a larger volume –known as thermal expansion. For this reason, large structures such as bridges are built with expansion joints which allow them some space to expand and contract without causing any damage.
10. Amazon Rainforest produces 20% of Earth’s oxygen
Thankfully, plants continually replenish our planet’s oxygen levels through photosynthesis. During this process, carbon dioxide and water converts into energy, releasing oxygen as a by-product. Covering 5.5 million square kilometers (2.1 million square miles), the Amazon Rainforest cycles a significant proportion of the Earth’s oxygen, absorbing large quantities of carbon dioxide at the same time.
11. Hawaii moves 7.5 cm closer to Alaska every year
The Earth’s crust is split into gigantic pieces called tectonic plates. These plates are in constant motion, propelled by currents in the Earth’s upper mantle. Hawaii is in the middle of the Pacific Plate, which is slowly drifting north-west towards the North American Plate, back to Alaska. The plates’ speed is comparable to the speed at which our fingernails grow.
12. It takes 8 minutes, 19 seconds for light to travel from the Sun to the Earth
In space, light travels at 300,000 kilometres per second. Even at this breakneck speed, covering the 150 million odd kilometres between us and the Sun, it takes considerable time.
13. Stomach acid is strong enough to dissolve stainless steel
Your stomach digests food thanks to highly corrosive hydrochloric acid with a pH of 2 to 3. This acid also attacks your stomach lining, which protects itself by secreting an alkali bicarbonate solution. The replacement of the lining is necessary continually, and it entirely renews itself every four days.
14. The Earth is a gigantic magnet
Earth’s inner core is a sphere of solid iron and the outer layer is of liquid iron. Variations in temperature and density create currents in this iron, which in turn produce electrical currents. Lined up by the Earth’s spin, these currents combine to create a magnetic field, used by compass needles worldwide.
15. Venus is the only planet to spin clockwise
Because of the common origin, all the planets move around the Sun in the same direction and on roughly the same plane. They also all spin in the same direction (anti-clockwise if observed from ‘above’) – except Venus. Venus defiantly spins in the complete opposite direction. The most likely cause of these planetary oddballs are gigantic asteroids which knocked them off course in the distant past.
16. The Earth appears to have a whole new underground continent called Zealandia
The discovery itself isn’t new – some geologists have been arguing for its existence for many years. However, in 2017 a team of scientists concluded Zealandia fulfills all the requirements to be considered a drowned continent.
17. Your appendix might not be a useless organ after all
Research suggests it might play a role in the immune system as a secondary defensive organ, acting as a “safe house” for helpful gut bacteria.
18. The world’s smallest fidget spinner is 100 microns wide
It is smaller than the width of a human hair and is barely visible to the naked eye.
19. Bird’s Flying Ability
It seems the best fliers lay more “pointy” or elliptical shaped eggs while the others lay rounded or oval-shaped eggs.
20. The blue whale can produce sounds up to 188 decibels
It is the loudest sound produced by a living animal and has been detected as far away as 530 miles.
21. The Missing letter ‘J’
The only letter that doesn’t appear on the periodic table is J. Don’t believe us? Check it out for yourself.
22. The Temperature of Lightning
A lightning strike can reach a temperature of 30,000 C or 54,000 F. Lightning hits about 400 people each year. Shocking!
23. What a Butterfly!
The Queen Alexandra’s Birdwing is the world’s largest butterfly, with a wingspan of up to 12 inches. It is an endangered specie and found only in Papua New Guinea.
24. Einstein’s Stolen Brain
After Albert Einstein’s death in 1955, pathologist Thomas Harvey removed Albert Einstein’s brain from his body. Rather than putting the brain back in the body, Harvey decided to keep it for study. Harvey did not have permission to keep Einstein’s brain, but days later, he convinced Einstein’s son that it would help science.
25. Mercury Without Moon
While the planet Mercury may resemble our own moon in many ways, it has no moon of its own.
26. Unique Tongue
Giraffe tongues are dark blue or purplish and it’s around 20 inches in length. The length of their tongues allows them to browse for very highest, juiciest leaves on their favorite acacia trees, and the melanin in their tongues may protect them from UV rays—that is, getting sunburned.
27. An Extra Heart
Love octopus? They’ll love you more, with their three hearts. Two hearts are used to pump blood to each of the octopus’ lungs, and the third pumps blood throughout the body.
28. Tortoises more than a Century
Galapagos tortoises can live to be well over 100 years old. They also are the largest of all living tortoises, measuring up to 4 feet (1.2 m) long and weighting of over 350 lbs (158.8 kg).
29. Heavyweight Ants
Ants are capable of carrying objects 50 times their own body weight. Relative to their size, ant muscles are thicker than those of larger animals or even humans. This ratio enables them to produce more force and carry larger objects.
30. The Mysterious 95 Percent
Humans can only see about 5 percent of the matter in the universe. The rest is made up of invisible matter (called dark matter) and a mysterious form of energy known as dark energy.
31. Heavyweight Cloud
The average weight of a cloud is equal to that of 80 elephants.The volume of a cloud is higher than the weight of itself. This makes the gases fly. But it is certainly not that light and fluffy as it seems.
32. The human mind thinks in logarithmic calculation
Logarithmic calculation deals with multiplication and division whereas algebraic deals with addition and subtraction. In simple terms, Buy 1 get 2 offer seems more attractive to the human mind than Buy 50 get 51 offer, even though in both the case we receive only one product as free.
33. So mysterious…
It is scientifically proven that a woman will find a man sexier if he wears a pair of sunglasses. This is because sunglasses make your face appear more symmetrical and can make you appear mysterious. Both of which can increase your perceived attractiveness.
34. The Light Moon
If you lived on the moon, you would weigh a lot less than you do now. Gravity on the moon is one-sixth of the gravity on Earth. This is because the moon has only 1% of the mass of Earth. A human’s weight will vary depending on what planet they are on.
35. More Powerful Than Sun
A lightning bolt is astonishingly 5 times hotter than the sun’s surface.
To put it in the most delicious way possible: a single lightning bolt has enough energy to cook 100,000 pieces of toast.
36. Too Cool
A fire can be started with ice. The trick? Carve the ice into a lens that focuses the sun’s rays, much like a magnifying glass.
37. Please Don’t Go
The moon is slowly drifting away from our planet, by about 1.48 inches, or 3.78 centimeters every year.
38. Getting Over It
The average human being will walk a distance equivalent to three times around the world, just within their lifetime.
39. More Power
Female sharks have thicker skins than their male counterparts. Scientists think it’s because males like to bite females during mating.
40. How to find that a person likes you?
Although there are no accurate signs that someone is attracted to you, there are many subtle behaviors or activities that have been linked to someone showing attraction which includes:
- Raising their eyebrows when they first look at you.
- Parting their lips while you make eye contact.
- Grooming one’s hair, either fixing it or messing it up.
- Letting you “check out” their body.
- Soft touches to your elbows, forearms, and occasionally the small of the back.
41. Rats laugh when being tickled
These creatures are more dynamic then we think. Rats have the ability to “laugh” when tickled. A National Geographic video demonstrated that rats respond positively to tickling. And they even chase after the researcher’s hand in a playful manner..
42. Diamond Rain on other planets
Diamonds are definitely the Milky Way galaxy’s best friends.The atmospheres in all four planets(Neptune, Uranus, Jupiter, and Saturn) have such extreme pressure that they can crystallize carbon atoms and turn them into diamonds.Separately, according to a research, a conclusion came that it may rain as much as 2.2 million pounds of diamonds on parts of Saturn every year.
43. It’s impossible to burp in space
When you burp on Earth, gravity keeps down the solids and liquid from the food you just ate, so only the gas escapes from your mouth. In the absence of gravity, the gas cannot separate from the liquids and solids, so burping essentially turns into puking.
Now let’s talk about some one-line facts:
44. The largest man-made lake in the U.S. is Lake Mead, created by the Hoover Dam.
45. The Stegosaurus dinosaur measured up to 30 feet long but had a brain the size of a walnut.
46. The human eye blinks an average of 4.2 million times a year.
47. The ears of a cricket are located on the front legs, just below the knee.
48. Sound travels about four times faster in water than in the air.
49. House flies have a lifespan of two weeks.
50. Starfishes don’t have brains.
51. The average person falls asleep in seven minutes.
52. Shrimp’s hearts are in their heads.
53. Porcupines float in water.
54. An ostrich’s eye is bigger than its brain.
55. Hummingbirds are the only animals able to fly backward.
56. Tigers have striped skin, not just striped fur.
57. A crocodile’s tongue is attached to the roof of its mouth.
58. Six months in space can make your body seem 20 years older.
59. Each teaspoon of soil contains more bacteria than there are people on the planet.
60. Your blood makes up about eight percent of your body weight.
These strange but true facts proves that the world really is a marvelous and mysterious place!!
