34 Pieces of Basic Knowledge That Most People Don’t Know

In the vast ocean of knowledge that spans across every conceivable subject, there are countless facts and pieces of information that, while basic, often elude the general populace. These tidbits can range from practical skills to simple facts about the world around us.

Here are 34 pieces of basic knowledge that, surprisingly, most people don’t know. Prepare to have your mind expanded with these intriguing insights!

1. The Sun is a Star

It might seem obvious to some, but many people don’t realize that the Sun, the central and largest object in our solar system, is actually a star. It’s a massive, glowing sphere of hot gases, primarily hydrogen and helium, undergoing nuclear fusion.

2. Water Expands When Frozen

Unlike most substances, water expands as it freezes. This anomaly is why ice floats on water, and it plays a crucial role in Earth’s climate and ecosystems.

3. The Moon Affects Earth’s Tides

The gravitational pull of the moon is primarily responsible for the high and low tides in Earth’s oceans. This gravitational force causes the water to bulge out on the side closest to the moon and on the side farthest from the moon.

4. The Earth is Not Perfectly Round

Our planet is an oblate spheroid, meaning it is slightly flattened at the poles and bulges at the equator. This shape results from the Earth’s rotation.

5. Antibiotics Can’t Treat Viral Infections

Antibiotics are effective against bacteria, not viruses. Taking antibiotics to treat viral infections, like the common cold or flu, is not only ineffective but can also lead to antibiotic resistance.

6. Humans Share 50% of Their DNA with Bananas

It’s a fun fact that underscores how all life on Earth is connected. This doesn’t mean we’re half banana, but it highlights the shared genetics across different species.

7. A Year Isn’t Exactly 365 Days

It takes the Earth about 365.25 days to orbit the Sun, which is why we have a leap year every four years to add an extra day and keep our calendar in alignment with Earth’s orbit.

8. Venus is the Hottest Planet in the Solar System

Though Mercury is closest to the Sun, Venus is hotter due to its thick, toxic atmosphere that traps heat, making it the hottest planet.

9. You Can’t See the Great Wall of China from Space

Contrary to popular belief, you cannot see the Great Wall of China with the naked eye from space. This myth has been debunked by astronauts.

10. The Difference Between Weather and Climate

Weather refers to short-term atmospheric conditions, while climate describes the average weather patterns over a longer period.

11. Sharks Have Been Around Longer Than Trees

Sharks have existed for about 400 million years, while the earliest trees appeared around 350 million years ago, making sharks one of the oldest living species on Earth.

12. Octopuses Have Three Hearts

Two hearts pump blood to the gills, while the third pumps it to the rest of the body. When an octopus swims, the heart that delivers blood to the body stops beating, which is why these creatures prefer to crawl rather than swim.

13. The Eiffel Tower Can Be Taller During the Summer

Metal expands in heat, so the Eiffel Tower can grow up to 15 centimeters (about 6 inches) during the summer months.

14. ‘I.e.’ and ‘E.g.’ Mean Different Things

“I.e.” stands for “id est” (that is) and is used to clarify a statement. “E.g.” stands for “exempli gratia” (for example) and is used to provide examples.

15. Different Parts of Your Tongue Don’t Taste Different Flavors

The idea that your tongue has specific zones for each taste (sweet, sour, salty, bitter) is a myth. All taste buds can detect all tastes, and they’re distributed all over the tongue.

16. Lightning is Hotter Than the Sun

The temperature of a lightning bolt can reach around 30,000 kelvins (53,540 degrees Fahrenheit), compared to the Sun’s surface temperature of about 5,500 kelvins (9,932 degrees Fahrenheit).

17. There are More Trees on Earth Than Stars in the Milky Way

Recent estimates suggest there are about three trillion trees on Earth, compared to 100-400 billion stars in the Milky Way.

18. Honey Never Spoils

When sealed in an airtight container, honey can last indefinitely due to its low moisture content and high acidity.

19. A Group of Flamingos is Called a Flamboyance

This fun fact highlights the beauty and grace of these pink birds when they gather in groups.

20. A Banana is a Berry, But a Strawberry Isn’t

In botanical terms, a banana qualifies as a berry, but a strawberry does not because its seeds are on the outside.

21. The Heart Doesn’t Feel Pain

While heart attacks cause chest pain, the heart itself doesn’t have pain receptors. The pain is referred from other areas.

22. More People Speak Mandarin Chinese Than Any Other Language

Mandarin Chinese is the most spoken language in the world, with over a billion speakers.

23. The Internet Weighs About as Much as a Strawberry

The digital information moving through the internet has a tiny, almost negligible mass, estimated to be around 50 grams.

24. Vikings Never Wore Horned Helmets

This common misconception has been perpetuated by media and folklore, but archaeological evidence shows no such helmets were used.

25. Coffee Can Help You Burn Fat

Caffeine can boost your metabolic rate and increase fat burning, making coffee a helpful addition to a weight loss diet.

26. Alaska is the Easternmost and Westernmost State in the U.S.

Due to the Aleutian Islands extending into the Eastern Hemisphere, Alaska can claim both titles.

27. You’re Taller in the Morning Than in the Evening

The cartilage in your spine compresses throughout the day, making you slightly shorter by the end.

28. The Shortest War in History Lasted 38 Minutes

The Anglo-Zanzibar War of 1896 is the shortest recorded war in history.

29. You Can’t Hum While Holding Your Nose

32. There Are No Natural Lakes in Ohio

Every lake in Ohio is man-made, a surprising fact given the state’s numerous water bodies.

33. The Canary Islands Are Named After Dogs, Not Birds

The name comes from the Latin “Canariae Insulae,” meaning “Islands of the Dogs.”

34. Wombat Poop is Cube-Shaped

This unique trait helps the poop not roll away, marking the territory more effectively.


Each of these facts opens up a window to a broader understanding of the world and challenges common misconceptions. Knowledge, no matter how basic, has the power to enlighten and inspire curiosity. Who knows what other fascinating discoveries await just around the corner of our everyday perceptions?
