In this article, I will discuss science facts. Science has surprising to us every day with facts that sound unbelievable yet are 100% true. From the mysteries of space to the wonders of our own bodies, here are 10 mind-blowing science facts for you.
Fact #1. Bananas Are Radioactive
Explanation:
Did you know that Bananas contain potassium, which has a small amount of the naturally occurring radioactive isotope potassium-40. However, the levels are so low that they are completely harmless to humans.

Fact #2. Your Stomach Replaces Its Lining Every 3-4 Days
Explanation:
Did you know that the stomach lining is replaced every 3-4 days to protect it from the highly corrosive stomach acid that helps digest food? Without this constant regeneration, the stomach would digest itself.

Fact #3. The Earth Is Smoother Than a Billiard Ball
Explanation:
Did you know that if the earth were scaled down to the size of a billiard ball, it would actually be smoother? The relative height of mountains and the depth of ocean trenches are minor compared to Earth’s size.

Fact #4. Octopuses Have Three Hearts
Explanation:
Did you know that Octopuses have three hearts—two pump blood to the gills, while the third pumps it to the rest of the body. Interestingly, the heart pumping blood to the body stops when the octopus swims.

Fact #5. You’re Taller in the Morning
Explanation:
Did you know that he Overnight, your spine decompresses due to the lack of gravitational pressure. This causes you to be slightly taller in the morning compared to the evening.

Fact #6. Venus Is the Hottest Planet in the Solar System
Explanation:
Did you know that despite being farther from the Sun than Mercury, Venus is hotter due to its thick atmosphere full of carbon dioxide, which traps heat and creates a runaway greenhouse effect?

Fact #7. Humans Share 60% of Their DNA With Bananas
Explanation:
Did you know that Around 60% of human DNA is similar to banana DNA. This doesn’t mean we are part banana, but it reflects the shared genetic code for basic life functions like cell division and metabolism.

Fact #8. A Day on Venus Is Longer Than Its Year
Explanation:
Did you know that Venus is an intriguing planet because it takes 243 Earth days to complete one full rotation (a day), which is actually longer than its 225 Earth-day year. This means that a day on Venus is longer than a year on Venus! Its slow rotation is due to its thick atmosphere and strong gravitational interactions with the Sun. What’s even more interesting is that Venus rotates in the opposite direction compared to most planets, so if you were on Venus, the Sun would rise in the west and set in the east. Despite its slow rotation, Venus is still one of the hottest planets in our solar system, with surface temperatures hot enough to melt lead, thanks to its extreme greenhouse effect.

Fact #9. Lightning Is Five Times Hotter Than the Sun
Explanation:
Did you know that A lightning bolt is incredibly powerful, reaching temperatures of 30,000 Kelvin, which is five times hotter than the surface of the Sun, where the temperature is around 5,500°C. This intense heat is generated by the massive energy discharge of a lightning strike, causing air to ionize and create that bright flash we see during thunderstorms. Despite this extreme heat, the duration of the lightning strike is incredibly short, lasting only a fraction of a second, which makes it even more fascinating that such extreme temperatures can be reached in such a brief moment.

Fact #10. Your Bones Are Stronger Than Steel
Explanation:
Did you know that, pound for pound, human bones are five times stronger than steel? Their structure allows them to withstand significant pressure while being lightweight.
