Top 15 Amazing Facts about Science

Science, too, is blessed with unpredictable and unbelievable discoveries that reveal the wonders of our world and our universe.

Shocking and even unbelievable, these facts describe the way the natural world is amazing and even unimaginable as far from the mysteries of the human body to the limits of space. The following are 15 incredible facts in science which will not only educate, but will also astonish.

Before understanding the facts about science, also have a look at the science project for kids, rocks and minerals .

1. The Human Stomach Can Dissolve Razor Blades

Yes, it is true that the human stomach can dissolve the razor blades. Gastric acid is very aggressive and capable of corroding metals.

Any swallowed blade would be sharp and dangerous, and any internal severe injury would occur before any corrosion could occur visibly.

2. Babies Have More Bone than Adults

Approximately 300 bones are present in babies, most of them being cartilage. These bones develop to form tougher structures by fusing some of these bones.

By the time a human being reaches the age of an adult, there are 206 bones present in the skeleton. This kind of combination makes them flexible at birth and ensures their growth, and also offers a powerful structure of movement and physical activity to adults.

3. The Human Body Has more Bacteria than Human Cells

The human body is home to trillions of bacteria. There has been recent research that showed that the number of bacterial cells within the human body is just as many as our own, about 30 trillion of human cells and 38 trillion of bacterial cells.

These microbes live on the skin, on the intestines and in other organs of the body and play a part in digestion, immunity and health of the organism. They are microscopic, but they play extremely vital functions in keeping our bodies in check and maintaining a fine balance in our biological mechanisms.

4. A Day on Venus is Longer than a Year on Venus

Venus is a weirdo since its rotation about its axis is very slow, and it takes the planet about 243 days for the Earth to revolve. It, however, takes only 225 days on Earth to complete one orbit around the Sun.

This means that a complete year of Venus needs more time than one day on Earth; hence, it is one of the bizarre rotations in the solar system.

5. Lightning is Hotter than the Surface of the Sun

Lightning is a huge discharge of electric energy able to heat to approximately 30,000 Kelvin, or five times hotter than the surface of the Sun, 5,500 Kelvin.

This heat causes the air to expand, and the noise that we hear is that of this expansion. Lightning is also one of the most astonishing and dangerous natural phenomena on the Planet, as it is unbelievable in its power and heat.

6. Bananas Are Radioactive

Potassium-40 is an isotope with a radioactive element that emits meagre amounts of radiation and is also naturally present in bananas. This makes bananas somewhat radioactive, although this does not pose any harm to a human being when consumed in an average manner.

The potassium that is believed to be important to our health is the source of the radiation, and that is what causes natural elements in our food, like potassium, to have surprising scientific properties without posing a real danger to our health.

7. The Human Brain Generates Enough Electricity to Power a Lightbulb

The neurons are constantly generating electric impulses as the human brain is in communication. The overall energy production is estimated to be around 20 watts, and that is sufficient to turn on a small lamp.

Thinking, learning, memory and bodily functions are based on this electrical activity. We can not directly tap this energy, but it proves the amazing complexity and strength of the biological processes of the human brain.

This fact also inspires curiosity in young kids to explore science experiments .

8. Honey Never Spoils

Honey contains natural preservatives, such as low water content, high acidity, which inhibit the growth of bacteria and fungi. Archaeologists have discovered that there were honey pots in ancient tombs more than 3,000 years old that are still edible. 

The chemical content guarantees it lasts long and makes it a natural sweetener that can never go out of style, provided it is well preserved and, of course, not touched by the contemporary preservatives.

9. The Universe Has No Centre

The universe is growing in all directions at the same pace, meaning that it does not have a centre. The galaxies are moving away, and every space appears to contain the centre of the world itself.

This is the main principle in cosmology, and it goes against any intuitive concept of space and further emphasises that the cosmos is very big, infinite and complex.

10. Blue Blood and Three Hearts of the Octopuses

The octopuses have three hearts, two of which force the blood into the gills and the other into the whole body. They also possess a copper-based molecule referred to as hemocyanin that delivers oxygen to their blood, therefore giving it a blue look.

This is an adaptation that helps them to survive in environments that are low in oxygen levels in the deep ocean. Unlike human beings, who rely on haemoglobin containing iron to transport oxygen to the blood, the blue blood in octopuses plays an important role in their metabolism.

11. You Can’t Taste Food without Saliva

Salivation is important in the process of food tasting because various molecules of flavours are dissolved by the saliva, and it is in the taste buds of the tongue that these flavours are identified.

Without saliva, the chemical properties of food will not have the capacity to touch the sense receptors; therefore, no power of being able to taste flavours fully. Saliva is also used to protect the mouth, and its significance in tasting and general well-being in the mouth is revealed.

12. Helium Works Against Gravity

The mixture of the atomic mass of the helium is so low that it renders it lighter than air. Under the pressure of being inflated in balloons, it expels the air that is heavier, consequently making the balloon rise. This property is also pertinent to helium in scientific tests and in industries.

It is dilute and inert, and this adds some interesting phenomena whereby gases will behave in such a manner that it seems like they are going against gravity.

13. Lightning Can Strike Twice

On the contrary, one may be struck at the same site more than once by lightning. Skyscrapers and towers are examples of high-rise buildings that are prone to attacks on a regular basis.

Lightning follows the path of least resistance, and multiple hits can occur within minutes or seconds. The reason behind this is that electricity is unpredictable in nature and may cause accidents, which require precautions against lightning.

14. Galaxies are Enormous Cosmic Webs

Galaxies are not randomly distributed, but they are connected by big filaments of dark matter and gas to form a cosmic web of immense size. It is built of billions of light-years, and the galaxies are stranded together by filaments and spaced apart by large vacuums.

The cosmic web confirms that matter in the universe has a very intricate structure and reveals the hidden patterns of such a realm as space.

For Class 4 students, these fun science experiments are perfect for exploring.

15. Venus Spins Backwards

Venus does not behave like the rest of the planets; it does the opposite rotation, which is referred to as retrograde rotation. This causes the Sun to rise in the west and to set to the east.

All that leads to Venus being an exceptional planet because of its slowness in rotating backwards, which, combined with its dense atmosphere, makes the climate on the planet the most hostile, with things not being so short, hot weather and the sheer weight of the atmosphere that surrounds it.

Conclusion

Science is a world where incredible phenomena that are, on most occasions, surprising are happening and which enlarge our knowledge of life, nature and the universe.

These shocking facts teach us how complicated and unbelievable the surrounding world is, the human body and its possibilities, planets and galaxies. Their knowledge leaves one curious, thinking and innovative.

After reading all these scientific mysteries, we then realise how much we are grateful to the natural world and all the possibilities that keep being discovered by science.
