There are a lot of scientific facts worth mentioning and knowing. However, a vast majority of people want to avoid the hassle of reading, researching, and looking for these valuable pieces of information. We are here to bring you a list of interesting scientific facts you might never have never heard until now. It’s always useful to have some additional knowledge about your environment and the world in general. Without further ado, here are some interesting scientific facts you might not know.
Human DNA could be stretched from the Sun to Pluto 17 times
This mind-blowing fact is actually true. There is enough DNA in average human’s body to stretch from Sun to Pluto about 17 times. How is this possible? It’s pretty simple. The genetic code in human cells contains 23 DNA molecules which have anything from 500000 up to 2.5 million nucleotide pairs.
When uncoiled, these cells are, on average, 5 centimeters long. Because we have around 37 trillion cells, the uncoiled length of these cells would result in a total length of 2×10^14, or in other words, enough for 17 trips to Pluto and back.
We carry ten times more bacteria cells than human cells
It’s funny if you think about how compulsive we are about washing our hands, showering, caution when someone sneezes, etc. In reality, we have more than ten times more bacteria in our bodies than regular human cells. However, don’t get frightened by this fact, most of the bacteria are helpful and useful in fighting various disease. In fact, we wouldn’t be able to survive without them. Bacteria produce a chemical which helps us harness the valuable elements from the food we eat.
Also, various types of stomach bacteria are essential for maintaining immunity and optimal levels of digestion.
The Great Barrier Reef is the largest living thing on Earth
When asked this question, people often think of elephants, whales, dinosaurs, and other gigantic wildlife that once walked the Earth. However, most of those guesses are wrong. No one would ever think that the largest living structure on Earth is The Great Barrier Reef. It’s a system of coral reefs consisting a huge number of corals and soft-body animals linked by tissue.
This system has about 3000 reefs and 900 coral islands. It’s more than 2000km long, and it covers a surface of 350000 square kilometers. However, the alarming thing is that this coral system is slowly dying due to pollution, global climate change, and man-induced disasters.
The average person walks five times around the world
If we take an average estimation of 7500 steps per day and an average lifetime of 80 years, it results in around 216 million steps. By using simple math, we can calculate that an average person walks around 110 thousand miles in their lifetime. Considering that the circumference of the Earth is about 24 thousand miles, an average human will walk five times around the world in their lifetime.
