8 Amazing Facts From The World of Science
Science is the most amazing thing in this universe. It is beyond our imagination, and beyond all magic tricks, you might have seen round you. Here are a few astonishing things that are known to the world because of advances made by the science.
- New Born Babies have about 100 additional bones than a grown person.
When babies are born, they have around 300 bones, with cartilage, a connective tissue, between a lot of them. This added flexibility helps a child come out through the birth canal. It also helps with the speedy growth of the baby. While growing, many bones join, which leads to 206 bones in the body.
- A photon takes 40,000 years to reach from core of the sun to its outer part, but merely 8 minutes to reach on earth.
The distance between core and surface of the sub is around 696,000 kilometres and it takes photons 40,000 years to reach to the surface from the core of the sun, where it can go out into space. In other words, the light energy that touches us today was created maybe thousands or millions of years back.
- Amazon Rainforest generates around 20% of the Earth’s total oxygen level in atmosphere.
Earth’s atmosphere contains 78 % Nitrogen and 21% Oxygen, with other gases existing in very small amounts. The majority of living beings require oxygen to stay alive. Spread over 2.1 million square miles, the Amazon forest produces a substantial amount of the Earth’s oxygen, while absorbing huge amount of carbon dioxide as well.
- A teaspoon filled with neutron star could weigh up to 6 billion tons
Astronomers calculate the overwhelmingly masses of stars or galaxies in solar masses, where one solar mass means the mass of the sun, that is approximately 1.99 × 1030 kilograms. An usual neutron star have a mass of around 3 solar masses, which is jam-packed into a ball with a radius of about only 6.2 miles, making it one of the densest known matter of the universe.
- Spread over 2300 kilometres of length, The Great Barrier Reef is the biggest ecosystem on Earth.
The Great Barrier Reef is the largest coral reef system of the world. It contains above 2,900 distinct reefs and 900 islands extending for over 2,300 kilometres over an expanse of about 344,400 square kilometres. It is the largest living organism on Earth and the only thing discernible from space.
- A person walk the distance equal to the 5 times that of around the world in a lifetime.
An average person takes about 7,500 steps every day. So a person at the age of 80 years would have walked around 216,262,500 steps in 80 years of his or her life. Based on estimations and calculations, an regular person with the average pace would have walked around 110,000 miles in the 80 years of his or her life, which is the equal of walking approximately 5 times around the Earth.
- It takes 60 seconds for a single blood cell to make a complete round of the body
An average healthy human body contain approximately 5 litres of blood and around 70 ml of blood is ejected by heart with each beat. That is, a healthy heart beats approximately 70 times per minute. So, if you calculate the quantity of blood that is pumped by a healthy human heart in 60 seconds, the result will be about 4900 ml of blood per minute, which is almost the total amount of blood in a human body.
- In about 2.3 billion years, life will stop existing on the Earth.
Though it is still too far, scientists predict that in 2.3 billion years, the earth will be too hot for the life to survive here. In upcoming millions of years, the temperature of the sun will rise steadily. It will get brighter and hotter with time, and in just over 2 billion years, earth will be hot enough to vaporize the oceans, and that will end the life as well.
