We learn about some awesome Science on daily basis and mostly in high school - like Einstein's theory of relativity, the periodic table and DNA replication. The knowledge we pick up lays the foundation for all the amazing things we study. But science certainly does not end in high school, and it takes your learning to the next level once things get really interesting.
Without any particular order, here are some Amazing Intresting Science Facts Nobody Knows that we did not learn in high school, but I wish this current education system in India should teach that and same applies for the world . But When I am there no worries . Just read the Intresting And Amazing "general science facts" That Nobody Knows .
1. The Eiffel Tower can be 15 cm taller during the summer
When an object is heated, its particles move very more than its cool . And take on a large volume - this is known as thermal expansion. On the other hand, a decrease in temperature causes it to Contract. The level of mercury inside the thermometer, for example, rises and falls as the volume of mercury changes with the current temperature. This effect is most noticeable in gases but comes from liquids and solids such as metal. For this reason, large structures such as bridges are constructed with elastic joints that allow one way to expand and contract without causing damage.
2. Water can boil and freeze at the same time

3. A teaspoonful of neutron star would weigh 6 billion tons
4. An egg looks like a crazy jellyfish underwater

A broken egg on the ground can cause great violence, but 18 meters (60 meters) below the surface of the ocean, the pressure on the egg is 2.8 times greater, and it holds it together like an invisible egg shell.
5. Polar bears are nearly undetectable by infrared cameras
6. This is what happens when a black hole swallows a star

As the star enters the black hole, a large plasma jet is released, covering centuries of light. "When a star is torn apart by the gravitational pull of a black hole, half of the star's remains fall into a black hole, while the other part is released at high speed," explains Johns Hopkins University researcher Suvi Gezari.
7. If you took out all the empty space in our atoms, the human race could fit in the volume of a sugar cube
The atoms that make up the world around us seem solid but are actually more than 99.99999 percent of the empty space. An atom has a tiny, dense cell surrounded by a cloud of electrons, scattered across a large area evenly. This is because even as particles, electrons act like waves. Electrons can be formed only when the particles and hulls of these waves combine well. And instead of being in one place, each electron space differs in a certain range of possibilities - the orbital. Thus they settled in a large area.
8.If you spin a ball as you drop it, it flies

I mean, it's really flying. It is the result of the action of the Magnus, which occurs when the air on the front side of a rotating object moves in the same direction as its spin, meaning that it is pulled along and the object is pushed backwards. Meanwhile, the air on one side of the ball goes to the other side, so the air flow is different.
Watch Veritasium explain it with practical .
9. A flea can accelerate faster than the Space Shuttle
Jumping flea reaches a staggering height of about eight inches (three inches) in milli seconds. Acceleration is the change in the speed of matter over time, usually measured in ‘g’s, by one g equal to the speed caused by gravity on Earth (9.8 / 32.2 meters per square second). Fleas experience 100 g, while the Space Shuttle peaked at around 5 g. The secret of the fleas is an extended rubber-like protein that allows it to store and release energy as a spring.
10. In 2.3 billion years it will be too hot for life to exist on Earth
For hundreds of millions of years to come, the sun will continue to shine with increasing heat and heat. In just over two billion years, temperatures will be high enough to deplete our oceans, making life on Earth impossible. Our planet will be a vast desert like Mars today. As it grows into a red giant over the next few billion years, scientists predict that the Sun will eventually completely cover the Earth, spelling out the definite end of our planet.
11. Hawaii moves 7.5cm closer to Alaska every year
The Earth's crust is divided into large sections called tectonic plates. These plates are constantly moving, driven by the currents of the Earth's upper garment. The hot, very small rock rises before cooling off and sinks, forming circular circles that act as large conveyor belts, slowly moving the tectonic plates above them. Hawaii sits in the middle of the Pacific Plate, which runs slowly northwest toward the North American Plate, and then back to Alaska. The speed of the plates is comparable to the speed at which our nails grow.
12. Chalk is made from trillions of microscopic plankton fossils
The tiny single-celled algae called coccolithophores have been in the Earth's ocean for some 200 million years. Unlike other seaweeds, they surround small plates of calcite (coccoliths). Just under 100 million years ago, conditions were right for coccolithophores to accumulate in a dense area that clings to the sea floor in white splendor. As more soil formed on the surface, pressure compressed the coccoliths to form rock formations, creating cracking deposits like the white rocks of Dover. Coccolithophores is one of the many prehistoric species that have been extinct, but how do we know how old they are? Over time, the rock forms flat layers, leaving old rocks at the bottom and small stones near the top. By studying the type of rock where fossils are found, palaeontologists can estimate their age. Carbon emissions measure the age of fossils in particular, based on the decay rate of radioactive substances such as carbon-14.
13 .Animals use Earth’s magnetic field for orientation
Lost land animals may not be able to find their way home, but marine animals are possible. According to the U.S. The Geological Survey (USGS), "there is evidence that other animals, such as sea turtles and salmon, have the ability to sense Earth's magnetic field and to use this concept in navigation."
14.There are more trees on Earth than stars in our galaxy
It is Hard to Believe But it's true for now atleast but it can change because every moment new star is building and ending but trees are decreasing on earth every year .NASA experts believe there could be anywhere from 100 billion to 400 billion stars in the Milky Way galaxy, reports Snopes. However, a 2015 paper published in the journal Nature estimated that the number of worldwide was very high: 3.04 trillion.
15.Bananas are radioactive
In one of our intresting and amazing science facts ,bananas contain potassium, and as potassium decomposes, it produces less radiation. But this is one of the great truths of science that you do not need to worry about. You will need to eat 10,000,000 bananas at a time to die with radiation poisoning, Forbes reports
