Ans. You must be aware of the fact that the jet engines of any commercial airplane are capable of sucking an adult if he/she passes before it. The human body cuts into pieces and a red soup like thing drains out from the back of the jet engine. To avoid this type of accident, and to inform the workers whether the engine is ON or not, a curl is drawn in the front which when rotates seems like a spinning whirlpool. It also helps in keeping out birds.

2.Why lights in the passenger cabin dims during take-off and landing?


Ans. If you have ever been in an airplane, you must have observed that the lights inside the passenger cabin are dimmed during take-off and landing, at night. This is because of the fact that 80% of air accidents occur during take-off and landing. And our eyes might take about 10 mins to adapt in the darkness after a sudden light-off condition. To aid the chances of survival of the passengers in case of emergency/accident, the lights are dimmed to let the eyes adapt to darkness beforehand. Even a few seconds can decide your survival in emergency.

3.Why the fuel is stored inside the wings of the airplane?


Ans. A passenger jet is a way heavier than a car and fuel is also a major part of it. If most of its weight is concentrated in the fuselage(body) of the plane, the wings might bend or break. To avoid the bending of the wing, the weight is distributed all over the plane by storing the fuel inside the wings.

4.Why foods in airplane taste bad?


Ans. If you have ever been in a plane, the most annoying experience you probably had was the food. Trust me it's not the fault of the airline but the environment inside the plane makes the food taste so bad. The dry recycled air inside the cabin makes the food taste dull and lack smell. The sweet flavor tastes less sweet and salty taste increases. These all make your food bland.

5.Why do planes leave trails in the sky?


And. You must have noticed that the air you exhale in winter season seems like a smoke. And we used to wonder how it happened during childhood. Fuels also emit a considerable amount of water vapor when these burn. The same condition arises when the hot gases + water vapor mix with the very cold atmosphere at high altitude, leaving white smoky trails

3 astonishing theories about the universe

There are a number of cosmological models and theories you might have heard about. Many of them answer most of the questions but not all. The curiosity and the quest to find the answers often result in more theories. Here we present 3 astonishing cosmological models about the universe. After all these are still theories as none has been proved yet. 1.White Holes You must have heard about the Black Hole ( click here ). A black hole is the result of a star which has died, creating a highly dense and massive body which sucks in light and all other matter surrounding it. But where do all these matter and energy go? White holes are just opposite to black holes. Instead of sucking in, they spit out everything what the blackhole absorbs. It is an area in spacetime which couldn't take anything in but throw it out into its surrounding. This was an hypothetical model created using the concept of relativity. If one will be ever found in future, it might disprove many laws of ...

String Theory. Know on the go.

String theory  We rely on string theory to understand and to combine the quantum theory and the gravity. As the name suggests, whole theory is based on string like structures. The one dimensional objects which only have length. The lies and move through background spacetime. The advance version of string theory i.e. superstring theory is considered as THEORY OF EVERYTHING . So what string theory exactly is ??? Strings are one dimensional objects that contain energy and by there flow, one can say that energy is moving. Suppose we take a long thread and tie a knot, it will became a loop, similarly strings are joined to make a loop known as Heterotic string. These are 5 independent strings theories, telling the same thing but in different dimensions. Combination of all the 5 string theories is known as S uperstring theory . Let us see how  it works... Consider a violin, the strings attached to it, are producing waves, which are the source of energy. Havin...

GOD! or SCIENCE?

One can question the existence of the God, the almighty, but can't question the belief of the people. The most controversial topic of current time and the never ending debate between religion and science- THE EXISTENCE OF THE GOD. We all must have heard one or more of the words: God, Allah, Bhagwan, the Almighty, Ishwar etc since the day we stepped into this massive universe. These all point to the same power, the supreme one. The power that drives the universe, that drives you and me and every other creature. The force that exists within each and every elementary particle. Some people having keen interest to question all the things around them, known as Scientist, believe what they see and what get through various complex equations. And 'the existence of the God' too didn't remain untouched. Perhaps, there is nothing wrong in finding what's hidden inside the nature's womb. It just get us closer to the mighty universe. That's what a scientist alw...
