Have u ever thought? : Yes Sometimes I Do!

Why is the sky so blue?
- because molecules in the air scatter blue light from the sun more than they scatter red light.
Water so much wet?
- Water is not wet, but a bit sticky. All fluids have what we call surface tension, a tendency to stick to things even itself. You have probably notice how little objects can be stuck to the surface of water and not sink. Certain insects walk on water using this phenomina. So when you get water on yourself it kind of sticks to you. You can't shake it off, you have it wipe it away or evaporate it. So you think your skin is wet because it sticks on it.
Why is the earth round?
-The rotation of the earth adds centrifugal effects, which cause the earth to bulge slightly at its equator and flatten slightly at its poles.

Why is  silk so soft?
- Because silk fiber, by nature, is soft - because of its smooth surfaces.
Why is the fire so warm?
- Burning is an Oxidation process. Oxidations give off heat because electrons in the product molecules are shifted toward the electronegative atoms, and the molecules are more stable as a result.The change in energy is resulted as HEAT. Therefore, different compounds, when burnt, produce different amount of heat.
Why is 2+2 not five?
- five and the operator '+' are not defined to represent the sum 2 + 2 equals five.

Why are trees getting so less?
- Because of increasing human population and deforestration.
Why is the spring so short?
- The length of a spring is determined by its use and purpose. Longer springs can also be created. In fact, we can create a spring of any length physically possible.
Why don't we have two moons?
- Earth has only one moon, by creation. However, other planets have more than one moon.

Why is there war all over the world?
- Most wars result from a combination of causes. Three of the most common causes are conflicts over resources, clashing ideologies, and struggles over power.
why is blood shed all over?
- Blood Shed occours when someone is put to death, usually intentionally or knowingly. Adult ladies also undergo through blood shed during menstruation.
Why is there borders every where?
- Border is defined as 'a line or relatively narrow space that marks the outermost bound of something'. Border is used in different context: e.g. border of communication, geography, clothes, photo etc. 

Have you thought about this ever?
- It is said that human mind keeps thinking 90% of its time. However, the content of the thought varies with age, environment and mental state. E.g., kids are more curious with such natural mysteries while, adults thinks on sex, success and work.
Have you thought why is it like this?
- Personally, I do have. But not all people think this way.
Have you thought If not than think it now!
- Your suggestion is considered seriously.

Why do rivers flow?
- Normally rivers (water or in general any liquid) has the natural tendency to level its surface (because of gravity). So it flows in slope. However, by confining it in an closed area, it can be prevented from flowing.
Why do we have light?
- In fact we - human being, do not have light. Mainly there are three resources of lights : sun, oxidation process (burning), friction generated (electricity etc.).
Why do snow fall?
- Snow falls in cold environment because of gravity. Since snow's density is higher than that of air's so it can not float in air.

Why do friends get lost?
- We loose somebody either by not maintaining contact with them or if they die.
Why do stars fall off?
- Those objects are called meteors. A meteor is a small piece of debris (or meteoroid) that burns up as it enters the earth's atmosphere and is seen by observers as a momentary streak of light. Commonly known as "shooting," or "falling," stars, these objects vary in size from mere dust specks to small bits of rock and metal with masses typically less than one gram (weight of 0.04 oz.). A meteoroid enters the atmosphere at very high speeds (between 10 and 70 kilometers a second, or 20,000 to 150,000 miles an hour) that cause the surface of the object to heat up via friction. The surface of the meteoroid vaporizes and leaves high-temperature atoms, as well as heated molecules, in its wake. The superheated meteor atoms and molecules then glow in a process that is similar to a fluorescent bulb. Thus, when you see a falling star, a piece of debris the size of a grain of sand has been converted into heat, a visible streak of light and atom-size dust particles.
Why do clouds give lightning?
- Lightning is a large discharge of static electricity that clouds get due to friction.

Have you thought about this ever?
- Most people, specially kids are curious in nature. We all have such thought once in our life time.
Have you thought why is it like this?
- Sometimes we do think for the reasons as well.
Have you thought If not that think it now!
- Your advice is noted.

Why don't we hear silence
- Hearing involves the behavior of the mechanical apparatus and the neurological processing of the information acquired. Any vibration produces a weves that, once strickes on our airdrum, produces a signal which our brain processes and we hear it. Silence means no vibration, and we can not hear it is not producing any waves.
And why don't we see the air
- Air is thin and HIGHLY transparent and this property makes it invisible.
Have you thought Ever before why does this happen?
- Sometimes as a kid, I used to ..
