What if we can contact Aliens ? by Physics Advocate/advguruji

Before the beginning, first discuss about aliens.
Aliens are those creatures which do not belong to our world.
Now a question comes to your mind. Can we contact aliens? The answer is most probably NO.
But why?
Because first we have to find that type of planets (or natural satellites) which can support life. This is not an easy task. Also, a planet which can support life is not enough.

Why?
Because life can exist in various forms. One form is unicellular organisms. For example, in our solar system it is believed that Titan (Saturn's moon) can support unicellular life. But the disadvantage is we cannot contact them by our communication methods. But yes, there is a high possibility in future that a rover mission can take some samples of the unicellular or may be small multicellular organisms and send the data to Earth.

Now comes the interesting part. If a planet is supporting complex life like animals, plants or even species like us (humans), then also there are very very low chances for us to contact them.

Why?
Believe it or not, humans are very smart. For example, if aliens from any part of our universe tried to contact us about 1,000 years ago, then there was not a single chance from our side to identify their message at that time (as we were not smart enough that time).
So may be complex life is present somewhere today but we can't say it is smart enough to contact us, or maybe it will never become intelligent like us.

Now comes the main question. What if we can contact aliens today?
The answer is if they behave friendly towards us, then there are numerous possibilities for both sides to learn new things from each other.
Concepts like Astronomy, Biology, Geography will be in the top list of knowledge exchange. May be after few centuries both sides will become capable enough to use each other's natural resources for their needs, who knows...

But, there is a big but. Maybe the aliens are not friendly towards us. If this happens, then there will be a huge problem or maybe huge problems.

Maybe an interstellar war will start. If we got an upper hand on them only then we will survive after the deadly interstellar war. Otherwise, we have to face the consequences.

But HOLD ON-HOLD ON... don't worry about the war. Maybe it will not happen too early or maybe there are no intelligent aliens in our universe.

Why living on Mars will be worse than we think?

Wind Energy | wind generators | advantages and disadvantages of Wind Energy by - advguruji

Moving air is called wind. Wind has energy. The energy possessed by wind is due to its high speed. So we can say the wind possesses kinetic energy . It is the kinetic energy of wind which is utilized for doing work. Solar energy or sun's energy is responsible for the blowing of wind, due to the uneven heating of earth by the sun in different regions. Now let's discuss about what is a wind mill. Wind mill The energy of wind is harnessed by using a windmill. A windmill consists of big sized table fan like blades which are fixed over the top of a tall pole in such a way that they are free to rotate when the fast moving wind strikes on the blades of the windmill. It makes the blades rotate continuously. The rotatory motion of the windmill is then used to do Mechanical work through a shaft connected to the rotating blades. The traditional use of wind energy has now been modified by the improvement in technology to generate electricity through wind powered generators. Wind Generator ...
