Hi dear ones !!

whats a superpower nation …………..                   

A superpower is a state with a leading position in the international system and the ability to influence events and its own interests and project power on a worldwide scale to protect those interests; it is traditionally considered to be one step higher than a great power.

There have been attempts to apply the term superpower retrospectively, and sometimes very loosely, to a variety of past entities such as 

Ancient Hindu or Bharat( Indian Sub-continent), Ancient Egypt, Ancient Greece, China, the Persian Empire, the Ottoman Empire, the Roman Empire, the Mongol Empire, Portuguese Empire, the Spanish Empire, France, the Dutch Republic and the British Empire.

Potential Superpowers

Academics and other qualified commentators sometimes identify potential superpowers thought to have a strong likelihood of being recognized as superpowers in the 21st century.    

Due to their large markets, growing military strength, and economic potential and influence in international affairs, the Federative Republic of Brazil, the People’s Republic of China, the European Union, the Republic of India, and the Russian Federation, are among the powers which are most often cited as having the ability to influence future world politics and reach the status of superpower in the 21st century.

But…………..                      

The notion of a “superpower” is increasingly anachronistic in the 21st century as increased global integration and interdependence makes the projection of a superpower hard but not impossible.

hi dear ones !!

We are part of universe.                                   

i and you watched movie avatar.and as i was, you also have thought of the possibility to go to other planet with some life.

Here is some data for you.

The statitistics

1) The number of galaxies. An estimated 50 billion galaxies are visible with modern telescopes and the total number in the universe must surely exceed this number by a huge factor, but we will be conservative and simply double it. That’s 100,000,000,000 galaxies in the universe.   

2) The number of stars in an average galaxy. As many as hundreds of billions in each galaxy.

Lets call it just 100 billion.

That’s 100,000,000,000 stars per galaxy.

3)The number of stars in the universe.      

So the total number of stars in the universe is roughly 100 billion x 100 billion.

That’s 10,000,000,000,000,000,000,000 stars, 10 thousand, billion, billion. Properly known as 10 sextillion. And that’s a very conservative estimate.

4) The number of stars that have planetary systems. The original extra-solar system planet hunting technology dictated that a star needed to be to close to us for a planet to be detected, usually by the stars ‘wobble’. Better technology that allows us to measure the dimming of a stars brightness when a planet crosses its disk has now revolutionised planet hunting and new planets are being discovered at an ever increasing rate. So far (August 2003) around 100 have been discovered so we have very little data to work on for this estimate. Even so, most cosmologists believe that planetary formation around a star is quite common place. For the sake of argument let us say it’s not and rate it at only one in a million and only one planet in each system, as we want a conservative estimate, not an exaggerated one. That calculation results in:                           

10,000,000,000,000,000 planets in the universe. Ten million, billion, as a conservative estimate.

5) The number planets capable of supporting life. Let’s assume that this is very rare among planets and rate it at only one in a million. Simple division results in:

10,000,000,000 planets in the universe capable of producing life. Ten billion!                                  

But do not let this data discourage you.

after all we are humans and we keep our hope alive.        

So let us just keep searching for living beings.
