Carl Sagan's Pale Blue Dot

That's here.
That's home.
That's us.

On it, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.

The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast, cosmic arena.

Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot.

Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner.

How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

Our posturing’s, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light.

Our planet is a lonely speck in the great, enveloping cosmic dark.

In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known so far to harbor life.

There is nowhere else, at least in the near future, to which our species could migrate.

Visit, yes.
Settle, not yet.

Like it or not, for the moment, the Earth is where we make our stand.

It has been said that astronomy is a humbling and character-building experience.

There is perhaps no better demonstration of the folly of human conceits than this distant image
.
To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we've ever known.

The Cosmic Address

Before we learn about Cosmic Address, It’s important to know what cosmos is. Cosmos in easy word is everything that there is or there ever will be in existence. For instance let’s talk about postal address, the way we define our postal address is by layers / levels through which we could be located. House Number à Street Name/Number à Locality/Neighbourhood à City à State/Province à Country, and that’s where we end our postal address at country we don’t go writing our continent or Earth/Globe. But when we speak of cosmic address the scale turns to new heights where our house number becomes the planet Earth and the Earth/Globe becomes Cosmos.

♦ Earth (House Number) 

The Planet where we or anybody we've ever know live. Home to all our continents & countries, civilizations & governments.

♦ Solar System (Street Address) 

The system that house our planet surrounded by celestial bodies. The Sun is at its near centre and all planets revolve around it

♦ Milky Way Galaxy (Locality / Neighborhood)

The galaxy that house a group of such solar systems. With what is believed to be a dark matter at the centre of it which is responsible for gravitational activity to keep the systems bound in a motion.

♦ Local Group (City) 

The group of such galaxies is called “The local Group”. Imagine localities in a city it's just like that but on a much much higher scale.

♦ Virgo Super Cluster (State / Province) 

These local groups combine and form a Virgo Super Cluster. Every cluster has a lot of local groups which has many galaxies who have enormous amount of solar systems with uncountable Suns Planets and Stars.

♦ Observable Universe (Country) 

This is the last line know to us till now and so we call it observable universe. This is the collection of all super cluster that we currently know of.


♦ Cosmos 

We are yet to discover what in our term could be called continent and globe and who know there might even be a lot more layers. So, we call it all Cosmos and this is our Cosmic Address.
Comparing Microorganism to Human would be a rational comparison on relative scale to understand the comparison of Planet Earth to Cosmos.

What Is Science....!!!!!


What Is Science? Is it just a word that describes all the text that a book carry? Maybe it's a stuff what all those "so called" great scientists have ever written about? oh wait! it's the pure waste of life cause millions of those scientists devoted their life and accomplished nothing, all they got was failures and history doesn't even remember them.

"Give kid a book, and you change the world. In a way, even the universe." 

 Gandhi once said "Literacy is not the end of education nor even the beginning." That's what science is,it's education. Educating an year old kid on how to fight gravity and stand, how to use friction to walk and run,how to vibrate your vocal cord and make a sensible sound that a human can understand. Science is a religion without God or Messenger or saints or sinner. Science is freedom, freedom to challenge authority,freedom to make new rules instead of following older. Science is everything there is , ever was and ever will be. who we are humans or living beings or almighty ruler of the planet or even the universe ? we are nothing but Star Dust.

It is true many millions have died for science and we don't even know their names but none of them ever wasted their life. They all had their part and contribution to the society we live in. Einstein wouldn't have been who he was if it wasn't for the scientist before him. Science is too big for a single man to pursue on his own. Every so called FAILED scientist didn't died in vain, they told the world "we already walked this path and came back empty handed.Don't go this way find you will not find anything search another approach". Imagine would Einstein would have done all those thing he did if he had to do it from scratch one ? Every single failure revealed a truth a theory. Those failed scientist didn't failed once they just didn't had enough life to see their work through. 

The best thing about science is that you don't have to perfect, you don't have to have all the answers, you can stand on a ground where you can proudly say that its beyond my understanding. All science listens and bows to is reason. Science is one of the rarest and yet cheapest commodity that gives us certainty of things in this uncertain world.There was a time when great minds of world believed that the smallest particle is atom until came along a new theory of subatomic particles. Hell ! there was a time when people believed that sun revolves around the earth. Even today we speak of SUN RISING do we not? But with time and knowledge everything changed or to be more accurate everything evolved.

Science is a path of mysteries one clue leading up to another, it's the quest the thirst to find the reasons and explanations of how things work, how they behave what could the future effects of the actions,how we came to be where we are is their another world? if it is how similar would it be to ours where could be in this cosmos ? 


Science is script of questions that are yet to be answered, at the same time it is  the explanations of the things known to us.
Once you get the idea of science  you'll know that i could go on writing thousands of page and yet i wouldn't be able to describe all it's aspects

I remember few lines from couple of Shows , see if it makes sense ...
Knowledge is power, and power resides where we believe, it's like a game of shadows and even a small man can cast a very big shadow. And so it's said 
" Give Kid A Book And You Change The World "
