Part 13-Who Speaks For Earth?
Since time immemorial our ancestors started thinking about life and death...blessing and curse...They nourished a passion for intelligence.From that they developed tools to survive,prosper and to search other civilizations.
This passion helped them to develop nuclear weapons.But after a nuclear war there will be no more big questions..no more answers..no more voyages to stars..no more song from the earth..
In 'Who speaks For Earth',Carl Sagan points out the threats posed by nuclear weapons."Every thinking person knows about nuclear war and its effects.Every technological naton plans it.Everyone knows about its madness.But every country has an excuse",he says.
Every year a trillion dollar is spend for wars.Nuclear weapons speak for natons.Who speaks for earth?Who speaks for human species?
The documentary visualises the flourish of human civilization-the story of Greeks,Romans,Alexandria and the fate of the great library in Alexandria.History is full of people who feared ignorance.The lust for knowledge and power decided the destiny of civilizations.
To instill the awefulness of of the destruction due to wars,the beginning of the universe is explained.The clouds of Hydrogen gas formed due to the Big Bang formed the galaxies.The ash formed by the fusion of Hydrogen became the raw material for life.Life evolved gradually..
We are creatures of 'cosmos ' who are curious about our origin and relation with the universe.There may be different civilizations.But we are one species.
'The sacred truth of science is that there is no sacred truth' Science is the best tool to explore the cosmos.'Who speaks for Earth' underlines that our duty is to wonder about the cosmos..not to fight eachother.
The documentary is written by Carl Sagan,Aan Druyan and Steven Soter.The series is directed by Adrian Malone.

COSMOS
part 9 -Lives Of The Stars
We are made of the star's elements! Carl Sagan's Life Of The Stars reveals the mystery of the Cosmos.Its vastness...its majesty...
The beauty of the natural world is made of 92 chemically distinct elements .A change in the number of protons and neutrons forms a new element.
An atom is the key to the puzzle of the universe.Its just an empty space with electrons revolving around the nucleus-a small model of solar system.With similar forces working on it.Its gravitational force in solar system,but attractive and nuclear forces in an atom.
'Lives Of Stars' predicts the fate of our sun and ofcourse 'our fate'.The documentary foretells the death of earth after 500 years.Then the 'red gaint' of our sun will engulf neighbouring planets including our earth.The ash from todays fusion will be the fuel for the sun in its final days.
The red gaints will form supernovas.The star will become a single massive atomic nucleus.Then the star will turn to a 'black hole' where even light is imprisoned.
Carl Sagan assumes that a black hole leads to another reality-another universe.'The Cosmos is riding The Gravity Express'.

MYTH BUSTERS
Man's anxiety to chase the secret behind explosions is dissolved in his blood.Explosions are not new for life.The starting point of life and universe is an explosion-a Big Bang! The reason for the constant eagerness about explosions may be this fact.
Myth Busters gives a brave effort to reveal the mysteries behind some explosions.The documentary unviels the puzzle behind gasoline explosions,bursts due to implants and exploding CD's.
The truth is found out by experimenting each assumption.The critical examination of the assumptions gives a clear conclusion.
Assumptions may not be the truth.But they can show the door to truth.Science is the chase after assumptions!
The documentary is hosted by Tamie Hyneman and Adam Savage and is edited by Philippa Rowlands.The production is by Beyond Production Pvt Ltd for Discovery Channel
