TIME THE FOURTH DIMENTION

TIME THE FOURTH DIMENTION

Few days back  when i woke up i experienced that my head was spinning vigoresly.
I caught hold of my bed I thought i am travelling through a wormhole. Now i will land in another dimention…i had read…
I screamed my family came to help. I landed at doctors clinic, he pronounced that it was cervical spondylosis. I thanked almighty that i got well. My mind was thinking of the wormholes, time travel the dimentions…..

WHAT IS TIME?

In physics, time is described as a  dimention much like length, width, and height.When you travel from your house to the grocery store, you are travelling through a direction in space, making headway in the spatial dimention -length width and height. But you are also travelling forward in time, the fourth dimention.(Sara Goudarzi)

What does a dimention mean?

A dimention is a degree of freedom of a system.  In simple words it is a numberof ways or direction in which change can take place in a system.   we can understand by the following example.
Imagine an ant walking on a thread. It can move forward and  backward only.It cannot move side ways That means its degree of freedom of movement is in one dimention only. Now imagine that ant is placed on a flat surface. It can move forward sideways but not upwards or downwards. That means its degree of freedom of movement is two dimention.  Now imagine an ant has wings . Its degree of freedom of movement is upwards downwards sideways forward and backwards.  Therefore its degree of freedom of movement is three dimention like us.

Bob Singer NASA Engineer says , an object that actually  exits from the time it came into existantance until it ceases to exist has a duration the fourth dimention.
That means the ant that was moving on the thread had not one but two dimention one was space and the other time. In the same way we live in this world in three dimentions plus one time dimention.
Special relativity propounded by Einstein demolished the concept
of absolute time. He unified time and space terming spacetime
He termed it as our fourth dimention. In space we can move forward and backwards but dimention of space time we can move in
one direction that is forward only. the concept of time dilation in special relativity t ells us that time slows down for an object as it speeds up to the speed of light. For example, a person A who is travelling in space with a speed of light, and a person B who is stationary B on Earth, the person A who returns to Earth say after five years in space sees that the person B  on Earth has aged in decades. The faster you move the slower time changes for you! It is a fact which has been verified through experiments.

Time is unique dimention you can move in one direction that is forward you cannot move backward.

Can we Time Travel?

Time Travel has been mans wildest fantasies for centuries..
H. G Wells “The Time Machine” and the latest fiction movie “INTERSTELLAR”

Intersteller is a science fiction the film is directed by Chritopher Nolan the film features a crew of astronauts who travel through a wormhole in search of a new home for humanity.

(Matthew McConaughey and Anne Hathaway star as Joseph “Coop” Cooper and Dr. Amelia Brand respectively.)

According to Einstein’s theory of general relativity, a wormhole could act like a bridge though space-time by connecting two distant points with a shortcut the Einstein Rosen bride in 1935.
In the late 1980s, Thorne said that a wormhole could be made into a time machine.

The  early Earth

¬The meaning of fugue (fyoog) is a musical composition in which a short melody is successfully repeated by different voices or instruments. “Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live . In a hundred billion galaxies, you will not find another.”…Carl Sagan, Cosmos.

Is Earth a single voice of one lonely theme “Music of Life” in the Universe or is there (a cosmic fugue )– different voices playing the Music of Life in billions of planets circling the Suns in the numerous ‘Galaxies’. In another words is there an extraterrestrial life? What kind of life there is? Does they constitute of the same organic matter as we on earth are made of. All living things¬¬¬¬¬¬¬¬¬¬ on earth have common organic chemistry and common evolutionary heritage.

carbon atom plays the central role in all complex or simple or microscopic beings.¬¬¬¬ Billions of years ago our earth was lonely and barren. There was no life. How the carbon based elements made? How did they come together to form a single cell… then multicellular organisms formed and complex beings as we came into existence?

4. Charles Darwin

Charles Darwin

Probably all the organic beings which have ever lived on this Earth have descended from some one primordial form into which life was first breathed—There is a grandeur in this view of life that, whilst this planet has gone cycling on according to the fixed laws of gravity from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved…..Charles Darwin…The Origin of Species 1859”

5. Structure of DNA

Structure of DNA

According to the Research carried by Scientists & paeleantalogists our Earth was formed some 4.5 billion years ago. The Hydrogen rich molecules of the primitive Earth were broken due to lightening and ultra violet radiations.They recombined into more complex molecules they were the earliest ancestors of “deoxyribose neuclic acid”DNA the master molecule of Life on Earth.

What is DNA? DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms It is located in the Nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. The DNA molecule resembles like a spiral strands called double helix.

The structure of the double helix is somewhat like a ladder, the rungs of this ladder is made of the four bases A(adenine)G(guanine)C(cytosine)T(Thymine) The sides of this ladder is made of sugar and phosphorus. Together a base sugar and phosphorus is termed nucleotide.

know from the fossil records that the origin of life happened soon after in ponds and oceans of the primitive Earth. The first organisms were unicellular (single cell) algae then by mutation they evolved to multi cellular .

Cambrian Explosion: Around 500 million years ago in the Cambrian era rocks the fossils of different animals were found at the floors of Cambrian oceans. It spoke about their existence. After the Cambrian Explosion new adaptations took place with speed. First fish and the first vertebrate appeared winged insects arose , amphibians creatures like lung fish who survived both on land and water .

The first trees and the first reptiles emerged. The dinosaurs evolved the first mammals appeared. The first flowers and birds appeared; the dinosaurs became extinct , the earliest cetaceans, ancestors to the dolphins and whales, arose and in the same period primates the ancestors of monkeys the apes and the humans arose.. (Carl Sagan)

Few million years ago the first true humans emerged. We have known and heard the voice of life on one small world only. Will we be able to hear the voice of life on other worlds? Although it may not be that easy but at least we have begun our search to listen for voices (extraterristial life) in cosmic fugue.

The Title of my blog One Voice in the Cosmic Fugue is taken from Carl Sagans book COSMOS.
