ASTROPHYSICS
	WHAT IS BIG BANG THEORY ?

THE BIG BANG THEORY IS PREVAILING COSMOLOGICAL MODEL AND THEORY FOR THE UNIVERSE FROM EARLIEST KNOWN PERIODS THROUGH ITS SUBSEQUENT LARGE SCALE EVOLUTION. THEORY THAT THE UNIVERSE AS WE KNOW IT BEGAN 13-14 BILLION YEARS AGO.LATEST ESTIMATE (13.82+_.05 BILLION YEARS). The INITIAL STATE WAS A HOT,DENSE AND UNIFORMLY SEA OF PARTICLES THAT FILLED SPACE AND WAS EXPANDED RAPIDLY.

	WHAT IT DESCRIBES :

	HOW THE EARLY UNIVERSE EXPANDED AND COOLED. 	HOW THE LIGHT CHEMICAL ELEMENTS FORMED. 	HOW THE MATTER CONGEALED TO FORM GALAXIES ,STARS AND PLANETS.

•	WHAT IT DOESN’T DESCRIBE:

	WHAT CAUSE THE EXPANSION OF THE UNIVERSE ?

“THE BIG BANG THEORY DESCRIBES ONLY THE AFTERMATH OF THE BANG “ -ALAN GUTH (MIT)...

	WHERE DID THE MATTER CAME FROM? 	WHY IT BANGED,WHAT BANGED ,WHAT CAUSED THE BANG ?

NOW TO REMOVE THESE PROBLEMS ABOUT BIG BANG COSMOLOGY. I THINK I CAN CHANGE THE CONCEPT OF BANG IN THE WORD BIG BANG.

	WHY THIS HYPOTHESIS NAMED AS OMEGA-POINT? WE KNOW IN GREEK ALPHABETS LAST ALPHABET IS OMEGA SO I HAVE USE THIS WORD WHICH MEANS THIS HYPOTHESIS HELPSTO UNDERSTAND ULTIMATE FATE OF THE UNIVERSE.

ACCORDING TO ME...

	BIG BANG IS JUST A SERIES OF EXPLOSIONS WHICH IS GOING ON EVERY TIME EVERYWHERE IN SPACE AND TIME WHICH MAY BE CALLED ETERNAL BANGS  ,WHICH FORMS NEW UNIVERSES.AS WE DON'T KNOW WHAT EXACTLY TIME IS ? IN THE PRESENT COSMOS,SO I CAN SAY WE ARE LIVING IN THAT UNIVERSE WHICH IS BEFORE  ONE OF THOSE BIG BANGS(WHICH WILL HAPPENS IN FUTURE).AND SIMPLY I CAN SAY WE ARE LIVING  IN  A MULTIVERSE  (INFINITE  NUMBER  OF PARALLEL  UNIVERSES).MAY  BE  LAWS OF PHYSICS ARE DIFFERENT  IN  DIFFERENT UNIVERSES  LIKE  DIFFERENT DIMENSIONS MAY BE MORE THAN 3(ACCORDING TO STRING  THEORY). BECAUSE BIG BANG THEORY HAS A LOT OF FLAWS IN UNDERSTANDING(VOILATING FIRST AND SECOND LAW OF THERMODYNAMICS AND EVEN RELATIVITY) I MEAN TO SAY UNIVERSE(SPACE  AND  TIME)HAD  NO BEGINING.IT EXISTED  FOREVER. NOW THE QUESTION ARISES WHAT HAPPENED BEFORE OUR PRESENT BIG BANG ? YOU MUST BE KNOWING THAT MATTER ITSELF  ORIGINATED  FROM THE  BIG BANG(FROM A SINGLE POINT).ACCORDING TO PARTICLE  PHYSICS,EVERY  MATTER  HAS  IT'S ANTIMATTER.THE  MATTER  RESPONSIBLE  FOR  OUR LIFE MAY NOT HAVE BEEN PRESENT IN THE UNIVERSE BEFORE  OUR BIG BANG AND WE KNOW THAT MATTER AND ANTIMATTER ANHILLATE  EACH OTHER WITH HUGE AMOUNT OF ENERGY PRODUCING SOME BY-PRODUCT. THIS HUGE  AMOUNT OF ENERGY MUST HAVE  SERVED AS A FUEL TO CREATE OUR PRESENT UNIVERSE(ACCORDING TO  MASS ENERGY EQUIVALENCE  PRINCIPLE).THESE  BY-PRODUCTS  MAY PROTONS ,ELECTRONS ETC. WHICH IS RESPONSIBLE  FOR OUR LIFE. THERE IS SOME OTHER REASON – AS WE KNOW SPACE IS EXPANDING WHEN SPACE IS EXPANDING THERE IS DISCHARGING OF VACUUM ENERGY(ENERGY OF EMPTY SPACE) AT COSMIC LEVEL WHICH IS ALSO GIVING US HUGE HUGE AMOUNT OF ENERGY AND WE CAN SAY IT THE BIG BANG CREATING NEW UNIVERSES. NOW THE ANOTHER QUESTION ARISES, HOW WILL THE NEXT BIG BANG OCCUR? IF THE UNIVERSE'S EXPANSION RATE DOES NOT EXCEED THE ESCAPE SPEED ,THEN THE MUTUAL

GRAVITY OF ALL IT'S MATTER WILL EVENTUALLY CAUSE IT TO  CONTRACT. (E.G : WHEN YOU THROUGH AN APPLE VERTICALLY UPWARDS DUE TO EFFECT OF ATTRACTIVE GRAVITY GIVEN BY THE EARTH APPLE SLOWS DOWN AND EXPANSION BETWEEN APPLE AND THE EARTH STARTS CONTRACTING.) IF ENTROPY CONTINUES TO INCREASE IN THE  CONTRACTION BETWEEN SOME OF THE MATTER (ACCORDING TO THERMODYNAMICS),EVENTUALLY ALL  MATTER WOULD COLLAPSE INTO BLACKHOLES,WHICH MAY BECOME UNIFIED BLACKHOLES .IF THE  DENSITY OF THE  UNIVERSE  IS LESS THAN IT'S CRITICAL DENSITY(HUBBLE'S  LAW),THEN  THE  GRAVITATIONAL FORCE  WILL  STOP  THE  EXPANSION OF UNIVERSE .ASSUMING THAT THERE  IS NO REPULSIVE  FORCE SUCH AS COSMOLOGICAL CONSTANT(DARK ENERGY). CONVERSELY IF THE  DENSITY OF THE  UNIVERSE  IS LESS THAN THE CRITICAL  DENSITY THE  UNIVERSE CONTINUES TO EXPAND AND GRAVITATIONAL  PULL WILL  NOT BE ENOUGH TO STOP THE UNIVERSE FROM EXPANDING .THIS  SCENARIO  WOULD RESULT IN BIG FREEZE  WHERE  THE UNIVERSE  COOLS AS IT EXPANDS.

AND THESE SERIES OF EXPLOSIONS TELLS US TIME IS NOTHING BUT INFINITE  CYCLIC PROCESS HAPPENING IN THESE UNIVERSE’S. AMIT KUMAR JHA JAMIA MILLIA  ISLAMIA Amit k jha (talk) 05:20, 6 May 2017 (UTC)
