GOING VIRAL 👍DARK ENERGY AND DARK MATTER

DARK ENERGY AND DARK MATTER

The universe is so huge that is even bigger than our thoughts.

Many scientists are working really harder to make unknown things known to humans.
New things are discovered daily around the world by researchers.

As a matter of fact that we are in the age new era where tehnology dominates most.
 Evn to know more there were researches going on to discover more.
  Popular fields among research is about universe.Image result for dark energy and dark matter
 Scientists has found  a new things known as DARK MATTER AND DARK ENERGY IN SPACE.

 Baryonic matter made of protons and neutrons but dark matter is just a hypothetical one which gives solution for complex astronomical observations and problems.

 Scientists thought this dark matter is responsible for structure and formation of galaxies and also cosmic microwave background.

  Before the hypothesis came to be known everyone thought that space around the stars and planets are just empty and no matter is present in between.

 Dark energy and dark matter cannot be observed by our human experiments by gives many solutions to problems of universe if assumed some sort of matter and energy present in universe,Image result for dark energy and dark matter
  The space is expanding and scientists have given the name dark energy to the expansion generating force or substance of the universe.

 Dark energy which is the reverse of gravity which involves in pushing things away than pulling towards it.

 No theory has ever explained about this phenomena.
The astronomers in 1998 found that supernovae found to be dimmer and less brighter than expected to be.

  The US GOVERNMENT JDEM(JOINT DARK ENERGY MISSION) EXAMINED ABOUT THE TYPE LA SUPERNOVAE,DYING WHITE DWARFS DUE TO THEIR HIGH CONSISTENT LUMINOSITY WHICH ENDED IN 2010 WHICH WILL REPLACE  WFIRST(WIDE-FIELD INFRARED SURVEY TELESCOPE).

 In 1929,the expanding universe was discovered by Edwin Hubble which got attention after a decade which actually overtook all existing ides about universe that universe would contract and get collapsed termed big crunch.


Dark matter does not interact with any sort of radiation whereas ordinary baryons does.
This expanding behaviour generally observed by means of red shift and blue shift of light..
 The super clusters expand slower than what anticipated by cosmologic studies


 due to gravity around them

Several theories such as 

1.Dark energy
2.conformal gravity
3.entropic gravity.
4.dark electromagnetism.
5.unparticle physics 
have been proposed which still couldnot give exact behaviour of our universe.


 This dark matter and energy combinely constitute around 95.1% in total with density around   which is very low.
