4054 - COSMIC MICROWAVE BACKGROUND ?

 

-    4054  -   COSMIC  MICROWAVE  BACKGROUND  ?      The sixth wonder of the Universe is the Cosmic Background Radiation.  It is everywhere, filling the entire Universe, in all places and in all directions.  You can see it as snow on your UHF TV by tuning the receiver between stations.


-----------------   4054   -    COSMIC  MICROWAVE  BACKGROUND  ?

-    What is so amazing is that you are seeing the oldest and most distant thing possible. The radiation was created 380,000 years after the Big Bang.  In the early moments after the Big Bang the matter was ionized to the extent not to allow radiation to escape. Light was trapped inside the expanding and cooling universe.

-

-     After 380,000 years things cooled down enough that atoms could begin to form neutralizing the mass of material and allowing light to escape filling the expanding universe with radiation.  Over the last 13,700,000,000 years this radiation has red-shifted to the lower microwave frequency range.  This is the Cosmic Background Radiation that we are detecting.  It is 2.9 degrees Kelvin and 2,400,000,000 hertz, cycles per second in the UHF frequency range.

-

-    When the background radiation is analyzed we find the effect of sound waves and the reverberations that occurred in the early Universe.  These shock waves have the effect of creating hot and cold regions in the radiations, slight shifts in frequency as higher frequency and lower frequency patches.

-

-    By studying these sound waves astronomers can estimate the original mass of the Universe.  Their astonishing conclusions are that:

-

-----------------------------  75% of the Universe is Dark Energy

-

-----------------------------   21% of the Universe is Dark Matter

-

-----------------------------   3.6% of the Universe is ordinary matter that we know.

-

-----------------------------   0.4% of the Universe is ordinary matter that we can see in visible light.

-

-   That leaves a whole lot of Universe that is unknown and yet to be discovered.  Studying the microwave background radiation allows us to see the edge of the Universe, the earliest moment of existence, the creation of mass and energy, the creation of space and time.  The sixth wonder of the Universe.
