WHY IS SPACE BLACK

WHY IS SPACE BLACK??

HELLO DEAR FRIENDS, IN THIS POST WE WILL BE 

DISCUSSING THAT "WHY SPACE APPEARS BLACK"??

AS WE KNOW OUR UNIVERSE CONSISTS OF MILLIONS  AND BILLIONS OF STARS LIKE OUR "SUN" WHICH PRODUCES AN ENORMOUS  AMOUNT OF HEAT AND LIGHT ENERGY, AND THUS  SPACE SHOULD BE BRIGHT, BUT, IT ISN'T SO...

SO LET'S BEGIN TO REVEAL THE MYSTERY,

HOW DO WE SEE?? 

WE ALL KNOW THAT WE CAN SEE THE OBJECTS WHEN SOME REFLECTED LIGHT (REFLECTED BY THE OBJECT) REACHES OUR EYES ... THIS ACTION IS SO FAST BECAUSE OF THE SPEED OF LIGHT  WHICH IS: 29,97,92,458 m/s

HOW BIG IS SPACE?

OUR SPACE IS SO LARGE AND ENORMOUS THAT  WE CAN'T  IMAGINE THE BORDERS OF THE UNIVERSE...

THIS IS BECAUSE OUR UNIVERSE IS CONTINUOUSLY  EXPANDING...

OUR OBSERVABLE UNIVERSE IS ABOUT 46.6 BILLION  LIGHT YEARS IN RADIUS.

AND,

ACCORDING TO A PHYSICIST J.RICHARD GOTT AND HIS COLLEAGUES, WE GET AN OBSERVABLE UNIVERSE OF ABOUT 45.66 BILLION LIGHT-YEARS IN RADIUS.

THE LIGHT FROM DISTANT STARS COULD NOT REACH US AS LIGHT HAVE A SPECIFIC SPEED LIMIT OF ABOUT 3 CRORE METERS PER SECOND.

HOW WE SEE SPACE?

WE SEE THE SPACE BY THE PHENOMENA OF REFLECTION OF LIGHT.

WHEN OUR EYES RECEIVES THE LIGHT REFLECTED FROM NUMEROUS AND VARYING OBJECTS IN SPACE,

AN IMAGE OF THEM IS CREATED, THUS ENABLING US TO SEE SOME OBJECTS IN THIS VAST UNIVERSE.

AS WE ALREADY KNOW THAT THIS UNIVERSE IS CONTINUOUSLY EXPANDING, THE VISIBLE LIGHT FROM VARIOUS CELESTIAL BODIES LIKE GIGANTIC STARS, SUPERNOVAS AND OTHER OBJECTS, GETS STRETCHED OUT AND EVENTUALLY WHEN IT REACHES TO OUR EYES OUR EYES COULD'NT DETECT ANY VISIBLE LIGHT THUS MAKING THE SPACE BLACK...

I HOPE YOU HAVE NOW UNDERSTOOD WHY THE SPACE IS BLACK…EVEN IT HAS BILLIONS AND BILLIONS OF STARS AND AN ENORMOUS AMOUNT OF LIGHT.
