How Is The Universe Expanding ?

Hi Guys, today I am going to tell you about :-

HOW IS THE UNIVERSE EXPANDING ?


You all might know about the big bang theory, if you don't know about the big bang theory then click the link below :-


So you all might know that our universe is expanding very fast, greater than the speed of light.

 

According to Einstein no object can travel faster than the speed of  light, So does the expansion of the universe violates einstein's theory ??



Not really, the object on the universe can't travel faster than light but the universe itself can expand faster than light.

The expansion of the universe should have stopped in some years after the big bang, but the expansion has not yet stopped. Why??

Why is the universe still expanding ??
 
The universe is still expanding due to a mysterious force called the dark energy, scientist yet don't know anything about the dark energy.



    The reason why we don't know much about this energy is  because the energy does not interacts with it's surroundings. Therefore, it is very hard to find out about dark energy.

Hello friends, today I am going to post my first topic about :- "HOW  WAS THE UNIVERSE  FORMED OR THE BIG BANG THEORY"  The big bang theory Some of the sub-topics that I will introduce to you are :- 1) About The Word 'THEORY' - From where did the word 'THEORY' came from?            - Meaning of Theory.  2) About the big bang theory - Who proposed the big bang theory and when was it proposed? - What is the big bang theory? 3) Is the universe expanding?  - Will big bang happen again? If yes, then how? ABOUT THE WORD 'THEORY' The word ' Theory ' was derived (came) from a Greek word .  Theory means  a supposition or a system of ideas intended to explain something. In simple words it means that a idea which is used to explain something, it is only a expectations or suggestions of scientist, for example from where did the earth got water but we don't know really because we

Hello  friends,  today I am going to post about :- BLACK HOLE Black hole Some of the sub-topics are :- 1) What Is A Black Hole      - How is a black hole formed?    - About black hole 2) Where Is Our Nearest Black Hole? 3) What Is Light Years? What Is A Black Hole Black hole is formed when the fuel (hydrogen) gets over in the cores of the stars, as there is no fuel, to oppose the force of gravity it starts to shrink and forms  a black hole or a neutron star . It has a very strong gravitational force, even light also can't escape from the gravitational force of the black hole. I have told you about this in my post called 'Nuclear fusion in stars' or you may see this video to know more about how a black hole is formed . Where Is Our Nearest Black Hole? The  closest black hole  we know is V616 Monocerotis , also known as V616 Mon . It's located about 3,000 light years away, and has between 9-13 times the mass of the Sun .
