Radius Of 46 Billion Light Years.?

              Observable Universe...

      So our today's topic of discussion is a tiny part of our universe which is 'Observable Universe'.

          First of all, Let us discuss about definition of universe , which is "The physical universe is defined as all of space and time and their content."

   How does word Universe born?

Word universe is come with a long journey. So, lets jump into it..

In Latin language uni means one and vertere means turned. Then word vertere evolved into word versus. Now by combining words uni and versus the word universus formed. Then word universus evolved into word  universum. From old French univers and Latin universum the word Universe born in late middle English

          In today's world almost every information is available on wikipedia but everyone wouldn't get that wiki's typical language. So, we will try to explain everything in as simple as possible language.

           Let us suppose that our Universe is spherical, which is already. And sphere always has a diameter. So the diameter of our observable universe is currently estimated to be 93 billion light-years. In km 8.79847934 x 1023 kilometers. This is our Giant universe's Giant diameter.There are at least 2 trillion(2,000,000,000,000) galaxies in the observable universe like our Milky way.

         This is a little large important image to understand our worth among galaxies. Apart from dishonour,

 What is the Universe made of? 

   The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.

         We will discuss about them briefly on another day...

But now, let's talk about age of Universe. So, what is age of our Observable Universe? 

          As you can see in above image, age of our universe is around 13.77 billion years. It means that our Universe's age is 13,770,000,000. How amazing and shocking,isn't it...?
