Observable Universe - Diameter 93 billion light years

Almighty Allah created the universe from a single point with a huge explosion. While all other explosions damage the existing order, the 300 billion galaxies in the universe emerged from zero volume, nothing in other words, with this explosion, known as the Big Bang. The Galaxy (Milky Way) we live in is just one of these 300 billion galaxies. There are 250 billion stars in the Milky Way. The sun is one of these 250 billion stars.
                                      
Allah has created the Earth as a living space within the boundless universe. We live on a world that occupies almost no place at all within infinity. In fact, not just our Earth but even our galaxy occupies a tiny place in the universe.




This is the picture of stars in the space. It is seen that these stars are very crowded and congested in space. Our this belief is not real and true. Now looking at the reality, the average distance of stars are 5 light years.

How much distance this 5 light years occupies?

The speed of light is 3,00,000 km in a second.

Light travels 48 trillion km in 5 years.

What is 48 trillion?

48 trillion = 48 thousand billion*.

This is the distance only between two stars.

(*In the American system one billion is 1,000,000,000 and a trillion is 1,000,000,000,000 so one trillion is one thousand times one billion.)

There are 250 billions stars in our galaxy. One can not imagine  the diameter of galaxy if it is occupies 250 billion stars. How many galaxies are there in our universe? There  are 300 billions galaxies in observable universe.
How much distance is between two galaxies?




Our galaxy is Milky Way galaxy, it has a neighbor galaxy named Andromeda galaxy. Andromeda galaxy is 2.2 million light years away from us.

The farthest galaxy seen is about 13 billion light years away.

How big is the universe in light years?

It is estimated that the diameter of the observable universe is about 28.5 gigaparsecs (93 billion light-years, 8.8×1023 kilometres or 5.5×1023 miles), putting the edge of the observable universe at about 46.5 billion light-years away. This is only  estimation of observable  universe.

Can anybody imagine the diameter of 93 billion light years?

Allah has created this universe with a  
Single command "Be!" and it is.
This is the power of Almighty Allah.
