. 9. … The diameter of the Observable Universe is about 100 billion years. It's unbelievably enormous as it seems, Observable Universe is a tiny slice of the Entire Universe.
How small our universe is?
Today, 13.8 billion years after the Big Bang, the Universe is

— in all directions — from our vantage point.
How small we are in the universe zoom out?
If you zoom from the biggest object, The Observable Universe
How small are we compared to the Milky Way?
Answer: Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^(17) km, and a diameter for the Earth of about 12756 km, the ratio of the diameter of the Milky Way galaxy to that of the Earth is
about 3.6×10^(13)
.
What is the biggest thing in the universe?
The largest known ‘object' in the Universe is
the Hercules-Corona Borealis Great Wall
. This is a ‘galactic filament', a vast cluster of galaxies bound together by gravity, and it's estimated to be about 10 billion light-years across!
What is outside the universe?
To answer the question of what's outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then
there can't be anything outside the universe
.
How old is our galaxy?
Astronomers believe that our own Milky Way galaxy is
approximately 13.6 billion years old
. The newest galaxy we know of formed only about 500 million years ago.
What galaxy do we live in?
We live in one of the arms of a large spiral galaxy called
the Milky Way
. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre. 100 000 years to cross from one side to the other.
Which arm of the Milky Way do we see?
When we look to the edge, we see a spiral arm of the Milky Way known as
the Orion-Cygnus Arm
(or the Orion spur): a river of light across the sky that gave rise to so many ancient myths. The solar system is just on the inner edge of this spiral arm.
What is the smallest thing in the universe?
Quarks
are among the smallest particles in the universe, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they can't be observed outside of their respective hadrons.
Is the Great Attractor God?

Does the universe have an end?
The end result is unknown
; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
How many universes are there?
There are still some scientists who would say, hogwash. The only meaningful answer to the question of how many universes there are is
one, only one universe
.
Who created the universe?
Many religious persons, including many scientists, hold that
