The observable universe is everything that we can detect. It is a
sphere 93 billion light-years in diameter
, centered on Earth.
What is the size of a universe?
The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (
93 billion light-years
, or 8.8×10
26
metres or 2.89×10
27
feet), which equals 880 yottametres.
What is the structure of the universe?
[/caption]The large-scale structure of the Universe is made up
of voids and filaments
, that can be broken down into superclusters, clusters, galaxy groups, and subsequently into galaxies.
What is the biggest structure in the universe?
| Structure name (year discovered) Maximum dimension (in light-years) | Ursa Major Supercluster 200,000,000 | Komberg-Kravtsov-Lukash LQG 10 180,000,000 | Ophiuchus Supercluster 170,000,000 | Virgo Supercluster 110,000,000 |

What is the origin and structure of the universe?
The cosmology or structure of the universe consisted of
the Milky Way galaxy with the sun at the center of the galaxy
. … From Aristotle (384-322 B.C.) came the idea of a static universe, although his was geocentric or earth- centered with circular orbits for the moon, sun, planets, and stars.
What is shape of universe?
The shape of the universe depends on its density. If the density is more than the critical density, the universe is closed and curves like
a sphere
; if less, it will curve like a saddle.
What star do we live in?
All the stars we see in the night sky are in
our own Milky Way Galaxy
. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
Does the universe 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 universe?
Many religious persons, including many scientists, hold that
God
created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
Which is bigger galaxy or universe?
Galaxies come in many sizes.
The Milky Way is big
, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! … Our Sun is one star among the billions in the Milky Way Galaxy.
What is the fastest thing in the universe?
Laser beams travel at the speed of light
, more than 670 million miles per hour, making them the fastest thing in the universe.
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
.
Does space have a structure?
During the twentieth century, scientists learned that space is not “nothingness.” First, Einstein showed that space has structure:
It is flexible and can be stretched
. … In fact, there is now evidence that space itself MAY possess some slight amount of energy of its own, of a form previously unknown.
What are the origin of the universe?
Origins of the universe, explained. … The best-supported theory of our universe’s origin centers on
an event known as the big bang
. This theory was born of the observation that other galaxies are moving away from our own at great speed in all directions, as if they had all been propelled by an ancient explosive force.
How old is the universe?
The universe is
(nearly) 14 billion years old
, astronomers confirm. With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).
