The universe (Latin: universus) is
all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy
. … At the largest scale, galaxies are distributed uniformly and the same in all directions, meaning that the universe has neither an edge nor a center.
How do scientists believe the universe was created?
The Big Bang theory
says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn’t occur in an already existing space. Rather, it initiated the expansion—and cooling—of space itself.
What is the universe according to science?
The universe (Latin: universus) is
all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy
. … At the largest scale, galaxies are distributed uniformly and the same in all directions, meaning that the universe has neither an edge nor a center.
What shape do scientists think the universe is?
The observable universe can be thought of as
a sphere
that extends outwards from any observation point for 46.5 billion light-years, going farther back in time and more redshifted the more distant away one looks.
How will universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will
end with a Big Freeze
. … Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.
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.
Who created the God?
We ask, “If all things have a
creator
, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.
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
.
Is our universe open or closed?
This is known as an
open 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.
How many dimensions are there?
The world as we know it has
three dimensions of space
—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
How does universe look like?
The observable universe is thus a sphere with
a diameter of about 28.5 gigaparsecs
(93 billion light-years or 8.8×10
26
m). Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22×10

How long will universe last?
22 billion years
in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if Higgs boson field is metastable.
What happens when you reach the end of space?
It will expand forever;
the galaxies within groups and clusters will merge together to form a giant super-galaxy
; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes …
Does space ever end?
Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite,
with no end
. … Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Who is the first God of the world?
Brahma
is the first god in the Hindu triumvirate, or trimurti. The triumvirate consists of three gods who are responsible for the creation, upkeep and destruction of the world. The other two gods are Vishnu and Shiva.
How old is our universe?
Using data from the Planck space observatory, they found the universe to be
approximately 13.8 billion years old
.
