The book divides the timeline of the universe into
five eras
: the primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era.

How many stages are in the Universe?
In the scientific sense, the universe is a self-sufficient system, and is determined by the cosmic scientific law. So, the universe can be divided into
eight stages
, just like an abrupt episode during the Earth’s evolution.
What are the 3 types of universe?
There are basically three possible shapes to the Universe; a
flat Universe (Euclidean or zero curvature)
, a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature).
What are the three major stages for the development of the Universe?
The creation of the Universe has passed through different stages. These stages may be divided into 3 eras depending on the energy/matter interaction processes. The first stage is the pre-compression era, the second is the compression era, and
the third is the post compression era
.
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.
Will the 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.
What was the first thing in the universe?
The Big Bang
is thought to have kick-started the universe about 13.7 billion years ago. At first, the universe was too hot and dense for particles to be stable, but then the first quarks formed, which then grouped together to make protons and neutrons, and eventually the first atoms were created.
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
.
Do we live in an open or closed universe?
With some rather large uncertainties, all methods point to
the universe being open
(i.e. the density parameter is less than one). But we need to remember that it is unlikely that we have detected all of the matter in the universe yet.
What is studied to see if the universe is open or closed?
NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) measured background
fluctuations in an effort to determine whether the universe is open or closed.
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.
What are the two main stages of the universe evolution?
And the nature of the universe is such that it underwent several stages of evolution, if you will, over its lifetime. These major stages –
the radiation era, recombination epoch, and reionization
– will be covered right now.
What is the early universe like?
In the first moments after the Big Bang,
the universe was extremely hot and dense
. … These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang.
Does time have an end?
According to Einstein’s General Relativity, which is our best current description of space and time, the only place where time – and also space –
ends is in a so-called singularity
. This involves gravitational forces becoming so intense that space and time lose all meaning.
Will the Galaxy end?
That’s accounting for the increase in star formation when the Milky Way and the Andromeda Galaxy collide around that time. … Thus, some 19 billion years after the Big Bang, the Milky Way will begin its slow but inexorable decline — and,
a trillion years from now, the end will come as its last star fades from visibility
.
