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
. In addition to explaining current cosmological theory, the authors speculate on what kinds of life might exist in future eras of the universe.
What happens after the dark era?
Dark Era and Photon Age
After
all the black holes have evaporated
(and after all the ordinary matter made of protons has disintegrated, if protons are unstable), the universe will be nearly empty. Photons, neutrinos, electrons, and positrons will fly from place to place, hardly ever encountering each other.
What era is our universe in?
We are already in
the Universe’s 6th and final era
. The Universe is not the same today as it was yesterday. With each moment that goes by, a number of subtle but important changes occur, even if many of them are imperceptible on measurable, human timescales.
What is the age of black hole?
This
13-Billion-Year-Old
Supermassive Black Hole Is the Oldest Ever Found | Smart News | Smithsonian Magazine.
Are we in the second era?
Right now, we’re in the second era
. We’re in the middle, or thereabouts, of the universe’s Stelliferous era.
What is the dark era?
The period following the demise of black holes
is known as the Dark Era, which is expected to begin sometime around 10101 years after the Big Bang, though its start depends on how long black holes last. So when — and if — this era ends is anybody’s guess. Our understanding of the cosmos is far from complete.
What is the first era of universe?
The
Primordial Era
is defined as “−50 < n < 5”. In this era, the Big Bang, the subsequent inflation, and Big Bang nucleosynthesis are thought to have taken place. Toward the end of this age, the recombination of electrons with nuclei made the universe transparent for the first time.
What will happen in 100 trillion years?
And so, in about 100 trillion years from now, every star in the Universe, large and small, will be
a black dwarf
. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs. … The Universe will be completely dark.
Will the universe last forever?
This suggests that the universe began – very small and very dense – about 13.82 billion years ago, and it has expanded and (on average) become less dense ever since. … There is a strong consensus among cosmologists that
the shape of the universe is considered “flat” and will continue to expand forever
.
Will a black hole come to earth?
Absolutely not
. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. … It would get very dark of course and very cold, but the black hole’s gravity at our distance from it would not be a concern. Is there life on other planets?
What is inside a Blackhole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don’t produce light, a black hole is not empty, It’s actually
a lot of matter condensed into a single point
. This point is known as a singularity.
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.
Do we live in black holes?
We can’t calculate what happens in a black hole’s singularity — the laws of physics literally break down — but we can calculate what happens on the boundary of an event horizon. …
We might live in a universe within a black hole within a universe within a black hole
. It might just be black holes all the way down.
How long is a era?
An era in geology is a time of
several hundred million years
. It describes a long series of rock strata which geologists decide should be given a name. An example is the Mesozoic era, when dinosaurs lived on the Earth. An era is made up of periods, and several eras make up an eon.
How long is an era in history?
One of the ways history is commonly divided is into three separate eras or periods: the Ancient Period (3600 BC – 500 AD), the Middle Ages (500 -1500), and the Modern Era (1500-present). According to this classification, the eras last
hundreds of years
, even thousands of years in the case of the Ancient Period.
What race are the Akaviri?
It is the homeland of four seemingly unrelated races collectively referred to as the “Akaviri.” These races are composed of the
Demons of Kamal, the serpent-men of Tsaesci, the Monkey People of Tang Mo, and the Tiger Dragons of Ka’Po’Tun
.
