How long will the Stelliferous era last?
The next era, which we’re currently in, is known as the Stelliferous Era, in which matter is organized into stars, planets, nebulae, and larger constructs, such as galaxies and galaxy clusters. This era is hypothesized to run from about 106 to 1014 (1 million to 100 trillion) years after the Big Bang.
What era is our universe in?

What is the primordial era?
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.
When did the Planck epoch start?
Planck epoch c. 0 seconds (13.799 ± 0.021 Gya): Planck epoch begins: earliest meaningful time. The Big Bang occurs in which ordinary space and time develop out of a primeval state (possibly a virtual particle or false vacuum) described by a quantum theory of gravity or “Theory of Everything”.
How long until universe ends?
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 the Higgs field is metastable.
How long until the last black hole evaporates?
It would take 10100 years, or a googol, for a supermassive black hole to fully disappear. “The entire age of the universe [is] a fraction of [the time] it would take,” says Priyamvada Natarajan, a researcher at Yale University who probes the nature of black holes.
What are the 5 eras of the universe?
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.
When was the dark era of the universe?
Beginning about 400,000 years after the Big Bang and lasting hundreds of millions of years, this so-called dark age of the universe marked the last time when empty space really was empty; no planets, no suns, no galaxies, no life — just a fog of hydrogen atoms forged by the Big Bang and left to slosh through the …
What ended the Planck Era?
The Electroweak Era ended when the Universe cooled sufficiently that W and Z bosons were no longer being created; they decayed away and without them the electroweak force separated from the electromagnetic one and became the short-range weak nuclear force.
Is there a Planck second?
Planck time is roughly 10−44 seconds. However, to date, the smallest time interval that was measured was 10−21 seconds, a “zeptosecond.” One Planck time is the time it would take a photon travelling at the speed of light to cross a distance equal to one Planck length.
What will happen in 100 trillion years?
By 1014 (100 trillion) years from now, star formation will end, leaving all stellar objects in the form of degenerate remnants. If protons do not decay, stellar-mass objects will disappear more slowly, making this era last longer.
