Oct 20, 2022 · 380,000 years to 1 billion years after the Big Bang: During this enormously long Era of Atoms, matter grew into the remarkable variety we now know. The stable atoms of hydrogen and helium slowly drifted together in patches, due to gravity. This further emptied space.
From our current understanding of how the Big Bang might have progressed, taking into account theories about inflation, Grand Unification, etc, we can put together an approximate timeline as follows: Planck Epoch (or Planck Era), from zero to approximately 10-43 seconds (1 Planck Time): This is the closest that current physics can get to the ...
- How it all started. The Big Bang was not an explosion in space, as the theory's name might suggest. Instead, it was the appearance of space everywhere in the universe, researchers have said.
- The universe's first growth spurt. When the universe was very young — something like a hundredth of a billionth of a trillionth of a trillionth of a second (whew!)
- Too hot to shine. Light chemical elements were created within the first three minutes of the universe's formation. As the universe expanded, temperatures cooled and protons and neutrons collided to make deuterium, which is an isotope of hydrogen.
- Let there be light. About 380,000 years after the Big Bang, matter cooled enough for electrons to combine with nuclei to form neutral atoms. This phase is known as "recombination," and the absorption of free electrons caused the universe to become transparent.
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
Apr 30, 2018 · Created by Slovak graphic designer Martin Vargic, the Timeline of the Universe covers the past 13.8 billion years of space, and then plots out what's likely to occur in the next 10 billion or so. He's even separated everything out into things that affect space, Earth, life, and humanity, just so you can really easily see what's going to hit us ...
May 1, 2024 · Key Takeaways. Our Universe arose in the aftermath of cosmic inflation, triggering the hot Big Bang some 13.8 billion years ago that eventually gave rise to us. The Universe passed through many ...

What is the earliest meaningful time after the Big Bang?
The timeline of the early universe outlines the formation and subsequent evolution of the Universe from the Big Bang (13.799 ± 0.021 billion years ago) [ 1 ] to the present day. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age.
