The sphere of space that will become the observable universe is approximately 10 light-years in radius at this time. Lepton epoch: 1 s ~ 10 s: 10 10 K ~ 10 9 K (1 MeV ~ 100 keV) Leptons and antileptons remain in thermal equilibrium—energy of photons is still high enough to produce electron-positron pairs. Big Bang nucleosynthesis: 10 s ~ 10 3 ...
The concept was popularized by Carl Sagan in his 1977 book The Dragons of Eden and on his 1980 television series Cosmos. [2] Sagan goes on to extend the comparison in terms of surface area, explaining that if the Cosmic Calendar were scaled to the size of a football field, then "all of human history would occupy an area the size of [his] hand".
Timeline from Big Bang to the near cosmological future – Visual representation of the universe's past, present, and future Tiny Graphical timeline from Big Bang to Heat Death – Future scenario if the expansion of the universe will continue forever or not - Timeline uses the log scale for comparison with the double-logarithmic scale in this ...
The timeline of the Universe lists events from its creation to its ultimate final state. For a timeline of the universe from formation to the present day, see: Timeline of cosmological epochs; For a timeline of the universe from the present to its presumed conclusion, see: Timeline of the far future
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 .
c. 16th century BCE – Mesopotamian cosmology has a flat, circular Earth enclosed in a cosmic ocean. [1]c. 15th–11th century BCE – The Rigveda of Hinduism has some cosmological hymns, particularly in the late book 10, notably the Nasadiya Sukta which describes the origin of the universe, originating from the monistic Hiranyagarbha or "Golden Egg".
Timeline of world history. These timelines of world history detail recorded events since the creation of writing roughly 5000 years ago to the present day. For events from c. 3200 BC – c. 500 see: Timeline of ancient history; For events from c. 500 – c. 1499, see: Timeline of post-classical history
This timeline of the Big Bang shows a sequence of events as currently theorized. It is a logarithmic scale that shows 10 ⋅ log 10 {\displaystyle 10\cdot \log _{10}} second instead of second . For example, one microsecond is 10 ⋅ log 10 0.000001 = 10 ⋅ ( − 6 ) = − 60 {\displaystyle 10\cdot \log _{10}0.000001=10\cdot (-6)=-60} .
