    1936 Eugene Wigner develops the theory of neutron absorption by atomic nuclei; 1936 Hermann Arthur Jahn and Edward Teller present their systematic study of the symmetry types for which the Jahn–Teller effect is expected [8] 1937 Carl Anderson proves experimentally the existence of the pion predicted by Yukawa's theory.

  3. Chronology of the universe - Wikipedia

    en.wikipedia.org/wiki/Chronology_of_the_universe

    In inflationary models of cosmology, times before the end of inflation (roughly 10 −32 seconds after the Big Bang) do not follow the same timeline as in traditional Big Bang cosmology. Models that aim to describe the universe and physics during the Planck epoch are generally speculative and fall under the umbrella of "New Physics".

  4. Cosmic Calendar - Wikipedia

    en.wikipedia.org/wiki/Cosmic_Calendar

    The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.

  5. History of atomic theory - Wikipedia

    en.wikipedia.org/wiki/History_of_atomic_theory

    The current theoretical model of the atom involves a dense nucleus surrounded by a probabilistic "cloud" of electrons. Atomic theory is the scientific theory that matter is composed of particles called atoms. The definition of the word "atom" has changed over the years in response to scientific discoveries.

  6. The Five Ages of the Universe - Wikipedia

    en.wikipedia.org/wiki/The_Five_Ages_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. In addition to explaining current cosmological theory, the authors speculate on what kinds of life might exist in future eras of the universe.

  7. Graphical timeline of the Big Bang - Wikipedia

    en.wikipedia.org/wiki/Graphical_timeline_of_the...

    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} .

  8. Universe - Wikipedia

    en.wikipedia.org/wiki/Universe

    The universe is all of space and time [a] and their contents. [10] It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of matter and energy, and the structures they form, from sub-atomic particles to entire galactic filaments.
