In this Cosmology section of Physics we cover the topics listed in the table below, each topic has a written tutorial (which you can read on your screen, print to read or use a web reader), a video tutorial, revision notes, revision questions and supporting calculators which allow you to check your own computations and calculations.
|22.1||Earth and Other Celestial Bodies|
|22.2||Sun and Planetary Motion|
|22.3||The Moon's Movement. Eclipses. Calendars|
|22.5||Evolution of Stars|
|22.6||Galaxies and Hierarchic Structures in the Universe|
|22.7||Astronomical Measurements and Observations|
|22.8||Orientation in the Sky and Constellations|
|22.9||Expansion of the Universe|
|22.10||Big Bang Model and Temperature|
|22.11||Chronology of the Universe|
|22.12||Formation of Galaxies and Solar System. Actual Problems|
This section includes information from (1) astrophysics and (2) cosmology. In astronomy, planets, natural satellites, comets, asteroids, stars, solar system, orbits, etc., are some of the concepts discussed in the first tutorials, while eclipses, calendars, horizon, sun layers, solar system, etc., are explained in the following part. Then, we continue with cosmology, where concepts like the evolution of stars, galaxies, groups of galaxies, constellations, Universe (including its origin, i.e. the Big Bang) are explained, we conclude with chronology and a discussion of the possible fate of the Universe, as well as covering some of the challenges scientists face today in providing a satisfactory explanation of the origins of the Universe and its continuity.
In addition to the Cosmology tutorials, we also provide online Cosmology Calculators which allow you to calculate specific Cosmology formula in support of the tutorials or to check and verify your own calculations in support of your homework, coursework or thesis.
The following Physics Calculators are provided in support of the Cosmology tutorials.
