This timeline of cosmological theories and discoveries is a chronological record of the development of humanity's understanding of the cosmos over the last two-plus millennia. The Sun, the Moon, the planets, and the fixed stars have spheres. Some researchers studying models of the universe speculate that the universe's diameter could be 7 billion light-years across. Interestingly whilst most classical models were variations on geocentric models, one of the Pythagoreans, Aristarchus of Samos (c. 310 - 230 BC) proposed a model that placed the Sun at the centre, that is a heliocentric Universe. His model would be familiar to us today as a reasonable description of the solar system. A timeline of the universe shows the absolute beginning and the probable end. The universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. cosmological models, including Einstein's own model of a static universe. ), a Greek astronomer and mathematician, was the first to propose a model of the universe based on geometry. The Sun, the Moon, the planets, and the fixed stars have spheres. Figure 2.

There are a few published (though shared) timelines in the Wing Commander universe (most of these are taken directly from the manuals, and included to incorporate manual material into the database, and are the sources for the main shared timeline). We illustrate a brief and simplified picture of theorized stages in the evolution of the universe, to provide a context for discussing ΛCDM parameters. How ground-breaking scientists with bold theories and more innovative instruments took us from Ptolemy's geocentric view of the universe to our current powerful inflation model.

The best-supported theory of our universe's origin centers on an event known as the big bang. A fifth element, called aether, did not interact with the other four, but instead formed the heavenly bodies. One model comes from the mind of Nobel laureate Hannes Alfvà ©n, a Swedish plasma physicist. TIMELINE OF BIG BANG-INFLATION AND BARYOGENESIS. The far left depicts the earliest moment we can now probe, when a period of "inflation" produced a burst of exponential growth in the universe.

Leucippus of Abdera, the philosopher, is said to have conceived of the atomic universe. Brahe's model of the universe was a combination of both the models, with the earth being at the centre and the planet revolving around the sun, while it revolved around the earth. But the processes by which planets, stars, galaxies, and the universe form and change over time are also types of "evolution."

A succinct timeline of the historical developments in the science of cosmology, from the 16th Century to today. This graphic shows a timeline of the universe based on the Big Bang theory and inflation models. With machine learning, astrophysicists can now simulate vast, complex universes in a fraction of the time it takes with conventional methods. Others think it could be infinite. The Aristotelian model of basic elements. Plasma Universe Theory. The term "evolution" usually refers to the biological evolution of living things. Lemaître in 1927 (and, independently, Alexander Friedmann in 1922) discovered a family of solutions to Einstein's field equations of relativity that described not a static but an expanding universe. The ancient megalithic site, Stonehenge, in England near the midwinter solstice.
