New Space Documentary 2017.
The
Universe is all of time and space and its contents. It includes
planets, moons, minor planets, stars, galaxies, the contents of
intergalactic space, and all matter and energy. The size of the entire
Universe is unknown.The earliest scientific models of the Universe were
developed by ancient Greek and Indian philosophers and were geocentric,
placing Earth at the center of the Universe.Over the centuries, more
precise astronomical observations led Nicolaus Copernicus (1473–1543) to
develop the heliocentric model with the Sun at the center of the Solar
System. In developing the law of universal gravitation, Sir Isaac Newton
(NS: 1643–1727) built upon Copernicus's work as well as observations by
Tycho Brahe (1546–1601) and Johannes Kepler's (1571–1630) laws of
planetary motion.Further observational improvements led to the
realization that our Solar System is located in the Milky Way galaxy,
which is one of many galaxies in the Universe. It is assumed that
galaxies are distributed uniformly and the same in all directions,
meaning that the Universe has neither an edge nor a center. Discoveries
in the early 20th century have suggested that the Universe had a
beginning and that it is expanding at an increasing rate.The majority of
mass in the Universe appears to exist in an unknown form called dark
matter.The Big Bang theory is the prevailing cosmological description of
the development of the Universe. Under this theory, space and time
emerged together 13.799±0.021 billion years ago with a fixed amount of
energy and matter that has become less dense as the Universe has
expanded. After the initial expansion, the Universe cooled, allowing the
first subatomic particles to form and then simple atoms. Giant clouds
later merged through gravity to form galaxies, stars, and everything
else seen today.There are many competing hypotheses about the ultimate
fate of the Universe and about what, if anything, preceded the Big Bang,
while other physicists and philosophers refuse to speculate, doubting
that information about prior states will ever be accessible. Some
physicists have suggested various multiverse hypotheses, in which the
Universe might be one among many universes that likewise exist.The
Universe can be defined as everything that exists, everything that has
existed, and everything that will exist.According to our current
understanding, the Universe consists of spacetime, forms of energy
(including electromagnetic radiation and matter), and the physical laws
that relate them. The Universe encompasses all of life, all of history,
and some philosophers and scientists suggest that it even encompasses
ideas such as mathematics and logic. The word universe derives from the
Old French word univers, which in turn derives from the Latin word
universum.The Latin word was used by Cicero and later Latin authors in
many of the same senses as the modern English word is used.A term for
"universe" among the ancient Greek philosophers from Pythagoras onwards
was τὸ πᾶν tò pân ("the all"), defined as all matter and all space, and
τὸ ὅλον tò hólon ("all things"), which did not necessarily include the
void.Another synonym was ὁ κόσμος ho kósmos (meaning the world, the
cosmos).Synonyms are also found in Latin authors (totum, mundus, natura)
and survive in modern languages, e.g., the German words Das All,
Weltall, and Natur for Universe. The same synonyms are found in English,
such as everything (as in the theory of everything), the cosmos (as in
cosmology), the world (as in the many-worlds interpretation), and nature
(as in natural laws or natural philosophy).
