The Universe is all of time and space and its contents. [8] [9] [10] [11] The Universe includes planets , stars , galaxies , the contents of intergalactic space , the smallest subatomic particles , and all matter and energy . The observable universe is about 28 billion parsecs (91 billion light-years) in diameter at the present time . [2] The size of the whole Universe is not known and may be infinite. [12] Observations and the development of physical theories have led to inferences about the composition and evolution of the Universe. |

The Universe is commonly defined as the totality of everything that exists , [1] including all matter and energy , the planets , stars , galaxies , and the contents of intergalactic space . [2] [3] Definitions and usage vary and similar terms include the cosmos , the world and nature . Scientific observation of earlier stages in the development of the Universe, which can be seen at great distances, suggests that the Universe has been governed by the same physical laws and constants throughout most of its extent and history. There are various multiverse theories, in which physicists have suggested that our universe is one among many universes that likewise exist. [4] [5] |

The universe is commonly defined as the totality of everything that exists , [1] including all physical matter and energy, the planets, stars, galaxies, and the contents of intergalactic space, [2] [3] although this usage may differ with the context (see definitions, below). The term universe may be used in slightly different contextual senses, denoting such concepts as the cosmos , the world , or nature . Observations of earlier stages in the development of the universe, which can be seen at great distances, suggest that the universe has been governed by the same physical laws and constants throughout most of its extent and history. |

The Universe is everything that physically exists: the entirety of space and time , all forms of matter , energy and momentum , and the physical laws and physical constants that govern them. In a well-defined, mathematical sense, the universe can even be said to contain that which does not exist; according to the path-integral formulation of quantum mechanics , even unrealized possibilities contribute to the probability amplitudes of events in the universe. The universe is sometimes denoted as the cosmos or Nature , as in " cosmology " or " natural philosophy ". |

The universe from a physical or empirical viewpoint is physicists' theoretical and empirical understanding of the philosophical notion of the world , which can naively be described as the sum of all matter and energy that exists and the space-time in which they are located and in which all events occur or could occur. |

The terms known Universe , observable Universe , or visible Universe are often used to describe the part of the Universe that we can see or otherwise observe. Those who believe it is impossible to observe the whole continuum may use our Universe , referring only to that knowable by human beings in particular. |

In the first half of the 20th century , the word universe was used to mean the whole spacetime continuum in which we exist, together with all the energy and matter within it. Attempts to understand the universe in this sense, on the largest possible scales, are made in cosmology , a science that has grown from physics and astronomy . During the second half of the 20th century, the development of observational cosmology , also called physical cosmology , led to a split in the meaning of the word universe , between observational cosmologists and theoretical cosmologists ; where the former (usually) abandon the hope of observing the whole spacetime continuum, the latter retain this hope, attempting to find the most reasonable speculations for modelling the whole of spacetime, despite the extreme difficulty in imagining any empirical constraints on these speculations and the risk of declining into metaphysics . |

The Universe can be defined as "everything that exists". The Universe, proper, is the single largest object with a name, and represents the culmination of full three-dimensional space interacting with time, forming a four-dimensional existence. |
