The center of the Universe is a concept that lacks a coherent definition in modern astronomy; according to standard cosmological theories on the shape of the universe, it has no distinct spatial center. Historically, different people have suggested various locations as the center of the Universe.
Assuming a finite universe, the universe can either have an edge or no edge. Many finite mathematical spaces, e.g., a disc, have an edge or boundary. Spaces that have an edge are difficult to treat, both conceptually and mathematically. Namely, it is difficult to state what would happen at the edge of such a universe.
The universe's size is unknown, and it may be infinite in extent. [14] Some parts of the universe are too far away for the light emitted since the Big Bang to have had enough time to reach Earth or space-based instruments, and therefore lie outside the observable universe. In the future, light from distant galaxies will have had more time to ...
A concrete circle at the apex of a rebuilt span of the old Boston Avenue viaduct, between 1st and Archer Streets, in Tulsa, Oklahoma is known as "The Center of the Universe". The spot produces an acoustical anomaly [13] and it is for which the Center of the Universe Festival and Ms. Center of the Universe Pageant are named. [citation needed]
At still larger scales (over 1000 megaparsecs [a]) the Universe becomes homogeneous, meaning that all its parts have on average the same density, composition and structure. [ 7 ] Since there is believed to be no "center" or "edge" of the Universe, there is no particular reference point with which to plot the overall location of the Earth in the ...
After Shapley and Hubble showed that the Sun is not the center of the universe, cosmology moved on from heliocentrism to galactocentrism, which states that the Milky Way is the center of the universe. [157] Hubble's observations of redshift in light from distant galaxies indicated that the universe was expanding and acentric. [159]
The universe appears to have much more matter than antimatter, ... that at the center of the universe was a "central fire" around which the Earth, Sun, ...
The Galactic Center, as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image. Marked location of the Galactic Center A starchart of the night sky towards the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy.
