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.
In astronomy, galactocentrism is the theory that the Milky Way Galaxy, home of Earth ' s Solar System, is at or near the center of the Universe. [1] [2]Thomas Wright and Immanuel Kant first speculated that fuzzy patches of light called nebulae were actually distant "island universes" consisting of many stellar systems. [3]
Hence, it is unclear whether the observable universe matches the entire universe or is significantly smaller, though it is generally accepted that the universe is larger than the observable universe. The universe may be compact in some dimensions and not in others, similar to how a cuboid [citation needed] is longer in one dimension than the ...
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]
The spacetime of the universe is, unlike the diagrams, four-dimensional. The flatness problem (also known as the oldness problem) is a cosmological fine-tuning problem within the Big Bang model of the universe. Such problems arise from the observation that some of the initial conditions of the universe appear to be fine-tuned to very 'special ...
"Our understanding of the universe contains a lot of ignorance about two elements - dark matter and dark energy - and these make up 96% of the universe, so this is no small matter."
The Sun and its planetary system. Cited diameter is that of the Sun's Hill sphere; the region of its gravitational influence.

The universe is so big it's hard to wrap your head around the sheer scale -- it's about 94 billion light-years in diameter, or 546 sextillion miles across. ... largest known to man with a diameter ...
