Observable Universe is a name for the universe we humans currently inhabit. This includes the individuals who contributed to this wiki. As far as we are aware, our universe is the only observable and measurable space, though this may change in the future.

The Observable Universe contains all of space, time and everything. Currently, the observable universe is 92,200,000,000 ± 140,315,000 light-years across, and makes up 4.9% of the entire universe. However, this number is only of kinds of antimatter we know of, such as dark matter and energy. The actual size of the universe, due to other kinds of undiscovered antimatter, is actually over 160-sextillion times the size of the Observable Universe. This means that if you were to place a light bulb on Pluto, Pluto would accurately represent the size of the universe as the light bulb would represent the size of the Observable Universe. However, it's expanding at over the speed of light, so does it change? No, because our units are ever-so-slightly expanding with it. The universe is currently thought to be 13,787,000,000 ± 20,000,000 years old, yet the oldest star, HD 140283 is thought to be 14,460,000,000 ± 800,000,000 years old. What's up with that? Scientists are finding out it is less and less old than previously thought. A universe could be described as an independent segment of possibility; a bubble of space with a defined beginning point (typically a Big Bang) and a set of physical laws, which may or may not line up with the ones humanity observes. The only thing aside from a vecoverse that can be before the Universe is the Law of Dimensional Cycle.


Our universe is contained in a multiverse along with other multiple (and probably alternate) universes - perhaps an immeasurable number - which may or may not contain humans or life at all. In fact, some of them may be so hostile, and chemistry or physics as we know them, may not function properly. The possible total number of universes in our multiverse, based on the probability law, reach as high as 10^10^10^122 megaparsecs, as implied by a suggested resolution of the No-Boundary Proposal.

Our universe was involved in a collision 13,786,620,000 ± 21,000 years ago. In the southern southeast universe, in an oval stretching across 1,800,000,000 light-years, there is a spot slightly colder than the regular universe, that is devoid of what should be an area of about 10,000 galaxies. It is only 0.00015°C colder than the rest of the universe, but that is much colder on a scale of space temperature. Why does this spot exist? It is due to this universal collision! All the galaxies were sucked up from that area into the other universe, and the area gradually grew colder over time. The laws of physics were somewhat changed, and into what they are today. The collision would look like an extremely cold mirror coming towards you, and then that mirror suddenly catching on fire and burning. Everything in the area would be sucked into the other universe, and everything in the other universe’s area of collision would be sent into ours. The universe could have been much colder or older than ours, causing the area to be frozen. Thermodynamic equilibrium would most likely have started making the area warmer, turning it into what it is today.

Other Information

Most universes, including ours, shall eventually "die" as the second law of thermodynamics ensures that energy becomes less and less usable over time. This universe is also the least confusing to understand, as it is the only one that we know exists so far.


Our universe starts in a big bang with quantum foam at Planck Temperature, to create space-time. Eventually, this comes together in large numbers to form gluons. These gluons can eventually form into quarks, which create protons and neutrons. Protons come together, sometimes with neutrons, to form atoms, the basic building blocks of all material. These atomic nuclei also form electrons around them to propel against protons. This forms an atom, the basic building block of all material. The first atom is hydrogen, but then helium atoms form. And soon, so do lithium, boron, carbon, oxygen, nitrogen, sodium, and many more! These start forming meteors, then asteroids, and planets. Eventually, some planets grow large, becoming a star. Nearby planets get pulled into orbit, creating a planetary system. This eventually forms star clusters, which form galaxies. These form galaxy clusters, which form superclusters. these form huge cosmic webs, covering about five percent of the observable universe.

"Panoramic view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way. The image is derived from the 2MASS Extended Source Catalog (XSC)—more than 1.5 million galaxies, and the Point Source Catalog (PSC)—nearly 0.5 billion Milky Way stars. The galaxies are color-coded by 'redshift' obtained from the UGC, CfA, Tully NBGC, LCRS, 2dF, 6dFGS, and SDSS surveys (and from various observations compiled by the NASA Extragalactic Database), or photo-metrically deduced from the K band (2.2 μm). Blue are the nearest sources (z < 0.01); green are at moderate distances (0.01 < z < 0.04) and red are the most distant sources that 2MASS resolves (0.04 < z < 0.1). The map is projected with an equal area Aitoff in the Galactic system (Milky Way at center)."
