The Largest Singular Object in the Universe Beyond Stars and Black Holes

When discussing the largest singular object in the universe, traditionally, one might consider supermassive stars or black holes. However, in the vast expanse of the cosmos, there is a broader perspective to explore. This article delves into the concept that beyond these conventional giants, the largest singular object is none other than the universe itself as a connected, entangled existence.

Existence as a Unified Singularity

The observable universe, despite its vastness, is not composed of discrete, impermeable objects. Instead, it is a interconnected field of interactions. This interconnectedness leads to the postulated notion that every Higgs boson is mutually quantum entangled, suggesting that the entire observable universe can be considered one grand, unified entity.

From a philosophical and theoretical physics standpoint, the universe can be seen as a singular, 4-dimensional reference point - a relative existence singularity. This perspective transcends the individual objects that populate the cosmos, treating the collective as a single, interwoven object.

Extragalactic Filaments: The Largest Object in Space

For those who prefer a more definitional approach to what constitutes an 'object', the largest entity is undoubtedly the extragalactic filaments that make up the cosmic web. These filaments, extending hundreds of millions of light-years, form along channels of dark matter, connecting hundreds of billions of galaxies across the cosmos.

The extragalactic filaments are no less remarkable in their individuality. They serve as cosmic highways, illuminating with their gravitational influence. At the points where these filaments converge, there are galaxy clusters. Conversely, the spaces between the filaments are vast voids, regions where galaxies are sparse.

As a finer detail, consider the visualization below, which shows the absolute magnitude of the filaments, with an overlaid square representing a 10 million light-year span. The image captures the extended gas between galaxies, illuminated by the birth of a quasar.

This quasar is illuminating diffuse gas on scales well beyond any we've seen before, giving us the first picture of extended gas between galaxies. It provides a terrific insight into the overall structure of our universe.

Other Candidates for the Largest Object in the Universe

While extragalactic filaments stand as the most prominent candidates, there are other contenders that deserve mention. For instance, extragalactic magnetic filaments, the magnetic filaments of the Milky Way, protostellar disks, and nebulae, all present intriguing alternatives. Additionally, phenomena such as gamma ray bursts from hypernovas or black holes, and supermassive compact objects, offer further complexity and dimensions to the discussion of the largest singular object in the universe.

Edit: Here is a shortlist of other candidates:

These candidates, though fascinating in their own right, often lack the scale and interconnectedness of the extragalactic filaments in defining the largest singular object in the universe. In conclusion, while the universe itself is a unified singularity, the extragalactic filaments serve as a visible manifestation of this interconnectedness, making them the largest object in the universe in a practical sense.
