The area influenced by the gravitational force around planets, stars, and black holes is spherical as they pull evenly in all directions.
Black holes, one of the most mysterious entities in the universe, are often envisioned as perfect spheres that attract everything around them. However, recent discoveries in theoretical physics have led scientists to question: Is the actual shape of black holes as simple as that? This question has opened a vast research journey, ranging from classical physics to advanced theories about extra dimensions, potentially altering our understanding of the universe.
Why Black Holes are Considered Spherical
In the universe as we know it, gravity is the dominant factor that shapes celestial bodies. When massive stars run out of fuel and collapse, they form black holes. During this process, gravity pulls all matter towards the center, resulting in black holes having a shape that closely resembles a sphere.
This also applies to the event horizon, the boundary surrounding a black hole beyond which nothing (not even light) can escape. In a universe with three spatial dimensions (left-right, up-down, forward-backward) and one time dimension, classical physics calculations support the notion that black holes must be spherical.
This formation process is similar to the formation of planets and stars, where gas and dust clouds accumulate under the influence of gravity, compressing into a spherical shape. Thus, the idea of spherical black holes has become a popular viewpoint in astrophysics.
Exploring Higher Dimensions
In recent years, theoretical physics has opened the door to possibilities that go beyond conventional concepts. String theory, one of the most prominent theories, suggests that in addition to the three spatial dimensions we perceive, the universe may include multiple extra dimensions.
These dimensions, while invisible or intangible, could profoundly affect how objects operate in space. In this context, the “spherical” rule of black holes may no longer hold true.
Many advanced mathematical studies have been conducted to determine the possible shapes of black holes in higher dimensions. The results are astonishing: black holes could have entirely different shapes, such as toroidal (like a donut) or other complex structures. This raises a significant question: Are these unusual shapes merely theoretical, or do they actually exist in the universe?
Non-Spherical Black Holes – A Shift in Cosmic Perspective
The idea of non-spherical black holes could change how we perceive the universe. Although there is yet to be direct experimental evidence, these hypotheses open up a new world of possibilities. It is akin to looking through a door we never thought to open, where the universe contains many more surprises than we imagined.
These unusual black hole shapes could provide insights into the nature of gravity in higher dimensions. This is particularly significant for unifying Einstein’s theory of general relativity and quantum mechanics – two pillars of modern physics that have yet to fully harmonize.

Experimenting with Theories
Not stopping at theory, particle physicists are striving to find experimental evidence to verify the existence of extra dimensions. One of the approaches is using gigantic particle accelerators like the Large Hadron Collider (LHC) to recreate high-energy collisions that could produce miniature black holes.
If these black holes are observed, even for a very brief existence, they could confirm the existence of extra dimensions and bring the theory of non-spherical black holes closer to reality.
The Mathematics and Geometry of Black Holes
Over the past two decades, numerous research works have indicated that black holes in higher dimensions could have complex shapes. Calculations show that black holes are not limited to spherical forms but could also possess previously unseen geometric structures.
This raises the question of whether the geometry of black holes can provide information about the fundamental laws of nature. These studies not only enhance our understanding of black holes but also offer a new approach to exploring the nature of spacetime.
The Greater Significance of Discoveries
Exploring black holes not only helps us expand our understanding of a specific cosmic phenomenon. It pushes the boundaries of human knowledge, challenges preconceived notions, and opens new avenues in scientific research.
The intersection of theoretical physics and experimentation, mathematics and astronomy, is gradually bringing us closer to answers to the grand questions about the universe: Is there more than what we can see? What principles govern the universe that we have yet to fully comprehend?
The idea of non-spherical black holes could change how we perceive the universe.
For a long time, the prevailing view was that black holes are always spherical. However, advancements in theoretical physics, along with studies on higher dimensions, have called this notion into question.
While current theories of non-spherical black holes remain theoretical, they have opened a new door to our understanding of spacetime and the nature of the universe. Future discoveries, possibly through particle physics or advanced astronomical observations, will continue to illuminate these mysteries, bringing us closer to understanding the true nature of black holes – and of the universe itself.
