This conclusion was reached by studying global maps of the masses and radii of objects ranging from subatomic particles to superclusters of galaxies.

Scientists at the Australian National University in Canberra have conducted a study suggesting that the Universe may be an upside-down black hole. The results were published in the American Journal of Physics. Dr. Charles Lineweaver and graduate student Vihan Patel have mapped the masses and radii of all objects in the Universe on a global map. Therefore, they have succeeded in finding areas that defy the laws of physics and fall within the field of quantum mechanics. The most prominent feature of the generated logarithmic chart is the black line separating the “no gravity” zone. It contains black holes whose density decreases as their mass increases. Astronomers observed four regions of space and time with strong gravity on the theoretical left side of the boundary, from the remnants of collapsing stars to supermassive ones. This pattern is well established and understood.

What happens beyond this limit has shocked many scientists. Lineweaver and Patel discovered that the observable Universe, lies within the Hubble radius (the region of the expanding Universe surrounding the observer, beyond which objects are moving away from it at speeds greater than the speed of light). bright), coincides with the black line of the hole. . In other words, if a black hole were the same size as the observable Universe, it would have the same surface area. Does this mean the Universe could become a black hole? Scientists admit that many researchers have come to this conclusion in many ways. Lineweaver and Patel chose a mass change that included both dark matter and energy.

As the Universe expanded within the Hubble radius, its mass and energy increased due to the growth of dark matter. In this regard, scientists suggest that a few billion years ago, when the Hubble sphere was much smaller, space was also along the path of the black hole. This suggests the location may not be a simple coincidence. Scientists have shown that around the observable Universe there is an event horizon (a limit in astrophysics beyond which events cannot affect observers), similar to as the limit around a black hole. And this is just the parallel between them.

For the Universe to truly be a black hole, everything outside the Hubble radius must be zero density Minkowski space, i.e. a vacuum. Most cosmologists consider this hypothesis incorrect. “The universe could be an inverted black hole,” Lineweaver added. The researchers concluded that their discovery warrants further consideration, as the consequences and discoveries that creating a global map would bring are not yet completely clear. However, we can say that it opens new paths for science and allows us to learn more about our Universe.
