Is the Universe a Big Black Hole?

A team of scientists from the Australian National University (ANU) developed the most complete view of the history of the universe ever created and offers new insight into how our universe may have begun. It’s the most complete chart of the universe, and everything from subatomic particles to galaxies and even superclusters appears. The interesting thing about this large atlas of objects of the universe is that raises a lot of interesting questions.

“When the universe began.” 13.8 billion years ago With the hot big bang, there were no objects like protons, atoms, people, planets, stars or galaxies. Now the universe is full of objects of this type,” explained Charley Lineweaver, the study’s leader, in a press release. “The relatively simple answer to its origin is that As the universe cooled, all these objects condensed from the hot background“.

Understanding the origins of objects

To put this explanation into perspective, the researchers created two graphs: one shows the temperature and density of the universe as it expanded and cooled; The second graph shows the mass and size of all objects in the universe.. what do we get The most complete chart ever made of all objects in the universe, published in the latest issue of the journal American Journal of Physics.

The radius versus mass graph has parts where there is nothing: a series of black holes of various sizes separate objects in space from the “gravity-forbidden” part, while a smaller part towards the bottom is “forbidden”.“because of the uncertainty principle the quantum or Heisenberg uncertainty principle, formulated by the German physicist and Nobel Prize winner Werner Heisenberg in 1927, which says that we cannot know both the position and the velocity of a particle such as a photon or an electron with perfect accuracy; The more we determine the position of a particle, the less we know about its speed and rate of rotation…

So as time goes on that uncertainty extends into the future, which leads to a physical state that cannot be known arbitrarily. The position and velocity of an object cannot be measured exactly at the same time, even theoretically. Therefore, certain regions are “off limits” according to known laws, or where “quantum mechanics erases the very essence of what it really means to be a singular object”. We could say that exact position and exact speed together have no meaning in nature.

“Parts of this graph are ‘off limits’: objects cannot be denser than black holes or so small that quantum mechanics it erases the very essence of what it really means to be a unique object” comments another of the researchers, Vihan Patel.

Could the universe be a black hole?

Continuing on the graph, black holes are dotted along this “gravity-forbidden” line, with the largest black holes being the lowest-density ones. The line extends upward, indicating the entire observable universe within “radio de Hubble”, It is also in this line. This suggests that if a black hole were as large as the observable universe, it would have the same density as the universe itself. So, Is the universe itself a black hole? The chart allows for such an interesting question. Since the universe has always been on the edge of black holes, it suggests their position on the line may not be a mere coincidence.

This is what experts point out There is an event horizon around the observable universe, just as there is an event horizon around a black hole, and this is only one of the parallels between them. However, since we still don’t know what the inside of a black hole is like, we have nothing to compare it to. For now, everything remains a big mystery.

“At the smallest end, where quantum mechanics and general relativity meet, is the smallest possible object: instanton. “This graph suggests that the universe may have started as an instant that has a specific size and mass, rather than a singularity, which is a hypothetical point of infinite density and temperature,” says Patel. “Generally speaking, the plot suggests that if there were nothing (a complete vacuum) behind the observable universe, our universe would be a large, low-density black hole. It’s a bit scary, but we have good reasons to believe that this is not the case,” concludes the expert.
