Are there parts of the universe that we will never know?

The graph below has been created by researchers from the Australian National University and in it they have represented all the objects in the universe from the smallest to the most enormous, from the quantum world to colossal black holes. It seems simple, but it is extremely complex. .

This work was published on October 18 and is not only one of the most complete guides to the history of the universe, but also raises the astonishing hypothesis of the possibility that the observable universe where we live could actually be what it is. inside a black hole.

The lead author of this graph and the study is Honorary Associate Professor Charley Lineweaver of the Australian National University, who literally stated that “When the universe began 13.8 billion years ago with a hot Big Bang, there were no objects such as protons, atoms, , people, planets, stars or galaxies. Now the universe is full of objects of this type,” explained Charley Lineweaver, so what the researchers asked themselves is how this is possible.

A relatively simple answer is that as the Universe cooled, all those objects condensed from that primordial energy, from that hot background, first the subatomic particles condensed, then the hydrogen atom was formed, which is the most simple, then the stars, planets, etc.; To show this formation process in the simplest way possible, the researchers have made two lines within the graph.

The first shows the temperature and density of the universe as it expanded and cooled, the second traces the mass and size of all the objects in the universe. In that scheme there are two zones that are prohibited. Forbidden zones is the term. that researchers use, although the most correct thing would be to say that they are areas that are not unknown or that we do not have the tools to explore them.

Here there is also a fundamental question, a debate that is also old and there are parts of it in the universe that no matter how hard we try we will never be able to know, it is a question that has also been raised and debated for a long time.

These prohibited parts are two, one is when the density of the event horizon of a black hole is exceeded and the other part is the part that is so small, so small that quantum mechanics blurs it and the very nature of what is a singular object lacks already meaningless, because it is so incredibly small, so basically the forbidden zone would be what is inside the black holes that we do not know what there is and the other prohibited zone would be what is smaller than the smallest known.
