Black holes are the most mysterious and terrifying celestial bodies that can be found in the Universe . According to cosmological calculations, the oldest black holes should have “swallowed” the entire Universe long ago, but this has not happened, but why? Let’s see next what is the crazy and possible explanation why black holes do not swallow the entire universe.
Why don’t black holes swallow the whole universe?
There is no clear and valid reason why this hasn’t happened yet, and it is one of the most curious questions that scientists and astrophysicists have been searching for an answer to for some time. Black holes, some of which are even billions of years old, continually swallow and engulf matter, in such an absurd way that even light and space are trapped in them. If they are capable of engulfing space itself, why haven’t they expanded to cover the entire universe?
This question was answered (or at least attempted to do so) by one of the most important physicists of recent years, Leonard Susskind, a researcher on the much-talked about ” String Theory .” Whenever matter is added to any object, it is expected to increase in size outward, becoming larger and larger. However, according to Susskind, black holes may have the extraordinary ability to become more complex “inward,” not outward .
Although it may seem an impossible to imagine / understand and almost intuitive statement, it is possible that the theory hides a grain of truth , and it would explain not only the behavior of these space hearts of darkness, but it could also serve to confirm some hypotheses of the string theory.
The biggest problem with this thesis is that it is practically impossible to verify it: there is no way to verify what happens inside a black hole (at least as far as our scientific development allows us today).
A key to get out of this impasse could therefore be to find a new way of understanding Physics and Cosmology , in particular, trying to marry those two branches that today still do not always get along: Quantum Mechanics and Relativity. General (precisely what to try to do with string theory).
Probably this question (and like many others on the subject of “space-time”) will continue to haunt us for many years, but it is never wrong to ask the right questions and seek equally correct answers.
