Physicists are studying the “bubble of nothing” which could destroy our Universe
Source:
Whether to devour itself from the inside? Fortunately for us, physics that studies the phenomenon called “collapse of space-time”, I think it is unlikely. The idea that the universe can be completely destroyed by the expanding bubble of emptiness were expressed in 1982 a theoretical physicist named Edward Witten. In a paper published in the journal , the scientist introduced the possibility that the universe will swallow itself. In space, according to physics, should be formed spontaneously hole, which will be expanded indefinitely, until you absorb everything that gets in her way. Sounds pretty creepy, but could it happen in reality?
In search of a new “theory of everything”
As a mysterious bubble of nothing is still not destroyed our Universe, scientists are quite rightly considered this scenario unlikely. But physicists from the University of Oviedo in Spain and the University of Uppsala in Sweden in his work, published in the journal argue that the idea of Witten teaches important lessons. In particular, it is about understanding the context of the collapse of space-time through the bubbles of nothing. According to the study authors, this theory is a step towards connecting the smallest building blocks of the Universe – string – theories about space and time.
The fact is that our universe is so complex that most of it is in vacuum, which allows it to exist in a relatively stable condition. According to quantum field theory, which connects quantum physics and the dynamics of space-time is the minimum possible energy state. For this reason, we should not worry about the decay of space-time. However, in theoretical physics these assumptions by themselves are rarely sustainable. Thus, the possibility that the stability of our Universe is an illusion, opened a number of questions about how and why the vacuum can decay. “Bubble of nothing” – one of the possible answers.
What is a bubble from nothing?
As written , the bubble of nothing describes the variant «the destruction of the Universe», in which the bubble expands and can absorb all of space-time, turning it into «nothing». But what is a bubble from nothing? Researchers believe that there can be «bubble of space-time» inside and outside which has different properties. If the illusory space of the vacuum is suddenly formed bubble of nothing, then it will grow until you engulf the entire Universe. But why?
the Existence of a bubble from nothing is possible if string theory is correct
The Answer lies in “string Theory”, which unites the phenomena of quantum physics with the behavior and effects of gravitational fields. Recall that string theory is studying the dynamics of the interaction are not point particles but one-dimensional extended objects – quantum strings. However, the mathematics of string theory only works if there are more than four dimensions: three spatial dimensions, a time dimension, and then the many other dimensions that are so small that they can only be detected mathematically. In General, in the geometry of our Universe appears four-dimensional space-time just because extra dimensions are tightly compressed and hidden. That's why the bubbles of nothing would be formed in four-dimensional space-time, but will be formed in the “slow” multidimensional space-time.
Theoretically, the bubble of nothing will grow until you engulf the entire Universe.
Unexpected properties of the bubble from nothing
Despite the fact that all of the above applies to theoretical physics, the study authors believe that the mathematical description destroy the bubble universe out of nothing can also be used to simulate the origin of the Universe. The researchers note that as the bubble expands, the observer can see that could explain the origin of the mysterious dark energy. Anyway, you clearly can not worry about the fact that our universe will consume itself with a bubble of nothing, but research in this area can really help scientists in discovering other mysteries of the Universe and finally learn how the universe looked after the Big Bang.
