The universe has at least another 2.8 billion. years of “life”

Taking into account the way in which it evolves the universe… Portuguese scientists have calculated that the end of “life” is not going to happen until at least 2.8 billion years.
Cosmologists know with certainty that the birth of the Universe placed before 13.8 billion years, from a “cosmic seed” of enormous density began to expand. Astronomical observations have also shown that about 9 billion years later, the expansion began to grow at an accelerated rate.
A scenario for the fate of the universe is that the rate of expansion will remain constant, with the result that in the distant future to stop creating new stars, and to “erase” all of the stars that have formed up to that time, as it will run out of “fuel”.
Then it will disappear and the black holes, due to the radiation that they emit, so that the “world” to be found ultimately in an eternal state of absolute darkness and deep freeze (Big Freeze).
The acceleration of the expansion is attributed by scientists in the dark energy, which acts against the gravity to overwhelm the universe. As the nature of dark energy is unknown, it is likely that the quantity increased progressively with time, which would mean that the rate of inflation will increase at an increasing rate.
In this case, the history of the universe will be completed with the “great schism” (Big Rip), when you will break even and that the space-time continuum.
Earlier forecasts for this scenario mount, this “great schism” is 22 billion years from today. But it could happen earlier?
To answer this question, Diego Σάζε-Gomez and colleagues from the university of Lisbon have created a computational simulation of the cosmic evolution, using the most recent data on the expansion of the “world”.
These data were derived from the displacements of neighbouring stars and supernovae, as well as by “βαρυονικές acoustic oscillations”, i.e. ridges in the distribution of matter in the Universe. With these data, is the study of the behaviour of dark energy.
Based on the computational simulation, scientists found that the more a brief assessment of the “great schism” mount time in about 2.8 billion years from now.
With regard to the most distant time-limit, the model moved to the “great schism” in the infinite, which means that this end never happened, since on the contrary the “world” will end up in the “deep freeze”.
Given that the Sun is not expected to “put out” at least 5 billion years, creates, however, surprising that the universe can complete the “life” so early.
However, scenarios such as the “great schism” comes from the fact that natural science is anything but complete, because, for example, can’t “reconcile” quantum mechanics and the gravitational theory, i.e. the General Theory of Relativity.
Therefore, the time assessment of such scenarios for the “end” of the universe essentially enables scientists to explore an alternative point of view unsolved questions of physics.
