Scientists Have Mathematically Discovered a Bomb Under the Universe
USA — August 2, 2018
According to new research published in The European Physical Journal the future of our universe could be much more unstable and possibly catastrophic than previously believed.
At the turn of the 21st century, space science made a number of important discoveries, such as indirect proof of the universe's inflationary expansion, dark matter and dark energy, gravitation waves and more. In 1998, it was found that the universe was expanding at an accelerated rate.
Scientists believe that the acceleration is caused by the so-called "dark sector" of the universe. Observations have shown that well-known baryonic matter is just 4.9% of the universe, with the "dark sector" composed of the mysterious dark matter (26.8%) and even more mysterious dark energy (68.3%) accounting for the remaining 95.1%.
"Regard for a new class of singularities (infinite state of a parameter) makes our universe's future unpredictable and dangerous. This research indicates that certain singularities could emerge suddenly and practically at any time. Neither stars nor even galaxies would survive a disaster like this," said BFU Professor Artyom Yurov, a co-author of the research.
It is not yet known what dark energy is. There are three main hypotheses concerning dark energy. The first one has it that dark energy is a cosmologic constant, that is, invariable energy density that is evenly distributed across the universe. The second hypothesis defines dark energy as a quintessence or a dynamic field whose energy density varies in space and time. The third hypothesis assumes that dark energy is a manifestation of modified gravity at distances reaching the order of the visible part of the universe.
"The future of the universe depends on which of these models is true. If the second hypothesis is correct and dark energy is really a quintessence, then the future may hold a lot of amazing and unpleasant surprises. In particular, singularities are likely to appear during accelerated expansion! For example, the medium pressure of the quintessence could suddenly 'explode'," Mr. Yurov said.
A more extensive mathematical study of this enabled physicists Sergei Odintsov, Shinichi Nojiri and Shinji Tsujikawa to classify possible catastrophic singularities.
There is a classification of singularities described by scientists for today. For example, Cambridge University Professor John Barrow made calculations in 2004 showing that a catastrophic event like this was possible. A team of BFU physicists has mathematically proved that there can be a whole class of singularities that have not yet been described. This means that our universe could suddenly perish because of singularities with a specific potential of the scalar field or if the character of the singularities unexpectedly change.
