A new approach to calculating the density of dark energy was proposed by physicists from the Immanuel Kant Baltic Federal University, RIA News reports. The research is published in the Symmetry journal. According to the authors, the results obtained will probably help explain some of the anomalies of this phenomenon and better understand why the universe is expanding with acceleration.
Physicists of the university have proposed a new method for calculating dark energy using the so-called “holographic principle”. This principle is closely related to the cosmological event horizon, a special boundary that even light cannot cross.
According to the holographic principle, or the so-called Bekenstein constraint, the maximum information that can be placed in a certain region of space is determined not by its volume but by the surface area in which this volume is enclosed. As physicists clarify, Einstein’s cosmological equation can be written as an eigenvalue problem and their role will be played by the lambda term.
“To solve such a problem, it is necessary to use the so-called ‘boundary conditions’. Our key idea is that the boundary conditions should be related to the holographic principle: the number of bits contained in the universe is equal to the maximum value allowed by this principle. This makes the task of finally calculating the lambda term much simpler and more concrete, and we did it for an arbitrary number of spatial dimensions,” the Director of the Institute of Physical and Mathematical Sciences and Information Technologies of the Baltic Federal University, Professor Artem Yurov, explained.
