Dark energy is a false problem?
In the first part, we spoke about the potential of dark energy and its consequences in the Universe. Now, we will continue the article with more details about the dark energy.
Starting from the so-called absolute transformation Lorentz and suitably selecting a preferred reference system, relative to which one has the time dilation directional (for example, the inertial reference system centered on the non-rotating Earth, which currently is used to calculate the dilation the times of the GPS satellites), Kipreos believes that a precise application of the Lorentz transformation absolute cosmological data could have significant implications for the evolution of the universe and the existence of dark energy.
As the Universe expands, the cosmic structures, such as galaxies, move away much faster relative to each other in a process known as Hubble expansion. The absolute transformation Lorentz indicates that the increase in speed causes a time dilation directional. If you apply this transformation to the increased speed, which are associated to the expansion of the Universe Hubble today, you get a scenario in which the present suffers a time dilation relative to the past. In other words, the passing of time would be slower in the present and faster in the past.
The two figures illustrate the variation of the brightness of type Ia supernovae function of the distance, expressed in terms of redshift. On the left shows the current data of the SN Ia while on the right the same data were corrected for the effect of relativistic time dilation according to the hypothesis of Kipreos.

So what are the consequences for the concept of dark energy? If we consider the supernovae exploding with the same brightness, they are used by astronomers as “standard candles” to measure cosmological distances. Those which are relatively close to Earth are aligned on a graph that gives the variation of the distance, obtained from the redshift, according to the brightness. In 1998, the study of distant supernovae provided the observational evidence that the pace of the cosmic expansion has accelerated in the last 5 billion years. “The accelerated expansion of the Universe has been attributed to dark energy. However, we do not know anything about its nature nor do we know why it is manifested only recently in cosmic history. The effects provided by the fact that Time would pass more quickly in the past could cause the graph of supernovae becomes linear on all cosmic distances, which would imply that there is no acceleration of the cosmic expansion. In this scenario, therefore, there would be no need to invoke the existence of dark energy, “concludes Kipreos.
We requested an opinion to Alessandro Melchiorri, a High Energy Theory Group at the University of Rome La Sapienza, cosmologist and expert in particle astrophysics and quantum gravity: “Sometimes not experts try to explain everything at once with new outlandish theories. A more humble and aware of the situation experimental and theoretical current could avoid similar outputs. I do not believe that this work deserves special attention.”
