Scientists: Something Existed Before Our Universe

According to the generally accepted theory of the Big Bang, the universe began with a singularity - a state in which

all matter and energy were compressed into one point.Then space expanded to enormous proportions. But the Big Bang theory does not explain what happened before the singularity, so this state cannot be described from the point of view of the laws of physics and mathematics.

Pennsylvania State University scientiststake a different point of view: the Big Bounce hypothesis, according to which our expanding universe arose from the supercompressed mass of the universe of the previous phase. To describe this state, they use a universal mathematical apparatus that combines quantum mechanics and the theory of relativity.

In a new study, scientists argue that, from a loop quantum cosmology perspective, describing inflation removes two major anomalies in the CMB distribution.

Using the quantum loop cosmology, wenaturally resolved two of these anomalies, thus avoiding a potential crisis. The presence of these anomalies suggests that we live in an exceptional universe.

The authors believe that the heterogeneity of the relictradiations are the result of inevitable quantum fluctuations in the early universe. During the accelerated expansion phase, which we already mentioned, these initially tiny fluctuations were stretched under the influence of gravity, reflected in the observed irregularities.

The findings of American scientists can confirm orrefute new satellite missions such as LiteBIRD and Cosmic Origins Explorer: they are aimed at detecting traces of primordial gravitational waves in the background of the cosmic microwave background radiation.
