Johns Hopkins University astronomer and physicist Tommi Tenkanen said: "If dark matter is made up of particles formed before the Big Bang, these particles affect how galaxies are distributed in the sky in a unique way. . This connection can also serve to reveal his identity and bring new elements as to what preceded the Big Bang ”.
The Big Bang did not take place at a specific point, but simultaneously in all directions. And if the Universe does have a center, the observable Universe region that we see is insufficient to give us this information. Any observer can therefore be virtually the center of the Universe, as in this logarithmic scale representation of the Observable Universe, centered on the Solar System. Credit: Pablo
Dark matter (DM) may have its origin in a pre-big-bang epoch, the cosmic inflation. Here, we consider for the first time a broad class of scenarios where a massive free scalar field unavoidably reaches an equilibrium between its classical and quantum dynamics in a characteristic timescale during inflation and sources the DM density.
