The study of an international team of scientists corroborates the assumption of the existence of the so-called – primordial black holes.
Unlike supermassive black holes, which are formed from stars, ANPs are hypothetical formations. It is hypothesized that they were born during inflation, one of the first phases of the universe when it expanded rapidly after the Big Bang , explains a statement from the Kavli Institute for the Physics and Mathematics of the Universe in Japan, released on December 24.
During this stage, the density of matter should be so great that a fluctuation that increases it by 50 percent would be enough for a “baby universe” to form, which eventually collapses and reintegrates the main universe. This event generates so much energy that it can cause a black hole to appear.
During this stage, the density of the material should be so great that a fluctuation that increases it by 50% would be enough for a ‘baby universe’ to form , which over time collapses and reintegrates the main universe. This event generates so much energy that it can cause a black hole to appear.
A fascinating conclusion from Einstein’s theory is that if the ‘baby universe’ is large enough , it can be viewed in different ways to internal and external observers. From the outside, it would look like a black hole, while from the inside it would be seen to be expanding. In this way, it would be the situation in which several universes exist simultaneously, or ‘ multiverse’.
In their article , published in the Physical Review Newsletter, the researchers support this hypothesis with calculations and present a new scenario, stating that behind the appearance of primordial black holes could be vacuum bubbles that formed during the inflation phase. . Likewise, they assert that ANPs can explain “simultaneously all the black matter, [the gravitational waves] observed and also provide seeds for supermassive black holes . “
As for the empirical testing of the hypothesis, the scientists indicate that ANPs can be detected with quite strong telescopes. If a black hole passes between the Earth and a distant sun, it distorts the light emitted by the star. Based on the duration of the effect, the researchers can calculate the mass of the ANP. A possible event of this type has already been detected by the Japanese Subaru telescope, located in Hawaii.
