Dark matter is made from black holes

New research by American scientists shows that dark matter is produced from the original black hole, which appeared in the first millisecond after the Big Bang.

According to the Daily Galaxy, the majority of theories claim that dark matter is a form of existence of large amounts of matter but the most difficult to detect in the universe. Accordingly, the universe is made up of 5% of the ordinary matter we see, 27% of dark matter, and 68% of dark energy. Recently, scientists hypothesized that dark matter formed by primitive black holes appeared at the first moments of the universe.

In the new study published on May 24 in Astrophysical Journal Letters, Alexander Kashlinsky, a scientist at the Goddard Space Center of the US Aeronautics and Space Administration (NASA), proved this hypothesis to be consistent with understanding. Our knowledge of infrared and X-rays in the universe. At the same time, this hypothesis helps explain the unexpectedly large volumes of merged black holes found last year.

"If this is true, then all the galaxies, including our Milky Way, are in a giant sphere of many black holes, each of which has about 30 times the mass. with the Sun, " Kashlinsky said.

In 2005, Kashlinsky led a team of astronomers using NASA's Spitzer space telescope to explore the infrared (CIB) sky. The researchers found signs of the first light source lighting the universe more than 13 billion years ago. In 2013, another X-ray background study (CXB) was measured by NASA's Chandra Observatory for purposes of comparison with Kashlinsky's CIB results.

In theory, the first stars primarily emit optical light and ultraviolet rays. Part of this is transformed into infrared rays due to the expansion of the universe. Therefore, the CIB signal spectrum may contain noise information while the CXB spectrum may eliminate this.

The results show that unusual light of low-energy X-rays in the CXB spectrum coincides with the same signals in the CIB spectrum. This means these light comes from a single object, and only primitive black holes can radiate on such a wide range of energy.

Kashlinsky also suggested that primitive black holes alter the mass distribution of the universe in the first seconds, causing changes that its consequences occurred hundreds of millions of years later, when the first stars caught early formation.

At this time, most ordinary matter in the universe is too hot to form the first stars. Dark matter is not affected by high temperatures because it interacts through gravity. They reassembled by attracting each other, forming small halos, an attractive particle that allows ordinary matter to bind together. The hot gas is now drawn towards the small halos, forming dense air pockets, and continues to grow into the formation of the first stars.

If primitive black holes are involved in forming dark matter, the fusion of gases will take place faster and manifest with ripples in the CIB signal spectrum recorded at Spitzer.
