Scientists propose a new way to detect the most mysterious substance in the Universe.< /p>
Dark matter, the mysterious substance thought to dominate the universe, has yet to be detected by experiments on Earth. Also, scientists have only indirect evidence of its existence in space. The new hypothesis says that most of the dark matter is concentrated in the form of dense balls that are similar in size to Neptune. Scientists called these objects the planets of dark matter. And you can find them thanks to explosions that resemble a supernova explosion, writes Space.
The fact that dark matter still exists is proved by many observations of the cosmos. But so far it has not been possible to find it directly. This is due to the fact that dark matter very rarely interacts with ordinary matter, or no such interaction occurs at all. A new theory by American scientists says that perhaps dark matter is not distributed evenly throughout the universe, but most of it is concentrated in the form of dark matter planets.
Scientists believe that such objects can be a ball that has a mass equivalent to that of Neptune. And scientists explain how to detect these planets from dark matter in order to directly confirm its existence.
Scientists believe that after the birth of the Universe, even before the appearance of stars and galaxies, dark matter gathered into spherical objects, forming planets from dark matter. As ordinary matter spread throughout the Universe, from which stars and galaxies were formed, all these objects turned out to be gravitationally bound to dark matter planets.
Scientists believe that these hypothetical planets accumulated a layer of helium in the very early universe, and then later accumulated a layer of hydrogen on top of this layer. These two elements were the very first in the newly born universe.
A new theory says that large amounts of helium and hydrogen on dark matter planets could lead to very strong nuclear fusion. As a result, eruptions appear on these planets and the release of matter into space, and sometimes the entire mass of helium and hydrogen can explode. This will lead to the release of a huge amount of energy and radiation, which will be similar to a supernova explosion. The planet itself will not suffer as a result of this catastrophic event, since it is too early for dark matter what ordinary matter does with itself. But scientists believe such explosions could help detect dark matter planets.
Scientists believe that during the explosions there will be emissions of x-rays, which are well known to astronomers. Now it remains only to check the entire catalog of such explosions and the accompanying X-ray fluxes to determine whether dark matter exists and whether it can create special planets.
As Focus already wrote, scientists discovered the oldest dark matter in the universe, which is 12 billion years old. So far, this is only indirect evidence for the existence of this mysterious substance, but scientists believe that it is dark matter that appeared in the very early Universe. We remind you that the age of our Universe, according to modern estimates, is 13.8 billion years.
As for the oldest space objects in the Universe, as Focus already wrote, the Webb Space Telescope was able to break his own record and discovered the new oldest galaxy. This galaxy, according to scientists, existed already 250 million years after the Big Bang. Before that, the Webb telescope discovered a galaxy 300 million years old.
