Atomic clocks in space will help uncover the secret of dark matter: what do they offer scientists

An atomic clock on a spacecraft near the Sun could capture particles of the elusive dark matter.

An international team of scientists have published their new study in the journal Nature Astronomy. In it, scientists propose using an atomic clock placed on a spacecraft that will orbit the sun inside the orbit of Mercury in order to unravel the mystery of dark matter. Scientists offer a new approach to studying the nature of this elusive and mysterious substance, which is believed to make up most of the universe, writes SciTechDaily.

Dark matter makes up more than 80% of the mass of the universe, but so far its particles have not been found on Earth. A key component of these searches is the assumption of the local density of dark matter, which determines the number of its particles passing through the detector at any given time, and therefore, it can be detected.

Scientists believe that the density of dark matter can be much higher than expected, and dark matter may become more concentrated in some regions of space than in others.

One important type of search for dark matter is the search for its particles using atoms or nuclei, because they have the highest sensitivity to dark matter signals. This is possible because, passing through atoms, dark matter particles can cause vibrations in the particles that make up atoms or their nuclei. For example, fluctuations in the mass of an electron or the power of interaction of an electromagnetic force change the transition energies of atoms and nuclei in a predictable way.

An international team of scientists believe that in a certain region of the solar system, between the orbit of Mercury and the Sun, the density of dark matter can be extremely high, which means that atoms or nuclei will be very sensitive to such fluctuations.

According to scientists, dark matter signals will be able to catch atomic clocks placed on a spacecraft in this region of space. This clock carefully measures the frequency of the photons that come out when different states in atoms change. Dark matter near the clock apparatus can change these frequencies, as dark matter oscillations slightly change the energy of the photon.

Scientists believe that the more dark matter there is near the apparatus, the greater these oscillations will be, so the local density dark matter is of great importance. Although the exact density of dark matter near the Sun is not known, scientists say such a search for its particles can provide a lot of important information about this mysterious substance.

As Focus wrote, recently scientists have presented more accurate calculations of the amount of dark matter that exists in our universe.
