There is nothing more triumphant for a scientist than the moment when theoretical calculations are confirmed by practical research. Especially if between them lies several decades of improving technologies and tools. Even in the last century, astrophysicists guessed that most of the real or baryonic matter should be concentrated somewhere between galaxies and stars. But it was possible to make out her only today.
To understand the scale of the discovery: according to the current model of the universe, the Universe is 95% composed of mysterious dark matter, plus dark energy, and the remaining 4, 6% is ordinary matter, familiar to us, of electrons and protons. But when scientists calculated the amount of matter in stars, hot gases of galactic clusters and in the interstellar medium, it turned out to be 50% less than necessary. Where is the rest hidden?
It turned out that the substance is there, but because of the prohibitively low density it is impossible to "see" it. I had to use the Sunyaev-Zeldovich effect, which describes the changes in the glow of the relic radiation when interacting with the hot, but invisible gas of interstellar voids. Data from the Plank orbiting observatory for 260, 000 pairs of galaxies showed that thin filaments of gas stretched between them, in which the missing 50% of real matter is concentrated.
Scientists not only found the allegedly missing matter of the Universe, they once again confirmed and refined the model of its device. A multidimensional system with large and small nodes created by gravitational forces, between which invisible stable connections stretch. Fundamental theories, some of which are more than half a century old, are being confirmed - we are all getting to know better how the world around us works.
