The universe is full of dark matter

According to new data, the big bang took place 13.82 billion years ago, still proceeding from 13.75 billion years. And the mysterious dark matter, which does not emit radiation, but by the force of its gravity, for example, holds galaxies, is represented in the universe in greater quantities than has been assumed until now.

From measurements made by "Planck", named after the German physicist Max Planck, it follows that 26.8% of all matter in space is dark matter, and this is almost a fifth more than expected. Ordinary matter, of which the stars, planets and, of course, our Earth, including all living beings, are composed, is represented in the entire space in the amount of 4, 9%.

How could the Planck space telescope make such an amazing "scan" of space? The European probe "combed" with high precision the entire sky in the field of microwave radiation and recorded the so-called background radiation of the Universe.

“Cosmic background radiation is 380,000 years younger than the universe. Thus, it is directly related to the hour of birth of space,”explains Christian Gritzner from the German Center for Aviation and Space.

The residual glow of the Big Bang observed to this day corresponds to a temperature of 2.7 Kelvin, that is, 2.7 ° C above absolute zero - 273 ° C. This heat radiation is uneven. Some regions receive more microwave radiation, others less. This is exactly what the ingenious Planck devices registered.

And before the launch of Planck, other microwave telescopes also scanned space, creating a radiation map. But "Planck" was able to provide a previously unattainable accuracy of the distribution of radiation. Only on the basis of this record resolution data it became possible to obtain new knowledge about the age of the universe and dark matter.

Fluctuations in the intensity of the cosmic background radiation reflect even a slight difference in the density of the past universe. Even then, it was filled with matter unevenly.

New data that contradict the standard model of physics are of great interest to scientists. So, on the background radiation map, there is a fundamental asymmetry between opposite cosmic spheres. This is contrary to the accepted standard model that the universe looks the same regardless of direction.

Also, an inexplicably large cold spot in one of the regions of space. Why is there no microwave radiation coming from there? What happened there in the early universe?

NASA's WMAP microwave satellite has already recorded these mysterious phenomena. But at the same time, we could talk about an error in measurements. Now that these anomalies have been confirmed with great accuracy, scientists should puzzle over them.

Dark energy, this mysterious force responsible for the fact that the universe is not only expanding, but also expanding faster and faster, is reduced in its value, according to the measurements of "Planck". Less dark energy, but more dark matter - this is the result of new dimensions.

Whether the universe really came about as a result of a singular big bang, or, stretching out further, is preserved in order to be born again - it is impossible to figure out from the data obtained by "Planck" so far.

Some scientists hoped to get an answer to this question from a map of cosmic background radiation. Perhaps this will succeed with the next, better measurement. New satellite data will be presented in early 2014.
