«Galactic radiation» — «Галактическое излучение»

Описание: A minute fragment of a very long track in the style of classical electronica (sometimes such music is attributed to the Berlin electronic school), which opens the album "Oort Cloud". There are 4 tracks in total - some longer, some shorter, but approximately in the same style.

In the meantime, I’ll say a few words about the title – «Galactic radiation».

Astronomers know what it is only theoretically. Because we live inside a protective bubble called the "Heliosphere". It is created by the Sun with its radiation, emanating from it in all directions approximately equally. At a distance of about 100 astronomical units (2.5 times further than Pluto), the flow of solar radiation begins to be balanced by the combined flow of various types of particles from all the stars of the Milky Way Galaxy. And a shock wave is formed. Galactic radiation stops at this point and practically does not get inside the Heliosphere. And we cannot observe it, measure it, study it in any way. But this can be done by spacecraft that have left the Heliosphere - Voyager 1 and Voyager 2, for example. They are poorly suited for this, since they were launched for other studies. In addition, they are already very old. But apart from them, no one can tell us about galactic radiation.

Although, no. Someone can tell.

Comets, flying in from the farthest edges of the Solar System. Their icy cores have been dormant in the Oort Cloud for billions of years, under the constant influence of (rather harsh, as scientists assume) galactic radiation. One day, something disrupted their movement along a distant orbit, and, having lost its balance, such a block of ice rushed into the inner part of the Solar System. About once a year, something like this flies to us. This is normal. This is common. It would be unusual if suddenly hundreds or thousands of icebergs from the Oort Cloud visited us at the same time. But this has happened in the history of the Earth. The consequences were not the best - a significant part of the Earth's biosphere then suffered greatly - from a collision with a cometary core much more massive than the one that caused the Tunguska phenomenon.

The comets that fly from the Oort Cloud today have almost zero chance of hitting Earth. They usually pass hundreds of millions of kilometers from our planet. But astronomers can learn something about them even from such a great distance.

First of all, it is indeed ice - frozen, but familiar to us water. The isotopic composition is close to the composition of water in our oceans. And this suggests that the water on Earth (and on the Moon, and on Mars, and even on Mercury - in its polar regions) may have a cometary origin - comets brought it.

And along with water, the first organic matter came to Earth from comets. Comets are full of organic matter. It is not particularly complex - alcohols, hydrocarbons, urea, cyanides... but still, it is a good broth for the formation of more complex structures, from which life can then arise. By the way, in interstellar gas and dust clouds (and the Sun regularly passes through them - together with the Oort Cloud, which absorbs the environment like a sponge) something more complex has been found - right up to RNA molecules. Here, primitive life is just a stone's throw away.

For us - here on Earth - primitive life is also a stone's throw away. We only have to relax and stop developing. Degradation will quickly return us to our origins and primitive traditions.

Where could organic matter come from in the comet cores of the Oort Cloud?

Its synthesis is greatly facilitated by the same galactic radiation, or galactic radiation. In general, it is more energetically powerful than solar radiation. Because the Galaxy contains many stars that are hotter and more active than our Sun. The radiation of these stars easily ionizes matter - both in interstellar clouds and in the surface layer of comet cores. And the ionized atom immediately goes in search of someone to merge with in order to compensate for the loss of an electron caused by galactic radiation. Thus, those chemical reactions become possible that do not occur in inorganic chemistry by themselves - galactic radiation becomes a catalyst for them.

The cold environment and the ever-growing ice make the Oort Clouds an endless repository of potential biomaterial. It's just waiting for a chance to fall inward - to the warm Sun, to one of the planets. And then - as luck would have it.

One day we got lucky.

The most striking thing about this story is that the same phenomenon can be both the cause of life's appearance and the cause of its disappearance. And it can also be the cause of something else that is still unknown to us
