Astronomy 101: Cosmic Rays.

Our planet is constantly interacting with various physical phenomena that affect it from different points of view, causing considerable alterations to occur often; and one of those phenomena are the cosmic rays.

A few things are not correct in your post, if I may.

More specifically, cosmic rays are made of 90% protons, about 8% helium nucleus and a remaining 2% of heavy nucleus such as electrons and antimatter particles (positrons and antiprotons).

Electrons, positrons and antiprotons are not nuclei. Those are different beasts. Whilst a nucleus is connected to a given atomic species, this is not the case at all for the three examples...

It should be noted that there is a variety of these cosmic rays that are ultra-energetic since they move at a speed very close to the speed of light,

Cosmic rays don't need to be ultra energetic to get velocities that are close to the speed of flight. This already occur for much less energetic ones.


This being said, do you know that cosmic rays are at the origins of the development of life on Earth? :)

Cosmic rays don't need to be ultra energetic to get velocities that are close to the speed of flight. This already occur for much less energetic ones.

You are right, I should have specified that the cosmic rays of less energy also travel at speeds close to that of light.

Do you know that cosmic rays are at the origins of the development of life on Earth?

It is to imagine that phenomena like the cosmic rays have originated for thousands of years, only that until now we have been able to begin to understand them.

Somewhere I come to read that many of the evolutionary phases of the human race have something to do with cosmic rays.

Thanks for the tips by the way.

You are very welcome! This post is 1000 times better than the previous one of yours that I have read. I am glad to see the improvements (and we, @steemstem, then supported you :) ).
