A cosmic ray is one of the most energetic events in the universe, it travels through any number of light years over millions of years to end up passing through our planet and our bodies; It can also be gamma rays, as well as particles accelerated at speeds very close to that of light, at these speeds we call them relativistic.

We live thanks to the privilege of being close to a star, warm and calm, but not too close and on an iron planet that is basically a giant magnet, which deflects excessive radiation from the sun and has a soup of gases on top, the atmosphere , which protects us from anything that could penetrate, from solar particles to meteorites and that in that soup of gases there is oxygen so that we can breathe.

It makes you think about how lucky we are to be here, literally, it is the VIP seat of the known universe, but there are cosmic rays that have so much energy that they pass through the atmosphere, the ceiling of my house, the slab of the second floor and can keep going through the rocks and the ground below; in 1991 a cosmic ray was detected so energetic that it was called OMG; oh my God, because that was the reaction of the scientists who discovered it.
Another comparison that can be made is that the energy of the OMG particle was the same as that of a baseball ball traveling at 94 kilometers per hour, that is, the energy with which a professional league pitcher throws a ball but concentrated in A single proton, if they throw a ball at you at that speed it hurts and if they hit you in the head it will probably turn off the lights, but that same energy concentrated in a proton makes it move at almost the speed of light taking that inertia.

Although it is believed that cosmic rays also come from jets of matter accelerated at relativistic speeds, called quasars and blazars produced by supermassive black holes that exist in the center of galaxies; There is a curious fact, the supermassive black hole at the center of our galaxy does not produce these relativistic particle jets, because it does not eat enough, for a supermassive black hole to emit its respective quasars and blazars it needs to eat at least the equivalent of three stars like our sun, every day, for the moment, is on a diet, let's hope it continues like this; well up to here, I hope your head hasn't hurt too much, see you soon.
