On November 25, research was published and the world of science literally began to shake, because it could be the first direct signal of dark matter and it would also change the rules of the game. What is this about dark matter? The astrophysicist Fritz Zwicky proposed it almost 100 years ago.
Dark matter is not dark, I wish it were, because if it were dark, then we could see it in contrast with something of a luminous color, the bad thing is that it is invisible, it does not shine, nor does it react with anything, it does not emit light, we cannot capture it with any of our telescopes, nor radio telescopes, or anything, but we know that it is there, that there is something there, something there that has mass and has therefore that gravity also affects it.
We know that there has to be a lot, five times more than normal matter, and dark matter is not normal matter, it is not any of the atoms of the periodic table, it is nothing known, it would be something completely abnormal, abnormal because we do not know it, although within what the universe is it is five times more than what we know, so, perhaps the abnormal ones are us who are made of normal matter, from our point of view, but from the point of view of the universe, no, because there is five times more dark matter than matter we call normal.
But as far as we know, dark matter exists, because it does things, it acts as a gravitational cement for everything we see, if we only had the stars, planets and the gas and dust that we see, that we know, which are made of normal matter with the elements of the periodic table, the galaxies would end up falling apart and the stars would end up scattered everywhere, it is like spinning a hammer quickly in the hammer throw and letting it go, but that does not happen. Therefore, for many years it has been assumed that there is something with mass that provides gravity so that everything we are seeing is more or less ordered.
There has been speculation about everything from particles that travel faster than light, primordial black holes, to the fact that dark matter does not exist and that what we see are the effects that would be explained by gravity acting differently at great distances. Why should gravity act differently? Well, it is the part that does not explain that theory, but we do not have to be very demanding either, all the previous theories also have holes and to fill them in we need to obtain evidence and that is what seems to have been achieved now.
Professor Tomonori Totani of the University of Tokyo and did it using data from NASA's Fermi space telescope, Tomonori Totani analyzed gamma ray emissions in the central region of our galaxy and what he did was detect an excess of gamma rays with energy of approximately 20 gigaelectronvolts within the structure of the galactic center of a single photon, what they have detected is light, they are photons, those photons come from these special gamma rays that are produced in an extraordinary amount that cannot be explained in any way. normal, hence they fit with the theme of dark matter.
I give a reference, this would only be a photon, let's take a normal light bulb, a light bulb that emits photons, a small light bulb, 10 W, something modest, imagine that it launched its photons, not as it normally launches them, but with that energy, well, it would be the same as throwing 30 billion ping pong balls at 100 km per hour, but per second, it would disintegrate you and your house in a second, we are talking about that energy concentrated in a single photon.
Where does that energy come from that has been detected in excess of what the calculations would be? astronomical and normal physicists according to this researcher, this excess of energy that cannot be explained by known astrophysical processes, turns out to coincide very well with the theoretical calculations of the predictions of the annihilation of dark matter particles, specifically the WIMPs, which are massive particles with a mass of around 500 times that of the proton.
If these particles exist and are dark matter, they should not interfere with anything, but of course, if they are concentrated, if they are in a concentrated area, they can rarely collide, but they can collide with each other and then if they collide they annihilate. Tomonori Totani stated that if confirmed it would be the first time that dark matter has been seen in the history of humanity, and it would also be the first indirect, strong evidence of the annihilation of dark matter particles.
