FRB:s and the mystery behind them
The thing, that is remarkable in FRB:s (Fast Radio Bursts) is why they are not happening in our galaxy? Why they are always happening in some distant galaxies? This is one of the most interesting questions, what astronomers may face in the 21st century. FRBs are really hard to observe because they are so fast.
And there are no predictive warnings about those signals. So the system what meters that kind of thing is really difficult. The thing that makes those radio signals, what are standing only 75 milliseconds special is that from those targets is not finding to come other radiation at all. And the thing, what makes that kind of thing very interesting is that normally black holes are causing the X-ray or gamma-ray bursts.
Is the FRB result for the collapse of the star, what is smaller than the sun, and have a certain chemical structure? In this hypothesis, the star would collapse to the white dwarf and sends very little gas to the universe during the reaction, and then the thing would cause the radio impulse because the explosion would send mostly the fast electrons or beta rays to the universe. That means that this phenomenon is like some kind of cosmic neutron bomb.
But there is one very interesting theory about that kind of radio bursts, and that is the radio burst is the final moment of some star, what just drops in its center because the production of the energy is ending. But is it possible that the core of the stars would just drop in the center, and there would be no other sign of that kind of catastrophe? When we are thinking about the end of the stars, what are the size of the Sun or smaller, they don't explode so imposingly than some Betelgeuze, and the result of the explosion is a white dwarf.
So is it possible that that thing, what forms the FRB is the smaller star than the Sun? When the nova eruption happens, there is a possibility that the last spasm of the star is causing the reaction, where the very little gas is releasing from the eruption and most of the radiation would release in the form of the radio impulse, because it would release the very large number of electrons during the collapse. This thing can explain, why the FRBs are so unusual. That means the FRB can be some kind of cosmic version of the neutron bomb.
As I wrote, in the beginning, the thing that all FRBs are happening at distant galaxies is very interesting. If we are thinking about this kind of thing carefully, FRBs should happen also in our galaxy. That thing would tell that there should be some kind of special chemical structure of the sources, what are sending that kind of thing. And maybe the new instruments are answering that mystery.
