The fast radio burst (FRB) is one of the most mysterious phenomena in the universe. The thing, that makes that radio burst mysteriously is that they seems to come outside our galaxy. And the other thing is that they might seem to have nothing, where they can come. The mystery is: why FRBs cannot form in our galaxy? The FRB is a similar phenomenon with gamma- and X-ray bursts.
The radiation frequency is different from that in GRB and XRB, and the problem is that those effects seem to have a source. The FRB is separated from the GRB and XRB which might form when neutron stars or black holes collide. The FRB is sometimes unique, and those three phenomena are not connected. So, the FRB doesn't mean that at the same time comes XRB and GRB. Those things come separately. And that makes them interesting.
In some models, there is the suggestion that the Doppler effect can be behind the FRBs. Or, otherways saying, the Doppler effect can have a connection with FRBs.
In the universe, high-power gravity fields like black holes can stretch wave movement. That means if the black hole is behind the gravity waves its gravity field can stretch gravity waves. And that effect means that the gravity wave's wavelength changes.
Theoretically is also possible that the gravity waves travel past lots of neutron stars and those things can change their wavelength. In the same way when the gamma rays impact with other gamma rays that can affect those high-energy waves' wavelength.
Normally doppler effect or redshift means a situation where wave movement stretches when an object's distance from the observer increases. The opposite effect, blueshift means that the wave movement's wavelength turns shorter when an object comes to the observer. When the object travels to the observer it gathers the quantum fields.
And that forms the wave, just like for example stones form when they hit water. So the thing, that differs this pressure effect from blue and redshifts is the wavelength and the size of the interacting particles.
When some high-energy particle comes from the intergalactic environment to the galaxy's halo it interacts the same way as particles, that come to the atmosphere. Those particles release their energy as radiation shockwaves. When some other energy impulse hits those shockwaves, that thing gathers or stretches the wave movement.
When extremely high-energy particles like Higgs bosons release their energy, that energy impulse forms a small void. And if some wave movement travels through that void, its wavelength changes. Same way, galaxies and black holes send radiation. When two radiation beams. With identical wavelengths hitting each other that affects their wavelength. And when wave energy impulse travels through the galactic plasma, that plasma pumps energy in it.
That means it's possible that the FRB forms when some other high-energy bursts impact each other. And that can change other radiation types into radio waves. Theoretically is possible that the gravity waves can turn to some other type of radiation or wave movement when they stretch or gather. And that thing makes it possible that the gravity waves can turn into gamma rays or even visible light.
