This event was recorded with energies of up to 18 TeV z=0.151, which indicates that it occurred approximately 1.5 billion light-years from Earth. The importance of this detection lies in the fact that, according to current models of the extragalactic background light (EBL), photons with energies greater than 10 TeV should be strongly absorbed before reaching our planet. EBL models, such as the one proposed by Saldana-Lopez et al., predict an extreme attenuation for high-energy photons. This implies that the observation of GRB 221009A requires an extremely high TeV luminosity, which is difficult to explain within conventional emission models. Thus, a dilemma arises: either the universe is more transparent than previously believed or we need to consider new physical phenomena. The proposed solution involves the interaction between photons and axion-like particles (ALPs), which are predicted by theories beyond the standard model, such as string theory. ALPs are very light and neutral particles that can oscillate into photons in the presence of magnetic fields. This interaction not only increases the probability of photons surviving, but also allows them to pass through the EBL without being absorbed. Thus, photon-ALP oscillations can occur in various magnetized media, such as the GRB host galaxy and in extragalactic space. The study suggests that photon-ALP interactions can occur efficiently in the GRB 221009A host galaxy, which was identified as an edge-on disk galaxy. Furthermore, the oscillations can also occur in the Milky Way and in extragalactic space, depending on the strength of the external magnetic field. The developed model provides a robust explanation for the detection of GRB 221009A without relying on ad hoc assumptions often required in conventional models. The results indicate strong evidence for the existence of ALPs, in line with other previous observations in blazars, which are active galactic nuclei. Spectral analysis of GRB 221009A shows that there is no significant cutoff in the spectrum up to about 20 TeV, allowing a safe extension of the emission up to this energy without intrinsic biases. In conclusion, the detection of GRB 221009A not only challenges existing theories about gamma rays and their interaction with the universe, but also suggests new directions for research on exotic particles such as ALPs. This event represents an important step in the understanding of fundamental physics and in the search for answers about the nature of dark matter, reinforcing the need for revisions in current theories of astrophysics.
