| contents | The recent detection by LHAASO up to 18 TeV of the gamma ray burst GRB 221009A at redshift $z = 0.151$ challenges standard physics because of the strong absorption due to the extragalactic background light (EBL) for photons with energies above 10 TeV. Emission models partially avoiding EBL absorption proposed to explain such an event are unsatisfactory since they require peculiar and contrived assumptions. By introducing in magnetized media the interaction of photons with axion-like particles (ALPs) - which are a generic prediction of most theories extending the standard model of particle physics towards a more satisfying theory - the detection of GRB 221009A can be naturally explained, thereby providing a strong hint at ALP existence. |
