فوتونی که انیشتین را به چالش می کشد: طبق فیزیک فعلی، هرگز نباید به زمین می رسید

A photon that challenges Einstein: According to current physics, it should never have reached Earth

How did a photon survive a journey of more than 2 billion light-years when, according to known physics, it should have been absorbed long before reaching Earth? This is the question at the heart of a new study by Giorgio Galanti (INAF) and Marco Roncadelli (INFN), accepted for publication in Physical Review Letters.
