Multiple independent astronomical studies confirm that gravitational lensing can bend the light of a distant supernova around a foreground massive object, creating multiple observable images of the same event at different times.
The claim states that gravitational lensing can allow the same distant supernova to be observed multiple times. Multiple retrieved papers discuss strongly gravitationally lensed supernovae (glSNe), multiply imaged supernovae, and the time delays between these multiple observed images. Therefore, the claim is fully supported by the literature.
