Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that gravitational lensing can allow the same distant supernova to be observed multiple times?

Yes. 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.

Verdict: SUPPORTED · 8 sources for, 0 against · Last checked

The analysis

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.
