Theories of gravity that predict gravitons haven't failed or "succeeded" (whatever that might mean) since they are still hopeful candidates. – JamalS Aug 07 '20 at 10:04

i'm talking about infinities at small distances and such. I read them but couldn't make much sense. – user146021 Aug 07 '20 at 10:05

Which graviton theory are you referring too? – my2cts Aug 07 '20 at 10:35

A standard QFT for the Einstein action is non-renormalizable, which is problematic. There are other approaches to gravitons, such as string theory, which solves the issue of small-distance divergences by introducing a cutoff-scale: the length of the string.
