Have gravitons been proved to exist?

    No. We know that if they did exist they would need to be massless spin 2 tensor bosons. However, no one has directly quantized gravitons into a finite theory. The problem seems to be the non-linearity of general relativity - gravitons beget gravitons which beget more gravitons .... and we get a non-converging theory. In any case, they would be almost impossible to detect considering how weak gravitational waves are.

      Hunter - if you know a simple way to describe the issues with a quantization of general relativity, have at it.

    Gravitons are theoretic particles and not proved yet but then most particles that have been proven to exist started out as theoretic!

    The Higgs bosun is a good example!

    Nor has gravitas, but it is taken seriously in the religious community as truth.

    No. Modern Physics has reached a point where a new Theory is needed. These tiny extremely sensitive and specific experiments are unlikely to find positive results outside of experimental error and analytic bias.

    They've been gravitating toward existing.

      just another particle which makes no physical mechanical sense
