An even better one would be "Einstein's General Relativity model supported by (another) observation". We've had many similar observations already (e.g. Mercury's procession around the Sun) that provide similar confirmation.

That's why there is such consternation about it, versus the Standard Model born of quantum physics: both models have tons of confirming evidence supporting them, and yet they are at some level incompatible/incomplete. There's a gap in our knowledge, understanding, and intuition.

Publication bias might suggest otherwise.
