It can't be complete and all there is, because it doesn't explain everything we know exists. To simply quote wikipedia:
"It does not fully explain baryon asymmetry, incorporate the full theory of gravitation as described by general relativity, or account for the accelerating expansion of the Universe as possibly described by dark energy. The model does not contain any viable dark matter particle that possesses all of the required properties deduced from observational cosmology. It also does not incorporate neutrino oscillations and their non-zero masses."

However, it could very well be that a true scientific theory that explains those things is beyond our experimental verification, and the Standard Model (or something not much beyond it) will fit all particle accelerator observations made in the next thousand years or more.
- nine_k 7y agoFortunately we have astronomic events. No Earth-based experiment could emit gravitational waves strong enough to detect; good thing the Universe has plenty of black holes, and some of them merge.
- CharlesColeman 7y ago> Fortunately we have astronomic events. That may help with some things, though it's not at all clear it's sufficient to verify a true theory that "explain[s] everything we know exists." It brings to mind the graviton, which I've read would be practically impossible to detect: you could detect one graviton every ten years with a Jupiter-mass detector placed very close to a neutron star, but the shielding needed to exclude the noise would cause it to collapse into a black hole.
