>Unambiguous detection of individual gravitons, though not prohibited by any fundamental law, is impossible with any physically reasonable detector.[18] The reason is the extremely low cross section for the interaction of gravitons with matter. For example, a detector with the mass of Jupiter and 100% efficiency, placed in close orbit around a neutron star, would only be expected to observe one graviton every 10 years, even under the most favorable conditions.
What?
If the graviton really is the carrier of the gravitational force, than any body experiencing gravity must be expressible in terms of that body interacting with gravitons. If the detector is in orbit, then it must be experiencing the neutron star's gravity, therefore it must be interacting with its gravitons, and substantially. In contrast, it barely interacts with neutrinos at all. Yet it only detects one graviton in ten years? Is this saying that a single, discrete graviton carries a tremendous "amount" of graviry?

Isn't there something similar with neutrinos. Something like a single neutrino could pass through a block of 1 ly long with only 50% chance of intetaction?

a block of *lead* 1 ly long

I though gravity was not a force, but a bending of space-time.
What are gravitons supposed to interact with ?

Gravity is a field. Always has been, always will be. Scientists will never find the graviton. You can't break gravity down into quanta.

how would gravitons and general relativity, which describes gravity as a position dependend metric, work together?

so is the electric field

protip : gravitons are a meme and don't actually exist.

>>9140723
Gravity is undetectable, like space/time itself.

Yes, but at least an absurd number of neutrinos streams through a square kilometer on Earth every second. How the hell do gravitons even work if they're apparently so rare?

Don't think of gravitons as the force-carriers of gravity. Gravity is a field, and gravitons, if they exist, are just perturbations in the field. Even under a relatively strong gravitational field, i.e. a neutron star, those perturbations are still not very common and not very energetic. It's just like how it took us forever to detect a Higgs boson, even though we were pretty damn sure the Higgs field was an actual thing.
