is not going to have a universal relation between the boat passed and then it moved.

But okay, so imagine, let's do the buoy analogy.

So I don't think the math works out the same, but imagine you have like some boat passing and you knew that like you could infer like the amount of like munitions on this boat because like the buoys moved a certain amount.

No,

Like, you know what I mean?

Like, some net property of, like, the thing.

So it's not as cool as that because I think that in that situation, it's not a universal relation between the things that scattered had some kinematics that then set the value of this shift.

But, yes, you have these two gravitational, like...

wave detectors, some probes sitting very far away, just minding their own business.

They're sitting along geodesics.

This wave passes and then the distance between them is going to change.

And like, depending on where they were relative to this thing, there's a certain like pattern in the sky that it would.

And you're seeing that there's a relationship between this distance changing and like the kind of net kinematics of the amount of like energy in the things that were scattering and the waves coming out.

And so there's this relationship that's like conservation of energy generalized to this kind of fun asymptotic symmetry version of it turns into

And move a little bit.

So that would be kind of an analogy for maybe the gravitational potential kind of curving you in.

I think this is closer to the buoy analog.

The math is wrong.

This isn't true for this case, I'm pretty sure.

of like imagine that you could have some buoys pretty far away and you knew that there was always a shipping route where they go like from here to there and like the only options are like the direction in which they came and like maybe the like the momentum of that boat and you could infer from the buoy shift those types of quantities regardless of whatever they did in the middle so that's not going to be true for the the water wave this i'm pretty sure it's not true for the deep water wave case but for the uh this gravitational system there's a symmetry reason why
