I can see that type of shift, like the buoys move by certain amount.

That means blah, like this amount of energy was deposited, like type of thing.

That's the whole point.

So this is supposedly like the, at the very end it stayed.

Now in practice, that's not super useful.

Cause we're like, we do these things where we have a theoretical framework where the math is rigorous and then it's completely BS in the sense of that's not the thing you're going to measure.

So like in my framework, I'm doing that single whatever.

ship crossing type of thing as the entire everything that happened in the whole world infinite amount of time but what you do then is you say okay there's this effect that this framework studies but it really is only accurate for like each individual scattering experiment is like a chunk and so there there's a shift from that scattering experiment and sure something else is going to move it around later but if they're spaced off enough in time can i approximate this thing as like the memory effect

Yeah, exactly.

Yeah, something else moves it.

And then there's a very formal version where we say, imagine you wait for an infinite amount of time, tell me the beginning and the end, and that's technically the memory effect.

But in practice, it's closer to like, let's pretend there was just one

thing that happened, one thing you're detecting, so one event.

And as far as those time cells are concerned, it's a lot longer than any other thing later moving it.

And so then that's a memory.

I discovered a variant of this based on the connection to these symmetries.

So this variant is like angular momentum loss instead of energy loss in the gravitational waves and the spinning particles kind of.

So basically it's like, and this was the kind of fun thing.

So I come into my PhD and you're almost just going to do like classical radiation.

So like, you know, you accelerate a charge, it's like emitting radiation.
