Sources of Noise?!

Doesn't that mean that the gravitational field is an information storage and transmission medium; a signal channel?

Is it lossy?

Is there a routable signal path to block harassing calls?

Is it slower or cheaper than nonlocal entanglement; like quantum radar?

What is the minimum energy necessary to cause a propagating thresholdable-as-binary pertubation of a gravitational field?

I think you may be engaged in circular reasoning, here. Noise, by definition, is what can’t be modeled. The idea would be to have some model of the signal produced by the submarine’s machinery, and use that to reduce the noise (increase SNR) to the point that this nav system becomes useful.

Of course we would always filter out noise completely if it was that easy to model. My point was that some components of that noise (for example the moving parts of the engines) can be modeled very accurately.

I think we’re saying the same thing?

samus2y ago

Yes, indeed

Not a formal definition, but noise is simply the undesirable parts of the output of any information processing device, be it a sensor, an amplifier, or a transmission medium. But on Earth it's simply not practical as such. Gravitational waves observatories are used to detect events such as neutron star or black hole mergers that are otherwise unobservable, but they require an insane level of precision to be detected.

Are there yet any instruments better than LIGO at a lagrangian point outside Earth's atmosphere and the Van Allen radiation belt?

No, there’s nothing yet. I think you‘re thinking about (e)LISA btw.

It sure is a medium! One Denver (IIRC) gravitational experiment could measure the field distortion caused by 100,000 people and cars at a local sports arena. [citation needed]

Is there a butterfly effect -like minimum pertubation for gravitational wave propagation through matter or massful things, at least?

Is there something that's low-enough power to not EM-burn a brainstem in a crytographically-keyed medical device with key revocation?

Does a fishing lure bobber on the water produce gravitational waves as part of the n-body gravitational wave fluid field, and how separable are the source wave components with e.g. Quantum Fourier Transform/or and other methods?
