Huh, so you <i>can</i> hear things explode in space, after all. If you're close enough to a warp field doing funny things, the gravitational wave strain would create audible-frequency artifacts, as it wiggles your eardrums at frequencies close enough to the audible.<p>They derive an equation for estimated strain as a function of distance from the warp bubble collapse. How does strain translate to sound intensity, in the situation where a gravitational wave is driving sound pressure waves, and/or directly wiggling eardrums?
Funny that the sci-fi got it backwards.<p>It seems rather obvious in hindsight that should it even be possible, we will clearly be able to detect warp signatures far before we would be able to build a machine capable of producing them.
This is excellent. Like the Dyson sphere, predicting signals for technologies that we can imagine but not yet construct seems like a great way to guide our search for other life.<p>Now we need a team of smart folks to identify tearing or other processing anomalies in universe-scale simulations.
> The signal comes as a <i>burst</i>, initially having no gravitational wave content, followed by an oscillatory period with a characteristic frequency of order 1/[R]<p>Interesting...<p>> As discussed above, for a 1km-sized ship, the frequency of the signal is much higher than the range probed by existing detectors, and so current observations cannot constrain the occurrence of such events<p>And yet, you still chose the word ;)<p>So, how big are the ships, as a kindness for readers such as myself for whom the exercise should not be left?<p><a href="https://www.ligo.org/science/GW-Burst.php" rel="nofollow">https://www.ligo.org/science/GW-Burst.php</a>
