What no one has seen before: gravitational waveforms from warp drive collapse

Huh, so you <i>can</i> hear things explode in space, after all. If you&#x27;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&#x2F;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.

&gt; Our work highlights the importance of exploring strange new spacetimes, to (boldly) simulate what no one has seen before.<p>cute

Is this like imagining what jets would sound like and listening for that sound?

&gt; 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&#x2F;[R]<p>Interesting...<p>&gt; 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:&#x2F;&#x2F;www.ligo.org&#x2F;science&#x2F;GW-Burst.php" rel="nofollow">https:&#x2F;&#x2F;www.ligo.org&#x2F;science&#x2F;GW-Burst.php</a>

Does that means if we can make our gravitational detectors sensitive enough we can detect warp drives passing through the universe?

Are there any good resources for someone to learn how to write some Numerical Relativity code?

Still waiting for the complete lack of gravitational waves as result of Omega particles

Good thing it runs on negative energy - there&#x27;s no shortage of bad vibes in the world today!
