#2Funny that the sci-fi got it backwards.
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.

It's fun that people can get paid to do this.

#6This 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.
Now we need a team of smart folks to identify tearing or other processing anomalies in universe-scale simulations.

True, although the Fermi Paradox still sort of applies here, e.g., even if the galaxy were teeming with aliens zipping all over the galaxy in their warp-capable spacecraft, the odds of them charting a course right past our fairly uninteresting solar system seem low.
This is likely not helped by the fact that we are more than halfway out to the edge of the galaxy, in one of the Milky Way's spiral arms; since we're not near the galactic centre, there are less possible travel paths that pass by us (if we just assume arbitrary random travel between any two points.)
So even if it is happening right now in abundance, and even if we can detect its occurrence, are any of those paths close enough to us to be detected?

If you like spooky stuff there is lots of fun things to think about.
Just off the cuff; We are predicting a soul upload technology with Neuralink etc. So an alien technosignature could look like: https://en.wikipedia.org/wiki/21_grams_experiment
This one is not rigorous but there are lots of other possibilities of this pattern.

Advanced life. There is no particular reason to think there is life out there (if there is or not - both are extraordinary). If there is, there is no particular reason it is advanced - vs just some plants and animals living a life but not doing anything different from the first members of the species. (that is not advancing to where they might get a house)

#10Huh, so you can 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.
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?
