That’s assuming they actually use a Star Trek style warp drive when we ALL know they are actually using Navigators to jump into the Immaterium.
Provided that’s even how they work
But what they hell do I know, I drive a forklift for a living not do science things with other science people at the science place
The whole thing is theoretical, but the more tools we have on our belt to look for intelligent life in the universe, the better.
That’s what it means to specialize.
You can detect a forklift before most other people can.
Of course it’s assuming that’s how advanced propulsion tech works. But it is useful to try to detect, just in case that’s how it actually turns out to work, no?
And if we detect something interesting, like a potential warp bubble collapse, well, that also gives us a strong hint that it’s possible, helping us to direct research in the right path.
Detecting techno-signatures of aliens would be super useful for us.
Scientists: We’ve been trying to reach you about your spaceship’s extended warranty…
you can’t see a failing warp drive through a cloak. duh.
Don’t forget to polarize the sensors.
