I believe there is. Observed universe shines on us in a broad spectrum of electromagnetic and gravitational waves and particles, so knowing it well and expecting what may come from it is important, because we utilize more and more of this spectrum. If you build a neutrino detector, you are looking at the whole universe and trying to separate your own signal from the background. In space some strange recurring radio signal may interfere with satellite communications, you may need to distinguish it from something else. It’s all practical right now, even if we are not yet building machines to exploit some new physical law.
