The general laws of physics, sure, I have no solid reason to think they’ll be forever out of reach (only doubt), but in order to determine if there was intelligent life (even moreso civilizations) in galaxies that have already stranded away from our field of vision, we would need to have immense luck for physics to allow us to cheat the limits we know about today.
Again, we can’t even begin to speculate on what we’ll know in 1000 or 10,000 years because it’s so far beyond our current understanding. Practical time travel might be discovered. Or maybe we’ll learn how to extrapolate the path of any number of particles all the way back to the Big Bang and effectively learn all of the past.
