Not science, survival.

If they can somehow find a planet that can keep life, a "second Remnant", they could transport at least some of their civilians there to colonize it. Away from the Grimm, though there's also the question of what dangers could be in that world.

That way, they have least can retreat somewhere and start again if hell comes. Of course, this is without putting into the equation the resources and time needed.
