Hoping to find a wormhole is probably a waste of time, but trying to figure out how one would work and trying to create one on demand it pretty much the only viable way to travel anywhere in the universe. If that is not possible, then we're stuck here.
Our galaxy is what...100,000 light years across...so even if we travel at the maximum speed physics allows in a vaccuum...we're still not getting anywhere. We can't even visit out closest neighbor andromeda.
