Worm holes are still theoritical atm unfortunatley. Would be a huge step to find one and start dropping probes into it, that's the day humanity changes forever. Black holes may lead to somewhere though, we can't find out yet. The gravity would crush any device we sent in and it would have to move faster than light to get data back out to us. The greastest thing about science is that it makes the impossible very possible so hold out hope i'd say!
