Why I don't like the theory that if you travel through a black hole you'll reach another place...

This is an image from the movie star trek, where the space ship travels through a black hole into a parallel universe. While this would be really cool if that were true, this particular theory makes me rather skeptical.

If you were to go anywhere near a black hole, the gravity would pull you in to such a dense amount of space, there'd be no way to not be crushed under all that pressure....

even light can't survive it. How would a ship? Even one as big as this one!
