If I'm not mistaken, even light cannot escape the gravitational pull of a black hole....

You are correct. if light can escape then its not a black hole. The reason being is the escape velocity is much higher then what even light travels at!! Black holes have tremendous amounts of mass in an incredibly small area of space. For example, if the earth became a black hole, with our current mass then we would have to shrink our planet to a sphere of about 9mm!!! There are reasons why its theorized that black holes could allow you to travel through time---> if you could pass through it without being torn apart at its singularity. Time dilation is cool.
