It is theorized that a physical object that falls into a black hole will, once inside, undergo what folks in the trade fancifully call "spaghettification".  Tidal forces stretch the thing out to such extremes that it ends up as only a stream of particles heading towards the singularity in the center. This can be thought of thusly - the gravitational force between two objects decreases as the distance between the objects increases.  This creates the ocean tides, as the pull of the Moon on the side of the Earth nearest it is greater than on the side farthest away.  The oceans are not solid, and deform into "tidal bulges" from this.In black holes, this effect becomes extreme.  If you fall in feet first, you'll reach a point where the downward pull on your feet is notably stronger than that on your head.  So, your feet get pulled towards the center more quickly, and you get stretched.  Eventually, it is enough to rip asunder any material you'd care to name.The gravitational redshift of light trying to leave the hole, or the area near the hole, is not a tidal force phenomenon.</blockquote>
