Black Holes and "spaghettification"
Black holes, are stars with sufficient mass to collapse gravitational upon themselves once their cores have become unable to counter gravity via an outward thrust. Curiously, some physicists have delved and waxed melodic on whether black holes can be portals to other distant areas of our universe. They have also become quite popular in Sci Fi films in order to explain quick space travel over unimaginable distances. What they don't seem to want to explain is how the ship and its crew avoid spaggetification, a name which refers to the very nasty effect unequal gravitational forces exerted by the black hole has on objects that approache it. Below is a description of what exactly spaggetification involves.
In astrophysics, spaghettification (sometimes referred to as the noodle effect) is the vertical stretching and horizontal compression of objects into long thin shapes (rather like spaghetti) in a very strong non-homogeneous gravitational field; it is caused by extreme tidal forces. In the most extreme cases, near black holes, the stretching is so powerful that no object can withstand it, no matter how strong its components. Within a small region the horizontal compression balances the vertical stretching so that small objects being spaghettified experience no net change in volume.
Stephen Hawking described the flight of a fictional astronaut who, passing within a black hole's event horizon, is "stretched like spaghetti" by the gravitational gradient (difference in strength) from head to toe. The reason this happens would be that the gravity force exerted by the singularity would be much stronger at one end of the body than the other.
If one were to fall into a black hole feet first, the gravity at their feet would be much stronger than at their head, causing the person to be vertically stretched. Along with that, the right side of the body will be pulled to the left, and the left side of the body will be pulled to the right, horizontally compressing the person. However, the term "spaghettification" was established well before this. Spaghettification of a star was imaged for the first time in 2018 by researchers observing a pair of colliding galaxies approximately 150 million light-years from Earth.

So if indeed a black hole is ever to be explored via manned or unmanned probes, the problem of being stretched out like thin strand of spaghetti has to be definitely resolved. Otherwise, the so-called theoretical gateway will always lead to oblivion.
