When a human enters free-fall, such as this 1960 skydive jump by Colonel Joseph Kittinger from over 100,000 feet, they a

That “rising stomach” sensation that you’d feel — like you get at the top of a drop on a roller coaster — would begin as soon as free-fall started, but would continue unabated.

At every point along an object attracted by a single point mass, the force of gravity (Fg) is different. The average force, for the point at the center, defines how the object accelerates, meaning that the entire object accelerates as though it were subject to the same overall force. If we subtract that force out (Fr) from every point, the red arrows showcase the tidal forces experienced at various points along the object. These forces, if they get large enough, can distort and even tear individual objects apart. (VITOLD MURATOV / CC-BY-S.A.-3.0)

By the time you’re 99% of the way to Earth’s center, the force pulling your feet away from your torso and your head away from your feet works out to about 110 pounds, as though the equivalent of nearly your own body weight was working to pull you apart.

Both inside and outside the event horizon of a Schwarzschild (non-rotating) black hole, space flows like either a moving walkway or a waterfall, depending on how you want to visualize it. At the event horizon, even if you ran (or swam) at the speed of light, there would be no overcoming the flow of spacetime, which drags you into the singularity at the center. Outside the event horizon, though, other forces (like electromagnetism) can frequently overcome the pull of gravity, causing even infalling matter to escape.

Here on the surface of Earth, these tidal forces on a human being are minuscule: a little less than a millinewton, or the gravitational force on a typical small earring. But as you get closer and closer to Earth’s center, these forces octuple each time you halve your distance.

If you were represented by a sphere falling towards a central point mass, like a black hole, these arrows would represent the tidal forces on you. While, overall, you (as the falling object) would experience an average force over your entire body, these tidal forces would stretch you along the direction towards the black hole and compress you in the perpendicular direction.

For a sphere, like the Moon, the point closest to the mass will be attracted the most; the point farthest from it will be attracted the least; the points that are off-center will be preferentially attracted to the center. While the center itself experiences an average attraction, the points all around it will experience different levels, which stretches the object along the direction of attraction and compresses it along the perpendicular direction.

That’s because your body, as you fall closer and closer to the center of the collapsing Earth, starts to experience enormous increases in tidal forces. While we normally associate tides with the Moon, the same physics is at play. Every point along any body in a gravitational field will experience a gravitational force whose direction and magnitude are determined by their displacement from the mass they’re attracted to.

When you experience a force on your body that’s equivalent to the gravitational acceleration on Earth — or a force that’s equal to your weight — scientifically that’s known as “1g” (pronounced “one-gee”). Typically, humans can only withstand a handful of gs over a sustained period of time before either lasting damage occurs or we lose consciousness.

This illustration of spaghettification shows how a human gets stretched and compressed into a spaghetti-like structure as they approach the event horizon of a black hole. Death by these tidal forces would be painful and traumatic, but at least it would also be quick. (NASA / PUBLIC DOMAIN / COSMOCURIO OF WIKIMEDIA COMMONS)

related issue, it’s unquestionable that “defund the police” and/or “end policing as we know it” are slogans that have a sizable following among Democrats. (Although “defund” doesn’t mean “abolish,” using eliminationist language to refer to issues of safety and policing is just terrible branding.) In June, a majority of the Minneapolis City Council actually adopted a pledge to dismantle the police force and replace it with a new system of “public safety.” (Now, some council members are backing away from it and saying that “dismantle” is up for interpretation.) Abolition or even significant reduction of policing, by the way, is not a popular stance with the black community.

As you can see from the illustration above, the size of the arrows — as well as the speed that they move at — increases as we get closer to the central singularity of a black hole. In Newtonian gravity, which is a good approximation as long as you’re very far away from the event horizon (or the equivalent size of the event horizon), the gravitational acceleration you experience will quadruple every time your distance to a point halves. In Einsteinian gravity, which matters as you get close to the event horizon, your acceleration will increase even more significantly than that.

Let’s take interviewing as an example. Besides showing up prepared (i.e., with a printed portfolio), one way you can demonstrate this in an interview is to ask the interviewer if there’s anything you can provide to them to help him/her make a decision. Let them give you a task that you can take home and work on. This will show them that you’re willing to invest the time, energy, and effort to prove your proactiveness. It also gives you a reason to follow up, which, in itself, is proactive. Figure out how to bring value, and you’ll stick out among the other candidates.

By the time you’ve reached about 25 kilometers from the central singularity, you’ll cross a critical threshold: one where these tidal forces will cause traumatic stretching your spine, causing it to lengthen so severely that the individual vertebrae can no longer remain intact. A little farther — about 14 kilometers away — and your joints will begin to come out of your sockets, similar to what happens, anatomically, if you were drawn-and-quartered.

Which is a good thing, because not only would you fall faster and faster towards the Earth’s center as time went on, but your acceleration would actually increase as you got closer to that central singularity.
