In astrophysics, spaghetti fikation is the vertical stretching and horizontal compression of objects in long, thin shapes in a very strong gravitational field and is caused by extreme tidal forces. In the most extreme cases, near black holes, the stress is so strong that no object can resist it, regardless of the strength of its components. In a small area, horizontal compression compensates for vertical deformation, so that small objects that are pagetified do not experience a net volume change. In his book A Brief History of Time, Stephen Hawking describes the flight of a fictional astronaut stretched « like spaghetti » by the gravitational gradient from head to toe in the event horizon of a black hole. However, the term « spaghettification » was established long before; Nigel Calder, for example, uses it in his book The Key to the Universe: A Report on the New Physics, a companion to a unique BBC television documentary: The Key to the Universe. « You don`t hear about a lot of negative reactions on meatballs. But many Italians see spaghettification Bolognese, especially as a terrible injustice. Their attempts to correct it ranged from organized, high-level efforts to a kind of trench warfare of comments on the Internet. In 1982, the Bologna Chamber of Commerce officially certified what it considered an authentic recipe, which includes a beef skirt, pancetta, celery, carrots, onions, a little tomato, wine and milk. In astrophysics, spaghetti fikation (sometimes called the noodle effect)[1] is the vertical stretching and horizontal compression of objects in long, thin shapes (similar to spaghetti) in a very strong and inhomogeneous gravitational field. It is caused by extreme tidal forces.
In the most extreme cases, near a black hole, the stress and compression are so strong that no object can resist it. In a small area, horizontal compression compensates for vertical deformation, so that a small object in the process of spaghetti does not undergo a change in net volume. Whether this means they will actually correct us or Hollywood science is unclear, but I`m pretty confident that if they were made aware of the term spaghetti fikation and what it implies, they might want to use real science. Matter approaching the event horizon of a small black hole goes through a process called spaghettifikation, a term coined by Stephen Hawking in his book « A Brief History of Time » to describe exceptionally strong tidal forces. Stephen Hawking described the flight of a fictional astronaut who, in the event horizon of a black hole, is « stretched like spaghetti » by the gravitational gradient (difference in gravitational force) from head to toe. [2] The reason for this would be that the gravity exerted by the singularity would be much stronger at one end of the body than at the other. If one first fell into a black hole, the gravity at his feet would be much stronger than at his head, which would result in the vertical stretching of the person. In addition, the right side of the body is pulled to the left, and the left side of the body is pulled to the right, which compresses the person horizontally.
[3] However, the term « spaghettification » was established long before. [4] The spaghettification of a star was first photographed in 2018 by researchers observing a pair of colliding galaxies about 150 million light-years from Earth. [5] The spaghetti fikation theory will cause heat because you`re obviously breaking the molecular bonds that release energy. Unfortunately, everyone knows that there is a singularity lurking inside the black hole, and your fate will be spaghettification or worse. In this example, there are four separate objects in space above a planet positioned in a diamond formation. The four objects follow the lines of the gravitoelectric field,[6] directed towards the center of the celestial body. According to the law of the inverted square, the lowest of the four objects undergoes the greatest acceleration of gravity, so that all the formation extends in line. Stretching objects in long, thin shapes in a very strong gravitational field such as a black hole. In the previous case, the objects would actually be destroyed and people would be killed by heat, not by tidal forces – but near a black hole (assuming there was no matter nearby), the objects would actually be destroyed, and humans would be killed by tidal forces because there is no radiation. In addition, a black hole has no surface to stop a fall. Thus, the falling object is stretched into a thin strip of matter. Since when have we left the responsibility for black holes to the Italians?

Due to the high density, the tidal force near the surface of a white dwarf is much stronger, which, in the example, causes a maximum pulling force of up to 0.24 N. Near a neutron star, the tidal forces are again much stronger: if the rod has a tensile strength of 10,000 N and falls perpendicular to a neutron star of 2.1 solar masses, outside of fusion, it would break at a distance of 190 km from the center, well above the surface (a neutron star usually has a radius of only about 12 km). [Note 1] The process by which an object is stretched and torn by gravitational forces when it falls into a black hole These four objects are interconnected parts of a larger object. A rigid body resists distortion, and internal elastic forces develop as the body deforms to balance the tidal forces, thus achieving mechanical equilibrium. If the tidal forces are too great, the body can give way and flow plastically before the tidal forces can be balanced or break, creating either a filament or a vertical line of broken pieces. In the gravity field due to a point mass or a spherical mass, for a uniform rod aligned in the direction of gravity, the tensile force at the center is found by integrating the tidal force from the center to one of the ends. This gives F = μ l m/4r3, where μ is the standard gravity parameter of the massive body, l is the length of the rod, m is the mass of the rod and r is the distance to the massive body. For uneven objects, the pulling force is lower when there is more mass near the center, and up to twice as large when there is more mass at the ends. In addition, there is a horizontal compressive force towards the center. For massive bodies with a surface, the tensile force near the surface is the largest, and this maximum value depends only on the object and the average density of the massive body (as long as the object is small compared to the massive body).
For example, due to the tidal force, this maximum pulling force is only 0.4 μN for a rod with a mass of 1 kg and a length of 1 m and a massive body with the average density of the Earth. The point at which tidal forces destroy an object or kill a person depends on the size of the black hole. For a supermassive black hole like the one found at the center of a galaxy, this point is in the event horizon, allowing an astronaut to cross the event horizon without noticing pressure and traction, although this remains only a matter of time as it is inevitable to fall into an event horizon. [8] In the case of small black holes whose Schwarzschild radius is much closer to the singularity, the tidal forces would kill even before the astronaut reached the event horizon. [9] [10] For example, in a black hole of 10 solar masses[Note 2], the aforementioned rod breaks at a distance of 320 km, far from the Schwarzschild radius of 30 km. For a supermassive black hole of 10,000 solar masses, it will break at a distance of 3,200 km, far within the Schwarzschild radius of 30,000 km.
