New research has suggested that nuclear pulps found in neutron stars may be the hardest material in the universe, and that to break it, it would take 10 billion times the force needed to break the steel.
As Charles Horowitz of Indiana University Bloomington explained, "It's a crazy number, but the material is also very, very dense, which makes it stronger." ScienceNews According to reports, the name "nuclear pulp" may suggest a material that is quite easy to break, but in reality, nuclear pulps are extremely robust and virtually impossible to break.
When dying stars explode, neutron stars rise up to take their place, and powerful gravitational forces beyond the measure create strong pressure on these objects. If you were to look only one kilometer inside one of these neutron stars, you would see atomic nuclei so closely linked that they turn into nuclear matter. These clusters of nuclear material, at least in theory, would look like objects such as sheets, tubes, and drops in general, and so have been named after their pasta counterparts like lasagna, spaghetti, and gnocchi.
If you were to travel further inside a neutron star, you would see nothing but nuclear matter, which would include all the core of this ancient star. The material called "nuclear pulp" is so dense that even the density of water is 100,000 trillion times lower than that of nuclear pulp.
As a result, nuclear pulps can never be experimented with and studied in the laboratory and can only be searched by computer simulations, which is used by researchers in the new pasta study.

Through computer simulation, researchers were able to take "lasagna sheets" and extend them, slowly extending them to see what happened to the material. To do this, enormous pressure was needed, and to break the pasta, it had to be so brutal that it was more difficult to break the simulation than any other material.
While earlier simulations of this type have shown that even the outer surface of neutron stars would be harder to break than steel, no research has been conducted so far on the inner regions of these neutron stars.
As the physicist Constança Providência noted, "researchers now see that the inner crust is even stronger."
The new study on the resistance of nuclear pulps in neutron stars has been published in Letters of physical examination.
