An international team of researchers from mcgill university california institute of technology and indiana university has calculated the strength of nuclear pasta extremely dense material deep. Understanding the strength of nuclear pasta will help astronomers studying neutron stars to better understand their physical properties allowing them to test out theories and models. The strength of the neutron star crust especially the bottom of the crust is relevant to a large number of astrophysics problems but isn t well understood said matthew caplan a postdoctoral research fellow at mcgill university in a statement.
Understanding how this nuclear pasta works is a key concern for our lasagna loving scientists. We find very strong breaking strain that can pin strong twisted magne c fields and help explain huge energy. Strongest material in the universe impact computa ons of the shear modulus determine frequency of neutron star crust oscilla ons.
Smart news keeping you current the universe s strongest material is a cosmic lasagna a new study suggests that the nuclear pasta found in neutron stars is 10 billion times stronger than steel. A team of scientists has calculated the strength of the material deep inside. September 18 2018 source.
Nuclear pasta the hardest known substance in the universe date. Additionally the researchers wrote in their paper the large strength and density of nuclear pasta predicted by this work suggests that neutron stars may support large buried mountains in the inner crust what this means is that because of these dense regions the neutron star s interior could be lumpy and uneven. Physical review letters a team of scientists has calculated the strength of material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
Different pasta like shapes in which nuclear matter at various layers of a neutron star from the crust to the core aggregate. Between the surface of a neutron star and the quark gluon plasma at the core at matter densities of 10 14 g cm 3 nuclear attraction and coulomb. In astrophysics and nuclear physics nuclear pasta is a theoretical type of degenerate matter that is postulated to exist within the crusts of neutron stars if it does in fact exist nuclear pasta is the strongest material in the universe.
Nuclear pasta is thought to exist only inside neutron stars which form when massive stars at least eight times the mass of earth s. Much of nuclear pasta s strength likely comes from its density.
