Find material 10 billion times harder than steel

The crust of the hidden crystals has 10 billion times the hardness of ordinary steel. This helps them create gravitational waves that we can detect from the earth.

Metaphors (neutron stars) are the core left after super-massive stars explode. They are extremely dense, with the same mass as the sun but approximately 20 km in diameter. Some hidden crystals rotate at a rate of hundreds of times a second and release much energy into the surrounding space. We do not see the crystal with the naked eye but only detect it via radio signals.

Due to the tremendous gravitational and rotational speed, crystal hides often produce a multitude of extremely strong gravitational waves. But they can only do that if their surface has protrusions (like a mountain range) or depression. These defects make the spherical object become asymmetric. When pulsars are no longer symmetrical, they emit gravitational waves. Due to the extremely large material density, the height of the mountain (or the depth of the valley) on the crystal hidden in cm.

Scientists think that protrusions can be created in a number of ways. For example, metaphors can 'swallow' material from a nearby star. The protrusions can also appear from high temperature areas on the surface of the crystal. In theory, high protrusions will last for a long time on the surface of the crystal.

'Their crust is made up of ultra-neutron-rich atoms. No one has ever been able to determine the resistance of the hidden shell. We want to know if it is hard enough to support the weight of a mountain, or it will collapse on its own mind , 'said Charles Horowitz, an Indiana University scientist.

Because experiments on the earth cannot create the same conditions as on the surface of the planet, astronomers believe that their shells have the same hardness as the most solid materials on Earth. However, Horowitz's simulation models show that the hull of the crystal is much harder.

Stones, steel and many other materials break because their crystals have gaps. In addition, some other defects also create cracks in the crystal structure. But super-large compression on the planet makes the gaps and cracks impossible to exist. That makes crystals almost impossible to break. A cubic meter of hidden shell can be laminated 20 times more than a cubic meter of stainless steel before breaking.

Because the atoms in the asteroid are much closer to each other than the atoms in iron, they only break when subjected to a compressive force 10 billion times that of iron. That terrible hardness helps the asteroid to withstand the masses of 'mountains' about 10 centimeters high and stretch for many kilometers.

Simulated models also shed light on the "earthquake" phenomenon on the surface of stars. This phenomenon occurs when extremely large electromagnetic fields tear the shell of a hidden crystal. The harder the subtle shell, the stronger gamma rays and gravitational waves the seismic forces make.
