First of all, you need to prepare enough water and be equipped with a super strong pressure device.
When given a standard atmospheric pressure of 1,000, it is equivalent to the pressure of a 10,000-meter deep sea. Water under this pressure is still a liquid, but its density will be about 5% higher than the density of water we usually see.
When the pressure of 100,000 standard atmospheres is added to water, the hydrogen-oxygen bonds in the water molecules are broken, and it becomes a solid crystal. However, this crystal is not the ice we usually see, but a hydrogen atom. A polymer of and oxygen atoms.
When the pressure reaches 10 million standard atmospheres, water begins to exhibit a metallic state, forming metallic hydrogen . This is the energy substance that humans dream of. With it, you will become the richest man in the world in minutes.
When the pressure reaches 30 million atmospheres, you have to be careful. The pressure at this time creates an environment equivalent to that inside the sun. In this high-temperature and high-pressure environment, hydrogen atoms will start nuclear fusion , and nuclei will combine to form new substances. From hydrogen element to helium element , the new substance helium continues to be pressurized and fuses into carbon, and carbon fuses into oxygen. When you reach a pressure eight times greater than the pressure inside the Sun, you reach iron, the end product of nuclear fusion. In the process, a huge amount of energy is released, which is enough to destroy a city, so you must prepare a super container to imprison him.
If you don't stop at this point, the electrons of the iron atoms will try to compete with you. Once your pressure reaches one trillion trillion atmospheres, the atomic nucleus will be crushed, and the iron electrons will be completely defeated and combine with the positively charged protons to form neutrons. At this time, you will get Got a neutron star .
Do you know what a neutron star will look like if you continue to increase the pressure?
At this time, one cubic centimeter of matter weighs one billion tons, and the minimum mass of a neutron star is 1.44 times that of the sun. If you are not satisfied enough, when the neutron star exceeds the Oppenheimer limit through accretion, which is about 3.2 solar masses , the mass collapses infinitely, thus becoming a black hole as the pressure increases.
