The scientific method

karl PopperThe scientific method is a method of investigation used primarily in the production of knowledge in the sciences.

It is intended to be a pattern that allows researchers to go from the initial point of an investigation until conclusions with confidence to obtain valid knowledge.

The scientific method is supported by two pillars. The first of these is the reproducibility, i.e., the ability to repeat a given experiment, and the second pillar is the Falsifiability. In other words, that any scientific proposition must be capable of being falsifiable by experiments (Falsifiability). Karl Popper was who founded the epistemological current of the Falsifiability, refutationism or principle of falsifiability, by which to contrast a theory, should be able to try to refute it by a counterexample.

How a black hole is formed

Suppose a star like the sun that is exhausting its nuclear fuel turning its hydrogen into helium and this into carbon, oxygen and finally iron coming a time when the heat produced by nuclear reactions is short to produce a dilation of the Sun and thus compensate the force of gravity. Then the sun collapses increasing its density, being only slowed down this collapse by the repulsion between the electron shells of atoms. But if the mass of the sun is high enough it will be overcome this repulsion (exceeding the Chandrasekar limit) being able to get to merge the protons and electrons of the atoms, forming neutrons and reducing the volume of the star leaving no space between the nuclei of the atoms. The Sun was to become a sphere of neutrons and therefore would have a very high density. It would be what is called “neutron star”.
