Neutron Stars: The ‘Death’ of a Death Star

Introduction: Neutron stars are dense, compact masses of subatomic particles (called ‘fermions’) compressed by great gravitational forces (Reisenegger 1). They are classified into three groups: the radio pulsars, which are rotating neutron stars that are predictable pulsators of radio waves due to its fast (Landau n. p.; Reisenegger 2) although sometimes slow (Fuller, et al. 1) rotation; magnetars, which neutron stars with the strongest magnetic fields in the universe and violently burst high-energy X-ray and gamma rays (Landau n. p.); nonrotating binary neutron stars, which are emitters of x-rays (Reisenegger 3); and PSR ...

Introduction

The very title of this article may seem to some readers fantastic. Is there any evidence that alien beings exist? Can we prove that there is no clear scientific argument in favor of their life and activity? Such questions immediately arise among readers, of course, they are quite natural. And yet, I will try to show that the statement of the problem in our time of exclusively rapid scientific and technical progress is quite logic. Moreover, most recently the first steps towards the solution of this great problem facing mankind were taken. Basically, from the scientific point of view ...

Introduction

Our galaxy, the star system of our solar system, is called the Milky Way. The Milky Way is a grand cluster of stars visible in the sky as a bright band of fog. In the ancient Greek, the word "galaktikos" means "milk", "milky", so the Milky Way and stellar systems similar to it are called galaxies. In our galaxy, there are more than 200 billion stars of very different luminosity and color ("The Milky Way Galaxy - 200 billion stars", 2016). The Solar neighborhood is the volume of the galaxy, where we can observe and study the stars of ...

Black holes are space zones in the universe that are dark in nature and possess natural forces of attraction that have a very high gravity. This implies that they are able to attract and pull anything including light at a very high speed. This explains the origin of the name, Black hole. Several myths have been generated in many attempts to try and explain what a black hole is and Hollywood is at the forefront of it. Movies from Hollywood portray black holes as time physical entrances to tunnels that if one goes through, he can either move back or fourth in ...

For far too long, humanity has been content with unquestioned faith in subjective knowledge passed down from generation to generation. This has been especially true on issues regarding the origins of our species and, indeed, the universe. However, in the last 100 years, a new culture has emerged. A culture rooted in the ideals espoused by such trailblazers as Bertrand Russell; a belief in scientific understanding of the world we live in and veneration of acquisition of knowledge. The human race is no longer content with fables and fairy tales. We want to know how, when and why our universe came ...
