Chapter 1: The Nature of Magnetars

Magnetars are remarkably compact celestial bodies characterized by their intense magnetic fields. Recent research suggests that these extraordinary objects might be cleaved in two by exceptionally powerful plasma blades, potentially explaining some of the most luminous explosions observed in the universe. A startling study indicates that relativistic blades—highly energetic plasma jets influenced by extreme magnetic forces—could be responsible for this phenomenon.

Section 1.1: Understanding Stellar Explosions

Moreover, the underlying causes of some of the universe's brightest bursts may be traced back to these star-splitting plasma blades. Researchers from New York University’s Center for Cosmology and Particle Physics shared their findings in a paper uploaded to the arXiv preprint repository in September. Notably, they discovered that the magnetic fields of magnetars can also channel powerful radiation beams along the star's equatorial plane. These beams, which release energy far exceeding that of a supernova, radiate outward at nearly light speed, shaped by the immense centrifugal forces generated by the star's rotation.

Subsection 1.1.1: The Mechanism of Stellar Disruption

The researchers revealed that these relativistic blades might effectively sever the star as they penetrate it. Following their exit, the blades can travel vast distances, significantly beyond the initial radius of the star, which may explain the prolonged duration of some gamma-ray bursts (GRBs). The fate of the star is inevitable; as the blade moves outward, it accrues additional material, contributing to its outward journey. This process instigates internal instability within the star, eventually culminating in its collapse.

Section 1.2: The Energy Requirements

To achieve such cosmic feats, immense quantities of energy and relativistic particles in plasma states would be necessary, along with methods to transport them to a star. Given that our Sun is the only nearby star readily accessible, it raises questions about the feasibility of such endeavors. If humanity were to attempt slicing a star in half, it could prove to be a calamitous decision in the long term.

Chapter 2: The Art of Cutting Stars

In the video "Make a Perfect Star with Just One Cut," viewers can learn about the fascinating geometry involved in star shapes and the precision needed to create them, drawing parallels to the cosmic phenomena discussed.

The second video, "How to Cut a Star with ONE CUT from a Square," provides a practical demonstration of cutting techniques that can be metaphorically related to the theoretical discussions of stellar dissection presented in this article.
