Detection of Black Holes01:10

Detection of Black Holes

2.3K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Schwarzschild Radius and Event Horizon

2.1K
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...

Toroids01:27

Toroids

3.0K
A toroid is a closely wound donut-shaped coil constructed using a single  conducting wire. In general, it is assumed that a toriod consists of  multiple circular loops perpendicular to its axis.
When connected to a supply, the magnetic field generated in the toroid has field lines circular and concentric to its axis. Conventionally, the direction of this magnetic field is expressed using the right-hand rule. If the fingers of the right hand curl in the current direction, the thumb...

Symmetry in Maxwell's Equations

3.5K
Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

Gravitation Between Spherically Symmetric Masses

The gravitational potential energy between two spherically symmetric bodies can be calculated from the masses and the distance between the bodies, assuming that the center of mass is concentrated at the respective centers of the bodies.

Summary

Black holes possess a vortex structure, explaining their stability and potentially powering active galactic nuclei jets. This discovery offers new insights into dark matter and hidden sectors.

Area of Science:

  • Theoretical Physics
  • Astrophysics
  • Quantum Gravity

Background:

  • Black holes are typically described by general relativity, with their stability against Hawking radiation being a key theoretical challenge.
  • The concept of 'saturons' representing objects with maximal entropy compatible with unitarity has emerged as a potential link between quantum mechanics and gravity.
  • Active galactic nuclei (AGN) jets are powerful outflows, but their precise mechanisms, especially in the absence of a magnetized accretion disk, remain incompletely understood.

Purpose of the Study:

  • To propose and investigate a vortex structure within black holes based on graviton-condensate and saturon descriptions.
  • To explore the implications of this vortex structure for black hole properties, including spin, stability, and observable phenomena like AGN jets.
  • To examine the potential of black hole vortex dynamics to probe hidden sectors, such as dark matter.

Main Methods:

  • Describing black holes as graviton condensates with emergent vortex properties.
  • Establishing a correspondence between black holes and Q-ball-type saturons within a renormalizable theory.
  • Analyzing the spin extremality bounds and magnetic flux trapping within the proposed vortex model.

Main Results:

  • A vortex structure in black holes, arising from a graviton condensate, explains their extremal spin and topological stability against Hawking evaporation.
  • A Q-ball-type saturon with vorticity obeys the same extremality bound on spin as a black hole.
  • The black hole vortex can trap magnetic flux, potentially explaining powerful AGN jets even without a magnetized accretion disk and offering a window into millicharged dark matter.

Conclusions:

  • Black holes exhibit a vortex structure, providing a topological explanation for the stability of extremal black holes.
  • The vortex mechanism offers a novel explanation for AGN jets and suggests a new avenue for detecting hidden sectors like millicharged dark matter.
  • This research bridges concepts from quantum gravity, condensed matter physics, and high-energy astrophysics, revealing interconnected phenomena.
