Schwarzschild Radius and Event Horizon

Schwarzschild Radius and Event Horizon

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...

Gravitation Between Spherically Symmetric Masses

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.

Detection of Black Holes

Detection of Black Holes

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...

Reduced Mass Coordinates: Isolated Two-body Problem

Reduced Mass Coordinates: Isolated Two-body Problem

In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Newton's Law of Gravitational Attraction

Newton's Law of Gravitational Attraction

Sir Isaac Newton established the universality of the law of gravitational attraction based on empirical evidence and inductive reasoning. He published his work in Philosophiae Naturalis Principia Mathematica ("the Principia") on July 5, 1687.
Newton's law of gravitational attraction is a fundamental law of physics that governs the attraction between objects. It states that the magnitude of the gravitational force between any two objects is proportional to their masses and inversely...

Stability of Equilibrium Configuration

Stability of Equilibrium Configuration

Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

Summary

This summary is machine-generated.

Quantum gravity inspires exotic compact objects with surfaces near the event horizon. However, these objects are gravitationally unstable and collapse into black holes due to matter accretion, violating the Hoop conjecture.

Area of Science:

Theoretical physics
Quantum gravity
Astrophysics

Background:

Exotic compact objects with quantum gravity inspiration are theorized.
These objects possess physical surfaces near the black hole event horizon.

Purpose of the Study:

To investigate the gravitational stability of classical exotic compact objects.
To determine the conditions under which these objects avoid black hole collapse.

Main Methods:

Analysis of classical spacetime metrics for exotic compact objects.
Application of the Hoop conjecture to accretion processes.
Consideration of matter and gravitational wave accretion.

Main Results:

Classical exotic compact objects are shown to be gravitationally unstable.
Accretion of matter and gravitational waves drives collapse into a black hole.
The Hoop conjecture predicts collapse for these objects.

Conclusions:

Exotic compact objects require a macroscopic surface distance from the horizon or a violation of the null energy condition to remain stable.
These findings challenge the viability of certain quantum gravity inspired compact object models.
