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 proportional...

Newton's Law of Gravitation

Newton's Law of Gravitation

Our everyday observation tells us that all objects close to the Earth naturally tend to fall to the ground. Early philosophers assumed that this downward force was unique to Earth. By the 16th century, Nicolaus Copernicus (1473-1543) put forward the heliocentric theory, which suggested that Earth and other planets orbited the sun, while the Moon orbited the Earth. However, it was Isaac Newton (1642-1727) who linked these two motions together in the 17th century. He reasoned that the force of...

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.

Potential Energy due to Gravitation

Potential Energy due to Gravitation

Since gravitational force is a conservative force, the amount of work done to move an object between two points in the gravitational field in which it resides is independent of the path taken. Thus, similar to the gravitational field, a gravitational potential energy function can be defined, which depends only on spatial coordinates.
Consider a mass gravitationally bound to another object. For example, the Earth is gravitationally bound to the Sun’s gravitational field. The potential energy of...

Gravitational Potential Energy for Extended Objects

Gravitational Potential Energy for Extended Objects

Consider a system comprising several point masses. The coordinates of the center of mass for this system can be expressed as the summation of the product of each mass and its position vector divided by the total mass:

Gravity between Spherical Bodies

Gravity between Spherical Bodies

Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...

Summary

This summary is machine-generated.

The Dirac-Born-Infeld extension of new massive gravity naturally arises as a counterterm in anti-de Sitter space. This counterterm yields cutoff-independent results for black hole entropy and relates to a c=0 theory in AdS/CFT duality.

Background:

The study of massive gravity theories is crucial for understanding gravitational phenomena.
Anti-de Sitter space (AdS) and its holographic duals provide a framework for quantum gravity.
The Dirac-Born-Infeld (DBI) action is a key concept in string theory.

Purpose of the Study:

To investigate the emergence of the DBI extension of new massive gravity in AdS(4).
To analyze the properties of the on-shell Euclidean action and black hole entropy.
To explore connections with AdS/CFT duality and Chern-Simons theory.

Main Methods:

Identifying the DBI extension as a counterterm in AdS(4).
Calculating the on-shell Euclidean action and its cutoff independence.
Deriving the AdS(4) Schwarzschild black hole entropy using the counterterm.
Analyzing the parameter values in relation to a c=0 theory and AdS(3)/CFT(2) duality.

Main Results:

The DBI extension of new massive gravity naturally emerges as a counterterm in AdS(4).
The on-shell Euclidean action is cutoff-independent at zero temperature.
The counterterm leads to a cutoff-independent area law for AdS(4) Schwarzschild black hole entropy.
The parameter values correspond to a c=0 theory, linking to AdS(3)/CFT(2) duality.

Conclusions:

The DBI extension provides a consistent framework for studying gravity in AdS(4).
The findings offer insights into the holographic principle and quantum gravity in lower dimensions.
The study establishes a connection between massive gravity, AdS/CFT, and Chern-Simons theory.
