Black holes and entropy

- J. Bekenstein
- Physics
- 15 April 1973

There are a number of similarities between black-hole physics and thermodynamics. Most striking is the similarity in the behaviors of black-hole area and of entropy: Both quantities tend to increase… Expand

Does the missing mass problem signal the breakdown of Newtonian gravity

- J. Bekenstein, M. Milgrom
- Physics
- 1 November 1984

We consider a nonrelativistic potential theory for gravity which differs from the Newtonian theory. The theory is built on the basic assumptions of the modified dynamics, which were shown earlier to… Expand

Relativistic gravitation theory for the MOND paradigm

- J. Bekenstein
- Physics
- 30 March 2004

The modified newtonian dynamics (MOND) paradigm of Milgrom can boast of a number of successful predictions regarding galactic dynamics; these are made without the assumption that dark matter plays a… Expand

Generalized second law of thermodynamics in black-hole physics

- J. Bekenstein
- Physics
- 15 June 1974

In previous work we introduced the concept of black-hole entropy, which we identified with the surface area of the black hole in question expressed in units of the Planck length squared. We suggested… Expand

Universal upper bound on the entropy-to-energy ratio for bounded systems

- J. Bekenstein
- Physics
- 15 January 1981

We present evidence for the existence of a universal upper bound of magnitude $\frac{2\ensuremath{\pi}R}{\ensuremath{\hbar}c}$ to the entropy-to-energy ratio $\frac{S}{E}$ of an arbitrary system of… Expand

Spectroscopy of the quantum black hole

- J. Bekenstein, V. Mukhanov
- Physics
- 10 May 1995

Abstract We develop the idea that, in quantum gravity where the horizon fluctuates, a black hole should have a discrete mass spectrum with concomitant line emission. Simple arguments fix the spacing… Expand

Fine Structure Constant: Is It Really a Constant?

- J. Bekenstein
- Physics
- 15 March 1982

It is often claimed that the fine-structure "constant" $\ensuremath{\alpha}$ is shown to be strictly constant in time by a variety of astronomical and geophysical results. These constrain its… Expand
