Black holes and entropy
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 increaseExpand

Does the missing mass problem signal the breakdown of Newtonian gravity
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 toExpand

Relativistic gravitation theory for the MOND paradigm
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 aExpand

Generalized second law of thermodynamics in black-hole physics
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 suggestedExpand

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

Spectroscopy of the quantum black hole
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 spacingExpand

Fine Structure Constant: Is It Really a Constant?
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 itsExpand
