Gravity and its Mysteries: Some Thoughts and Speculations
A. Zee
I gave a rambling talk about gravity and its many mysteries at Chen-Ning Yang's 85th Birthday Celebration held in November 2007. I don't have any answers.
Does string theory predict an open universe?
R. Buniy, S. Hsu, A. Zee
It has been claimed that the string landscape predicts an open universe, with negative curvature. The prediction is a consequence of a large number of metastable string vacua, and…
Discreteness and the origin of probability in quantum mechanics
Roman V. Buniy, Stephen D. H. Hsu, A. Zee
Attempts to derive the Born rule, either in the Many Worlds or Copenhagen interpretation, are unsatisfactory for systems with only a finite number of degrees of freedom. In the cas…
Is Hilbert space discrete?
R. Buniy, S. Hsu, A. Zee
We show that discretization of spacetime naturally suggests discretization of Hilbert space itself. Specifically, in a universe with a minimal length (for example, due to quantum g…
A speculative relation between the cosmological constant and the Planck mass
S. Hsu, A. Zee
We propose the relation where , and denote the mass scale associated with the cosmological constant, the gravitational interaction…
The Graviton and the Nature of Dark Energy
A. Zee
I discuss various thoughts, old and new, about the cosmological constant (or dark energy) paradox. In particular, I suggest the possibility that the cosmological ``constant'' may d…
