Cyclic Universe and Infinite Past
Paul H. Frampton
We address two questions about the past for infinitely cyclic cosmology. The first is whether it can contain an infinite length null geodesic into the past in view of the Borde-Gut…
Did time begin? Will time end?
Paul H. Frampton
Did time begin at a Big Bang? Will the present expansion of the universe last for a finite or infinite time? These questions sound philosophical but are becoming, now in the twenty…
On Cyclic Universes
P. H. Frampton
Dark energy in a brane world reconciles an infinitely cyclic cosmology with the second law of thermodynamics. At turnaround one causal patch with no matter and vanishing entropy is…
Deflation at Turnaround for Oscillatory Cosmology
Lauris Baum, Paul H. Frampton
It is suggested that dark energy in a brane world can help reconcile an infinitely cyclic cosmology with the second law of thermodynamics. A cyclic cosmology is described, in which…
Conformal Transformations and Accelerated Cosmologies
James L. Crooks, Paul H. Frampton
A cosmological theory that predicts a late-time accelerated attractor with a constant dark matter to dark energy ratio can be said to solve the Coincidence Problem. Such cosmologie…
Ultra High Energy Cosmic Rays from Sequestered X Bursts
Peter L. Biermann, Paul H. Frampton
Assuming that there is no GZK (Greisen-Zatsepin-Kuzmin) cut-off and that super-GZK cosmic rays correlate with AGN (Active Galactic Nuclei) at cosmological distances, it is speculat…
