Current evidence suggests that the cosmological constant is not zero, or that we live in an open universe. We examine the implications for the future under these assumptions, and find that they are striking. If the universe is cosmological constant-dominated, our ability to probe the evolution of large-scale structure will decrease with time; presently observable distant sources will disappear on a timescale comparable to the period of stellar burning. Moreover, while the universe might expand… 
A solution to the cosmological problem of relativity theory
After nearly a century of scientific investigation, the standard cosmological theory continues to have many unexplained problems, which invariably amount to one troubling statement: we know of no
Dark Energy and the Observable Universe
We consider ever-expanding big bang models with a cosmological constant, Λ, and investigate in detail the evolution of the observable part of the universe. We also discuss quintessence models from
Life, the Universe, and almost Everything: Signs of Cosmic Design?
Why did the big bang occur, why do the laws and constants of nature as well as the boundary conditions seem so fine-tuned for life, what is the role of intelligence and self-consciousness in the
The Future History of the Universe
This chapter reviews our current understanding of the long term future of the universe and its constituent astrophysical objects. In particular, we consider the evolution of planets, stars, galaxies,
Cosmological immortality: how to eliminate aging on a universal scale.

This paper discusses in how far an intelligent civilization could stay alive by engaging in stellar, galactic and universal rejuvenation and argues that leaving acosmological legacy via universe making is an inspiring and promising narrative to achieve cosmological immortality.
The return of a static universe and the end of cosmology
We demonstrate that as we extrapolate the current ΛCDM universe forward in time, all evidence of the Hubble expansion will disappear, so that observers in our “island universe” will be fundamentally
Dark Energy And Life's Ultimate Future
The discovery of the present accelerated expansion of space changed everything regarding cosmology and life's ultimate prospects. Both the optimistic scenarios of an ever (but decelerated) expanding


The observational case for a low-density Universe with a non-zero cosmological constant
OBSERVATIONS are providing progressively tighter constraints on cosmological models advanced to explain the formation of large-scale structure in the Universe. These include recent determinations of
The End of the Age Problem, and the Case for a Cosmological Constant Revisited
The case for an open universe versus a flat universe with nonzero cosmological constant is reanalyzed, following new globular cluster dating results that now suggest a dramatically reduced lower
Entropy in an Expanding Universe
The question of how the observed evolution of organized structures from initial chaos in the expanding universe can be reconciled with the laws of statistical mechanics is studied, with emphasis on
Time without end: Physics and biology in an open universe
The general conclusion of the analysis is that an open universe need not evolve into a state of permanent quiescence and life and communication can continue for ever, utilizing a finite store of energy, if the assumed scaling laws are valid.
The cosmological constant is back
A diverse set of observations now compellingly suggest that the universe possesses a nonzero cosmological constant. In the context of quantum-field theory a cosmological constant corresponds to the
Creation and structure of baby universes in monopole collisions
Under certain circumstances, the collision of magnetic monopoles, topologically locked-in regions of false vacuum, leads to topological inflation and the creation of baby universes. The future
Results from the High-z Supernova Search Team
Eternity is unstable
We show that if the Universe expands forever, it will become increasingly irregular in the far future. In particular, we demonstrate that the Hawking black hole evaporation process causes a vortical
Measurements of Ω and Λ from 42 High-Redshift Supernovae
We report measurements of the mass density, ΩM, and cosmological-constant energy density, ΩΛ, of the universe based on the analysis of 42 type Ia supernovae discovered by the Supernova Cosmology
