Cosmologists have long wondered whether the Universe will eventually re-collapse and end with a Big Crunch, or expand forever, becoming increasingly cold and empty. Recent evidence for a flat Universe, possibly with a cosmological constant or some other sort of negative-pressure dark energy, has suggested that our fate is the latter. However, the data may actually be pointing toward an astonishingly different cosmic end game. Here, we explore the consequences that follow if the dark energy is… 
Big Crunch, Big Rip – or a Self-Similar Expansion Replenished by Dark Matter and Dark Energy?
Our view of the universe, its origin and development has been a long, humbling sequence of misconceptions – not surprisingly so since this is perhaps the most fundamental question of all. This paper
Constraining non-standard cosmological models
Current observational evidence does not yet exclude the possibility that dark energy could be in the form of phantom energy. A universe consisting of a phantom constituent will be driven toward a
Phantom-like dark energy from quantum gravity
We analyse the emergent cosmological dynamics corresponding to the mean field hydrodynamics of quantum gravity condensates, in the group field theory formalism. We focus in particular on the
Phantom Dirac-Born-Infeld dark energy
Motivated by the apparent discrepancy between Cosmic Microwave Background measurements of the Hubble constant and measurements from Type-Ia supernovae, we construct a model for Dark Energy with

The dark side of the universe is mysterious and its nature is still unknown. In fact, this poses perhaps as the biggest challenge in the modern cosmology. The two components of the dark sector (dark
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
A preliminary study about gravitational wave radiation and cosmic heat death
We study the role of gravitational waves (GW) in the heat death of the Universe. Due to the GW emission, in a very long period, dynamical systems in the universe suffer from persistent mechanical
New Cosmological Probes for Old Fundamental Questions
To a good approximation our Universe is flat and homogeneous, and possesses perturbations which, albeit once upon a time small, have seeded the large-scale structure that we observe around us. We
Interacting Holographic Dark Energy, the Present Accelerated Expansion and Black Holes
Abstract We study the evolution of the universe by assuming an integrated model, which involves interacting dark energy and the holographic principle with the Hubble scale as an IR cutoff. First we
