It has recently been claimed that the Hubble sphere represents a previously unknown limit to our view of the universe, with light we detect today coming from a proper distance less than this ‘cosmic horizon’ at the present time. By considering the paths of light rays in several cosmologies, we show that this claim is not generally true. In particular, in cosmologies dominated by phantom energy (with an equation of state of ω < −1) the proper distance to the Hubble sphere decreases, and light… Expand

The gravitational horizon for a Universe with phantom energy
The Universe has a gravitational horizon, coincident with the Hubble sphere, that plays an important role in how we interpret the cosmological data. Recently, however, its significance as a trueExpand

Many cosmological measurements today suggest that the Universe is expanding at a constant rate. This is inferred from the observed age versus redshift relationship and various distance indicators,Expand
Space–time curvature and the cosmic horizon: derivations using the Newtonian world and the Friedmann–Robertson–Walker metric
Several relationships describing the distance versus time dependence of the cosmic horizon (Rh) for an expanding universe have been published within the past two decades. Some are based on theExpand

It has recently been claimed that relativity’s most famous equation, $$E=mc^2$$ , has a cosmological basis, representing the gravitational binding energy for a particle to escape from the origin toExpand
Why the Rh = ct cosmology is unphysical and in fact a vacuum in disguise like the milne cosmology
Recently, Melia and his coworkers have proposed the so-called R_h = ct cosmology where the scale factor of the universe is a(t) ∝ t and the spatial part is flat. This model also implies a fixedExpand
On recent claims concerning the Rh = ct Universe
The R_h=ct Universe is a Friedmann-Robertson-Walker (FRW) cosmology which, like LCDM, assumes the presence of dark energy in addition to (baryonic and non-luminous) matter and radiation. Unlike LCDM,Expand
Ray tracing in FLRW flat space-times
In this work we take moves from the debate triggered by Melia et al [9]. and followed by opposite comments by Lewis and Oirschot [10,11]. The point in question regards the role of the Hubble horizonExpand

Why the Big Bang Model does not allow inflationary and cyclic cosmologies though mathematically one can obtain any model with favourable assumptions
Abstract Various versions of standard Big Bang Model (BBM) including the current LCDM cosmology require an “inflationary” phase for the nascent universe ( Δ t ∼ 10 - 32  s) during which the size ofExpand
Causal horizons in a bouncing universe
As our understanding of the past in a bouncing universe is limited, it becomes difficult to propose a cosmological model which can give some understanding of the causal structure of the bouncingExpand


Photon Geodesics in FRW Cosmologies
The Hubble radius is a particular manifestation of the Universe’s gravitational horizon, Rh(t0) ≡ c/H0, the distance beyond which physical processes remain unobservable to us at the present epoch.Expand

Within the context of standard cosmology, an accelerating universe requires the presence of a third "dark" component of energy, beyond matter and radiation. The available data, however, are stillExpand
Through the looking glass: why the 'cosmic horizon' is not a horizon
The present standard model of cosmology, Λ cold dark matter (ΛCDM), contains some intriguing coincidences. Not only are the dominant contributions to the energy density approximately of the sameExpand
The cosmic horizon
The cosmological principle, promoting the view that the Universe is homogeneous and isotropic, is embodied within the mathematical structure of the Robertson‐Walker (RW) metric. The equations derivedExpand
