The Dark Energy Universe

TL;DR

This paper discusses a model of the universe driven by dark energy with a small cosmological constant, challenging the dark matter paradigm and supported by supernova observations that confirm an accelerating universe.

Contribution

Introduces a dark energy-driven universe model with a small cosmological constant, contrasting with the dark matter paradigm and supported by observational evidence.

Findings

Dark energy may eliminate the need for dark matter.

Supernova observations confirm an accelerating universe.

The model aligns with Nobel-winning astronomical data.

Abstract

Some seventy five years ago, the concept of dark matter was introduced by Zwicky to explain the anomaly of galactic rotation curves, though there is no clue to its identity or existence to date. In 1997, the author had introduced a model of the universe which went diametrically opposite to the existing paradigm which was a dark matter assisted decelarating universe. The new model introduces a dark energy driven accelarating universe though with a small cosmological constant. The very next year this new picture was confirmed by the Supernova observations of Perlmutter, Riess and Schmidt. These astronomers got the 2011 Nobel Prize for this dramatic observation. All this is discussed briefly, including the fact that dark energy may obviate the need for dark matter.
