The Universe

The standard big bang cosmology has the universe created out of a primeval explosion that not only created matter and radiation but also spacetime itself. The big bang event itself cannot be discussed within the framework of a physical theory but the events following it are in principle considered within the scope of science. The recent developments on the frontier between particle physics and cosmology highlight the attempts to chart the history of the very early universe.

Opening Up

This chapter introduces physical cosmology as the attempt to make sense of the large-scale nature of the material world by the methods of the natural sciences. It explains that physical cosmology operates under the special restrictions of astronomy, which is considered successful in sister fields, such as stellar astronomy and particle physics. It cites the substantial progress of cosmology as an enterprise in physical science, although the advances certainly have moved around considerable gaps in one's understanding. The chapter details how cosmology inherits from basic physics the more ancient and honorable tradition of attempts to understand where the world came from, where it is going, and why. It reviews believable evidence that the universe is expanding, the space between the galaxies opening up, and that this expansion traces back to a hot dense phase, the big bang.

Origin Of The Universe

The origin of the universe and nuclear synthesis are discussed in this paper. The concept of the “Big Bang” is introduced in cosmology from observational evidence that the universe is expanding. The language of elementary particle physics is used to describe the evolution of the universe starting at a very small fraction of a second after the "Big Bang”. Various “Eras” are identified during which certain nuclear processes predominate. At a later stage the remarkable nuclear synthesis of carbon takes place, leading to the evolution of other elements. Neutrino measurements are important to validate physical theories in this field and some results of such measurements by the WITS-CSIR Schonland Research Centre are presented.

Dynamical Dark Energy

The emergence of a highly improbable coincidence in cosmological observations speaks of a remarkably simple cosmic expansion. Compelling evidence now suggests that the Universe’s gravitational horizon, coincident with the better known Hubble sphere, has a radius improbably equal to the distance light could have traveled since the Big Bang. The confirmation of this unexpected result would undoubtedly herald the influence of new physics, yet appears to be unavoidable after a recent demonstration that the Friedmann–Lemaître–Robertson–Walker metric is valid only for the so-called zero active mass equation of state. As it turns out, a cosmic fluid with this property automatically produces the aforementioned equality, leaving little room for a cosmological constant. The alternative — a dynamical dark energy — would suggest an extension to the Standard Model of particle physics and a serious re-evaluation of the Universe’s early history.

Autistics and the plane of complex numbers suggest that if the accelerating expansion of our universe and the anti-universe succeeded a coasting expansion 8.8 billion years after the Big Bang, an accelerating contraction will start in 3.8 billion years. Mirroring the expansion phase, a coasting contraction of the two universes in cosmic space will come up in 12.6 billion years. The end of the fourth section of 8.8 billion years will host two Big Crunches, two White Holes, and a new Big Bounce. The reason for that paradox solves the “cosmological constant problem” and joins general relativity to particle physics. The z-plane and autism can also help us cross science with the arts and religion; retain the search for truth, beauty, and goodness by our descendants; and reach the message of progress buried in the Ark of the Covenant, the Great Pyramid, and Giza’s Sphinx: A selfish brain hides a selfless heart.

Abstract The IceCube Neutrino Observatory is a large Cherenkov detector instrumenting $$1\,\mathrm {km}^3$$ 1 km 3 of Antarctic ice. The detector can be used to search for signatures of particle physics beyond the Standard Model. Here, we describe the search for non-relativistic, magnetic monopoles as remnants of the Grand Unified Theory (GUT) era shortly after the Big Bang. Depending on the underlying gauge group these monopoles may catalyze the decay of nucleons via the Rubakov–Callan effect with a cross section suggested to be in the range of $$10^{-27}$$ 10 - 27 to $$10^{-21}\,\mathrm {cm^2}$$ 10 - 21 cm 2 . In IceCube, the Cherenkov light from nucleon decays along the monopole trajectory would produce a characteristic hit pattern. This paper presents the results of an analysis of first data taken from May 2011 until May 2012 with a dedicated slow-particle trigger for DeepCore, a subdetector of IceCube. A second analysis provides better sensitivity for the brightest non-relativistic monopoles using data taken from May 2009 until May 2010. In both analyses no monopole signal was observed. For catalysis cross sections of $$10^{-22}\,(10^{-24})\,\mathrm {cm^2}$$ 10 - 22 ( 10 - 24 ) cm 2 the flux of non-relativistic GUT monopoles is constrained up to a level of $$\Phi _{90} \le 10^{-18}\,(10^{-17})\,\mathrm {cm^{-2}\,s^{-1}\,sr^{-1}}$$ Φ 90 ≤ 10 - 18 ( 10 - 17 ) cm - 2 s - 1 sr - 1 at a 90 % confidence level, which is three orders of magnitude below the Parker bound. The limits assume a dominant decay of the proton into a positron and a neutral pion. These results improve the current best experimental limits by one to two orders of magnitude, for a wide range of assumed speeds and catalysis cross sections.

ABSTRACT A new bound dark energy (BDE) cosmology has been proposed where the dark energy is the binding energy between light meson fields that condense a few tens of years after the big bang. It is reported that the correct dark energy density emerges using particle physics without fine-tuning. This alone makes the BDE cosmology worthy of further investigation. This work looks at the late-time BDE predictions of the evolution of cosmological parameters and the values of fundamental constants to determine whether the cosmology’s predictions are consistent with observation. The work considers the time period between a scale factor of 0.1 and 1.0. A model BDE cosmology is considered with current-day values of the cosmological parameters well within the observational limits. The calculations use three different values of the current-day dark energy equation of state close to −1. All three cases produce evolutions of the cosmological parameters and fundamental constants consistent with the observational constraints. Analytic relations between the BDE and cosmological parameters are developed to insure a consistent set of parameters.

Empedocles managed to reconcile the antinomies between the Heraclitean becoming (the constant change) and the Parmenidean Being (the constancy) by introducing four unchangeable primary substances of matter: earth, water, air, and fire, later called elements, and two types of forces, love and strife. Change was produced when the opposite action of the forces mixed and separated the unchangeable elements in many different ways, an idea in basic agreement with modern chemistry or, more fundamentally, with the standard model of particle physics. Everlasting cosmological cycles, described in his unique cosmology, could have addressed successfully the deceptively simple question, Why is the sky dark at night? (known as Olbers’s paradox), before the cosmology of the big bang had it figured out in the twentieth century. Four primary substances of matter for Empedocles, but infinitely many for the mind of Anaxagoras, and everything is in everything.
