“…A graph of similar shape was shown in Figure 2 of the seminal paper of the heuristic flat space-time cosmology model [14]. Crucially, an accelerating cosmic expansion would demonstrate a flatter curve in such a graph.…”

This paper briefly discusses existing problems with the theory of general relativity despite remarkable accuracy in most of its applications. The primary focus is on existing problems in the field of cosmology, particularly those pertaining to expectations of global cosmic space-time curvature in the absence of observational proof. The discussion centers on Krogdahl's recent Lorentzinvariant flat space-time cosmology and its superiority to general relativity with respect to accounting for global cosmic space-time flatness and dark energy observations. The "cosmological constant problem" is briefly addressed as a problem for general relativity with respect to particle physics and quantum field theory. Finally, two very specific validation predictions in favor of Krogdahl's flat space-time cosmology are made with respect to ongoing studies, including the dark energy survey (DES).

With reference to Planck scale Hubble parameter, super luminal expansion speeds, super luminal rotation speeds, Mach's principle and Holographic principle, we review the current cosmological observations with eight simple assumptions. By understanding Yuri N. Obukhov and V.A. Korotky proposed cosmic rotational effects of polarization of radiation due to massive bodies, to some extent cosmic rotation can be deep-rooted in an observational approach and the ratio of current angular velocity and Hubble parameter can be estimated. It is possible to show that, at H0 =70 km/sec/Mpc, current cosmic temperature, age, radius, mass, mass density are 2.721 K, 4.41x10 17 sec, 90 billion light years, 1.14654x10 54 kg, 0.0482 times the current critical density respectively. Clearly speaking, current universe seems to constitute 267 Hubble spheres. Important point to be noted is that, current rotational kinetic energy is 0.6667 times the current critical energy. Based on the estimated current mass density and current rotational kinetic energy, current cosmic dark matter density can be shown to be 0.2851 times the current critical density. These numerical coincidences cast serious doubt on the on the real existence of currently believed 'dark energy'. Initial and current expansion speeds are 3x10 8 m/sec and 3.56x10 9 m/sec respectively. With increasing cosmic age and increasing cosmic expansion speed, current universe is expanding with a speed of 11.885c. By knowing the time to time future cosmic temperatures, future Hubble parameters and corresponding future cosmic expansion speeds can be estimated and thus future expansion speed can be understood. Starting from 'speed of light', our model assumes a continuous increase in expansion speed and attains a current radius of 90 billion light years (without inflationary concepts) and casts a serious doubt on the actuality of currently believed 'inflation'.

“…Flat Space Cosmology (FSC) is a mathematical model of universal expansion which has proven to be remarkably accurate in comparison to observations [1] [2] [3] [4] [5]. FSC was initially developed as a heuristic mathematical model of the Hawking-Penrose idea that an expanding universe arising from a singularity state can be modeled as a time-reversed giant black hole.…”

“…The purpose of this paper is to show how the FSC Friedmann equations evolve further from Equation (1) and what they might imply with respect to the fundamental nature of gravity, dark energy and dark matter. Before doing so, however, it is useful to review the five current assumptions of FSC and its observational correlations.…”
