Dark Matter and Dark Energy as a Derivate from Cosmic Photon Radiation | Chapter 05 | Theory and Applications of Physical Science Vol. 3

For many decades now, intensive efforts have been undertaken by physicists and cosmologists around the world to investigate dark matter (DM), without noticeable success to date. This situation leads me to believe that one of the assumptions underlying the current doctrine in physics may well be erroneous or incomplete – since a breakthrough in this field of physics and cosmology would otherwise surely have already taken place by now.

For the past years, the CERN Nuclear Research Centre has set itself the task of using the LHC (upgraded to 13 TeV) to investigate the still completely mysterious phenomenon of dark matter. The researchers at CERN favour the assumption – shared by the majority of physicists and cosmologists, that DM consists of massive non-baryonic particles (so-called WIMPs, Weakly Interacting Massive Particles) hitherto completely unknown to us, which produce a non-baryonic, static gravitational field distributed throughout the entire cosmos.

I cast doubt on the above assumption that DM is massive in nature. As this paper will show, DM can be far better (and more simply) explained in terms of a non-massive gravitational derivate of those photons consumed in the expansion of cosmic space (by performing the work of expansion), those photons thereby being transformed into static physical quantities. This gravitational derivate creates a free gravitational field (decoupled from the other forces of nature) of non-baryonic, static nature, regionally varying in intensity, and this is known as dark matter.

Second-order Gauge-invariant Cosmological Perturbation Theory: Current Status Updated in 2019 | Chapter 01 | Theory and Applications of Physical Science Vol. 3

The current status of the recent developments of the second-order gauge-invariant cosmological perturbation theory is reviewed. To show the essence of this perturbation theory, we concentrate only on the universe filled with a single scalar field. Through this review, we point out the problems which should be clarified for the further theoretical sophistication of this perturbation theory. This review is an extension of the review paper [K. Nakamura, “Second-Order Gauge-Invariant Cosmological Perturbation Theory: Current Status”, Advances in Astronomy, 2010 (2010), 576273.]. We also expect that this theoretical sophistication will be also useful to discuss the future developments in cosmology as a precise science.
