Chapter 8
Dark Matter Anomaly
B. G. Sidharth and Abhishek Das
Abstract Latest observations by Riess and coworkers in 2017 have reconfirmed
their earlier observation that the universe is accelerating some 8% faster than the
currently accepted cosmological model described. In this chapter, we state again, in
light of a recent paper, that this discrepancy can be eliminated by considering a
universe consisting only of matter and dark energy.
8.1 Introduction
Very recently (Das and Sidharth 2019) Das and Sidharth have shown that the
existence of dark matter is inconsistent with the observation of Riess et al. (2016).
Now, Hubble’s law is regarded as one of the major observational basis for the
expansion of the universe. Later the existence of dark matter was hypothesized by
Zwicky (1933, 1937) who inferred the existence some unseen matter based on his
observations regarding the rotational velocity curves at the edge of galaxies.
Although, Kapteyn (1922) and Oort (1932) had also had derived the same conclusions before Zwicky. Since then, various efforts have been made to prove the
existence of dark matter (cf. ref. Bertone et al. (2005) for detailed review). Recently,
after conducting experiments to detect weakly interacting massive particles
(WIMPs) that interact only through gravity and the weak force and are hypothesized
as the constituents of dark matter, it has been found that such hypotheses lead
nowhere (Akerib et al. 2016).
Interestingly, authors such as Milgrom (1983), Bekenstein (2004) Sidharth
(cf. Sect. 8.3) and Mannheim (2005) have endeavoured to find alternatives to the
widely accepted dark matter. The author Sidharth (2000, 2006a, b) has also given a
suitable alternative to the conventional dark matter paradigm.
