This is all fine as long as gravity is the curvature of spacetime, as formulated by Albert Einstein in 1916. Despite the overwhelming consensus of the mainstream, the nature of dark matter and dark energy remains unknown following a century of unsuccessful searches. Is it possible that these constituents are fictitious \u201cghosts\u201d that do not actually exist, but were imagined because Einstein\u2019s equations fail to describe gravity correctly on cosmic scales?<\/p>\n<p>I spent the day today brainstorming through this possibility along the following lines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The mainstream of cosmology asserts that 84% of the matter in the Universe is invisible, labeled as \u201cdark matter\u201d.
