WSU: The Dark Side of the Universe with Michael Turner

Theoretical cosmologist Michael Turner, who coined the term "dark energy,” explores how the combination of cosmology and particle physics will help us understand the origin and evolution of the universe. #WorldSciU

could black holes interact magnetically spreading themselves apart as more of them pops up

How can we rule out photons moving through empty space that have not struck an object that would reflect it?

Novel Dark Matter Hypothesis

Dark Matter is simply unaccounted for gravity. GR states that gravity is the consequence of the curvature of spacetime. Is it possible that the structure of spacetime itself could be warped without the presence of mass? Spacetime has been shown to react like a fabric by warping, twisting, and propagating independently of mass, and all have been proven with observations from gravitational lensing, frame dragging, and now gravitational waves! Fabrics can be stretched, pressured, and/or heated to the point of causing a deformation. All of these conditions were extreme during inflation, so it is plausible that the “fabric” of spacetime analog could extend having its elastic property have hit a yield point.

Therefore, if gravity is the consequence of the warping of spacetime, and fabrics can be permanently overstretched, then those empty warped geodesics would create gravitational wells independent of mass. My hypothesis of DM is subatomic black hole imprints of the quantum fluctuations that popped in at the moment of inflation. These would be clouds of quantum sized floating fixed geodesics, so they couldn’t expand or evaporate. Perhaps nothing has been detected because there is nothing to detect, and GR wouldn’t require modification of mass interactions because DM would just be an extension of how space-time behaves at extreme conditions. No WIMPS, no MOND, no parallel universes, just empty spacetime deformations that produce gravitational wells to help jump start galaxy accretion processes.

Everyone knows E = m x c (squared). So, m = E / c (squared). So, dark matter is concentrated dark energy, and dark energy is diffused dark matter. The corollary is ordinary visible matter is concentrated dark matter.
