[math-fun] The bombshell from yesterday
No, not THAT bombshell, but this one, regarding *dark matter* and the Holographic Principle: https://science.slashdot.org/story/16/11/09/0031212/new-theory-of-gravity-mi... https://arxiv.org/pdf/1611.02269.pdf New Theory of Gravity Might Explain Dark Matter (phys.org) 111 Posted by BeauHD on Wednesday November 09, 2016 @02:00AM from the spacetime dept. vikingpower writes: Dutch prodigy and Amsterdam University Professor Erik Verlinde published a paper on arXiv yesterday, November 7, titled "Emergent Gravity and the Dark Universe." In the paper, Verlinde derives gravity from the so-called Holographic Principle, which -- simply put -- states that gravity emerges from the interplay between and entropy re-arrangement of sub-atomic "strings" that live in a negatively curved spacetime. At that level [...] spacetime and gravity are emergent from an underlying microscopic description in which they have no a priori meaning." Most importantly, Verlinde's paper has as a consequence that dark matter, nemesis of many an astronomer, is nothing more than an illusion.
