Report Cut The Bullshit In Physics in Physics and Mathematics Posted April 17, 2019 · Edited April 17, 2019 by Moronium Just for the record, this is from CERN: Dark matter--Invisible dark matter makes up most of the universe – but we can only detect it from its gravitational effects Galaxies in our universe seem to be achieving an impossible feat. They are rotating with such speed that the gravity generated by their observable matter could not possibly hold them together...They think something we have yet to detect directly is giving these galaxies extra mass, generating the extra gravity they need to stay intact. This strange and unknown matter was called “dark matter” since it is not visible. Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter... Dark matter candidates arise frequently in theories that suggest physics beyond the Standard Model, such as supersymmetry and extra dimensions. One theory suggests the existence of a “Hidden Valley”, a parallel world made of dark matter having very little in common with matter we know. If one of these theories proved to be true, it could help scientists gain a better understanding of the composition of our universe and, in particular, how galaxies hold together. https://home.cern/science/physics/dark-matter Who would have guessed that "theories" involving "extra dimensons" and "parallel worlds," would have come out of this, eh? Not really a serious question--just rhetorical. Such "explanations" seem to be a routine part of physics these days. I have a theory, too. Ghosts are causing all of this. By definition they are invisible and can't be seen, so I will have to grant that I can only infer their presence from observable effects, but, still..... The article notes that "If one of these theories proved to be true..." I figure my theory has just as much chance of being "proved to be true," as the others, ya know? Where's my Nobel Prize?
