Oldest Stars May Shed Light On Dark Matter
"The first stars in an early universe filled with moderately
energetic, or "warm," dark matter would probably have developed in long strings, according to a study in the 14 September issue of the journal Science, published by AAAS, the nonprofit science society. In contrast, simulations with slow-moving, cold dark matter generally show the first stars forming in clumps. Efforts are underway to find some of these ancient stars, so it's hypothetically possible that new star discoveries could help clarify whether the universe is made up of warm or cold dark matter." http://www.sciencedaily.com/releases...0913145125.htm Double-A |

Oldest Stars May Shed Light On Dark Matter
"Dark matter" may be an interesting spawn of the Void-Space Paradigm,
one of many such ad hoc 'fixits' necessary if space is indeed a 'void- nothing'. However - if space is *not* a void-nothing but a profoundly real 'Something', a Something that _flows_, then dark matter may very well be dispensed with along with epicycles. What's called gravity is the effect upon matter of *accelerating* spatial flow.. no acceleration = no 'curvature' = no gravity. Irrespective of the actual velocity of the flow, if it does not contain an acceleration (or deceleration) component, there is no gravity, no effect upon matter*. No momentum is imparted to matter embedded in the flow. But light, being massless, is deflected (lensed) by *any* flow whether the flow is accelerating or not. Thus the excessive lensing of distant galaxies that's currently attributed to dark matter would be simple *flow lensing*, not "gravitational" lensing. So flowing space would provide the causal explanation of gravity itself; i.e., the effect *upon matter* when any space flow is under acceleration. It would also explain the excessive lensing of distant galaxies as due to large scale *non-accelerating* flows of the intergalactic medium. *In sub-relativistic speed regimes. oc |
