Which Mysteries Might MACHOs and PLANCHOs Solve?

What previous evidence for stellar mass microlenses? You keep bringing this up but lack literature references. If the Galaxy has huge populations of unbound ultracompact objects with masses in the 0.1 to 1.0 solar mass range (MACHOs) and Neptune/Jupiter mass range (PLANCHOs), then several key astrophysical enigmas might be solved by their existence. A partial list of those mysteries that MACHOs and PLANCHOs might explain would include the following. The composition of the galactic dark matter Which brings up more questions than it solves, if you think about it for a moment. 1) How can baryonic dark matter leave an imprint on the CMB, and take place in large scale structure formation _as_ the first stars are forming? 2) How can this kind of baryonic dark matter completely escape the SuperMACHO survey which was specifically designed to look for these events? 3) How can all these objects escape detection by infrared surveys? 4) How did all these objects form? The ubiquitous 1-100 day variability of quasars Uh, no. The variability is not due to lensing. The factor of 6 excess in the ARCADE 2 radio background observations Factor of 6 relative to what? The origin of cosmic rays Which cosmic rays? There's a spectrum that spans about 23 orders of magnitude. The composition of the recently discovered infrared-faint radio transients A significant unidentified component of the X-ray background A significant unidentified component of the Gamma-ray background Ubiquitous Gamma-ray burst phenomena The origin of ubiquitous unidentified optical transients So these objects are bright in the radio, IR, optical, X-ray, and gamma portions of the spectrum? Are you SURE you understand what 'dark matter' means? It would seem prudent at this point to put as much effort into the dark matter search for “primordial” Kerr-Newman ultracompact objects as has been expended in the unsuccessful 35-year effort to find any form of “WIMP” or exotic particle dark matter. People have looked for primordial black holes, as a trivial literature search would reveal. Nada. Robert L.
