    OTOH (I was just reading the other day), cats can’t even see red (looks grey to them) … only green and blue. Looks as though higher-freq visible light worked just fine for Feliformia. The organs/antennae needed to send and/or receive RF would be highly ungainly for speedy smaller predatory mammals.

    Who knows - maybe some of the dinosaurs -did- use RF?! High EMF from solar CME’s might have burned out their receptors.








  • Yeah, I’m not paying a whole lot of credence to the cosmology department these days, they’re too busy using Elmer’s Glue to keep their whole story from falling apart.

    I’m not so sure about the whole ‘photon’ thing anymore either … an individual, no-mass, single-point thing that can survive travelling through that universe out there for -billions of years- ? The math works, but does the model, really?

    Right on about the life thing too.
