Talk is cheap and accomplishments speak volumes.
If you think talk is cheap, then online message boards are clearly not the place for you. Anonymity is a system with both virtues and faults; in my opinion, its usual faults have not been on display in this thread. You are welcome to disagree, but the general attitude of "I don't converse with anyone until I have looked them in the eye" isn't going to be productive. You are also welcome to go start a thread on a non-anonymous message board somewhere.
You're reading a conversation about the ads, the web page, the excerpts. Witt himself participated in the conversation. Imagine that you just walked into a bar, and twenty people you've never met are sitting around with a copy of "Discover" and access to Witt's web page and to Physical Review Letters. They're talking about the ad. Some of them sound like they know what they're talking about, and are saying things you can confirm for yourself. Some of them are saying things you know to be incorrect. You're free to make your own judgments---so and so seems to have a point, so and so keeps refusing to cite sources, so and so is evading questions. I'm sure you make such judgements all the time, although perhaps not on life-or-death questions like "will I get into a plane with this person"---but this isn't one of those questions. You're also welcome to chime in---with criticism, counterarguments, requests for clarification, whatever.
But you're not free to smash a bottle on the bar and demand that the conversation conform to your standards.
Anyway. There's no substitute for actually knowing physics when it comes to amateur assessment of physics. If you're inclined to trust credentials, though, your task is easy: most credentialed physicists agree on the big stuff. Anyone saying that the following things are "wrong" is going to be in explicit disagreement (and know, and admit, that they're in disagreement) with the vast majority of Ph.Ds: quantum mechanics, special relativity, general relativity, the Big Bang, "standard model" particle physics, "standard model" lambda-CDM cosmology. If you're going to run on credentials alone, then you should be even quicker to dismiss Witt than we are, because he only has a BSEE, and the mainstream physics that Witt rails against obviously have lots of Ph.Ds. The "accomplishments" of mainstream physics should speak volumes, if that's the way you're judging.As an amateur I can not understand your arguments.
So, you're going to have to clarify your goals a bit. You're looking for a credentialed Ph.D. physicist to tell you, on the record, whether a BSEE software CEO has solved all of physics or not. I think Witt himself can give you an honest answer to that: he'll probably say, "No, obviously no mainstream physicists have adopted my paradigm yet, that's why I haven't been able to publish a paper."
Of course, if you want to be an amateur physicist and still be open to the idea of finding theories in defiance of mainstream physicists ... well, then you're in the same bind as "amateur stock pickers" and "amateur art buyers" and "amateur currency traders". You'll be bombarded by 1000 mutually-contradictory theories, then try to pick the right one with fairly little information and analysis to guide you. Full-time professional brokers/buyers/traders will be bombarded by the same theories, but they've got a huge amount of experience with the analysis. Go ahead and make your picks, but your lack of information is going to make you prone to mistakes. You might get lucky, but you don't sound like the kind of person who wants to rely on luck.
