as far as i know, Tony Peratt remains extant. as with pretty much all the EU/ES/EC speculations (which i know lots about as i know most of the principals in the area), there is no substance, just hand waving speculations. they eschew mathematics, which for 2400 years has been closely intertwined with physical science. hence, they have no predictive capability and no serious models for any process. they are not rejected by mainstream physics as almost no professional physicists have even heard of the EU, etc. they castigate Einstein categorically although they’re not aware that Einstein made major discoveries in a half dozen different subjects. what they don’t like are one or both of the relativity theories although few, if any, of them have any technical understanding of the theories. the relativities & quantum mechanics are among the most accurate theories in modern physics, confirmed experimentally time & time again. and used, like calculus, on a daily basis. it appears as though the EU fans really want physics to end in the 19th century and look for explanations of all phenomena in terms of the pre-20th century physics. they’re just wrong or as Wolfgang Pauli might have said, there’s so little there that it’s not even wrong. i suspect that the recent interest in the topic is part of trending “death of expertise”, as it’s being called. anyone can put anything on the Internet and it has a leveling effect where in many, if not most, people feel that their opinion is a good as that of anyone else; as good as the opinions of professional scientists who, as have i, have worked in the field for half a century. ultimately it matters little because science will move along and the fringe will remain, well, the fringe
