One of the regular posters to the Physics forum, MacM, has a theory he calls "UniKEF", short for Universal Kinetic Energy Field. The available material related to his theory can be found here: http://groups.msn.com/McCoinUniKEFTheory/home.htm MacM says that his theory is not complete, but improves on "conventional" physics in a number of respects. He also claims that he has made a number of predictions over the years which have only been recently confirmed (though differently explained) by conventional physicists. He claims that Einstein's theory of relativity is deeply flawed. He also claims that people on this forum are unwilling to give his ideas a fair hearing, presumably because they are too "closed minded". So, I have started this thread for concrete discussion of the details of his theory. Some guidelines if you wish to post to this thread: * This is for discussion of his theory (see the above link). That means that if you wish to claim he is wrong about something, you will need to refer to the specific part of his theory (or posts to this thread) which is wrong, and give an appropriate explanation. * Posts claiming that MacM is a "crackpot", without suitable justification, will be deleted from this thread, as will complaints that this thread has no place in the Physics forum. (My aim here is partially to keep further discussion of UniKEF to one place, rather than have it scattered over many different threads in the Physics forum). * The aim of this thread is not to "develop" MacM's theory for him. It is to examine the current state of the theory with a view to determining if it has any merit as legitimate science. This is not the place to make suggestions for new things MacM might like to explore, or ways he might improve his theory. If you wish to do that, please do so at MacM's site, linked above.
