Heim's theory of quantum gravity, of which there was a brief flurry of
discussion awhile back. I don't understand the theory itself of course
- apparently professional physicists don't understand it either - but
the following is what I picked up back then:<br>
<br>
Apparently the theory predicts the masses of the fundamental particles and this is its main claim to fame.<br>
This strikes me as dubious on anthropic grounds for what that's worth.<br>
<br>
Apparently it predicts a neutral electron. The neutrino could be
regarded as such, but I gather from context that this is supposed to
have the same mass as the electron and positron, and no such particle
has been observed.<br>
<br>
It's been claimed that the theory predicts the masses of the
fundamental particles to greater accuracy than would be allowed by the
input data available in Heim's time, which would indicate there was
something fishy going on.<br>
<br>
Analysis is difficult because Heim used some strange nonstandard mathematics that nobody can really follow.<br>
<br>
There was talk about the possibility of testing the theory (which would
obviously be the ideal thing to do, if practical). I don't know what
the story is on that at the moment.<br>
