what they're proposing is "to take a giant philosophical step back and see if a new and more promising direction can be found.
OK, good advice, now do it. If you think there is some massive new physics to be discovered, then discover it. When you do, you will be admired and respected for generations, instead of mocked by me on Slashdot.
Unfortunately this is not true.
An old guy, who happen to be my father and who speaks Serbian only, took that giant step back and found more promising direction - an unified theory which explains all known physical phenomena at subatomic, atomic and cosmic levels, and which is able to theoretically calculate experimentally measured values such as mass, charge, electric arc field, magnet field, gravitation and gravitational field, as a consequence of difference in ether's local pressure and density.
Perhaps one day he will be admired and respected for generations, but so far there's no one willing to even review it - all the journals we contacted dismissed the paper for various bureaucratic reasons such as him not being employed in an university.
For those really interested, here's link (only one chapter translated to English so far):
