Modern physics has lost it's way and is vanishing up it's own arsehole in my opinion.
And I say that having studied physics at university.
None of these kind of conjectures can be related to empirical experimentation in any meaningful way
so in this sense they have become decoupled from the scientific method and hence can no longer be considered actual science.
Once you start down this slippery slope you can come up with any old bullshit you like as long as no experiment is possible
in the foreseeable future to contradict it. But meanwhile you still keep getting your grant cheques of course!
