One of the things that sometimes portends the collapse of civilization is some realization that not only are things not going to get better, but they are going to get worse. For example, Lee Smolin, the guy who has tried to take up the bad-boy-of-physics tights and cape left vacant by the discorporation of Richard Feynman has advanced a pin prick in the expanding helium balloon of the folks pushing the multi-universe ideas.

“there is only one universe; all that is real is real in a moment, as part of a succession of moments; and everything that is real in a moment is a process of change leading to the next or future moments.”
IOW, we only have one universe and it isn’t stationary.
Sorry, but I keep coming back to the testability thing. Despite folks finding a few applications for string theory, none having to do with cosmology, it is still unproven and we still have only quantum mechanics and relativity as proven (recent) theory. And yes, I know that ‘recent’ is the beginning of the last century but until there is some compelling verification I am going to consider what the string theorists do as serious, but still, science fiction.
That is not to say that I don’t consider the multiverse thing to be invalid – or valid, for that matter. We still don’t know which interpretation to put to quantum mechanics: Copenhagen (Bohr); Popper; or interaction (Cramer). I personally don’t like the Copenhagen interpretation because it reeks of mysticism. The Popper interpretation posits an infinity of universes based on one of the definitions of probability but has problems in not specifying how big a probability event has to be to split one universe into two. And finally, the interaction interpretation has some hard thinking about time involved that humans may just not be capable of being embedded in it; IOW, it may actually need the observer thing from the Copenhgen interpretation.
I should comment that the Popper multiverse is quite different from the multiverse Smolin is referring to. I think. Maybe.
Nor do I throw out the idea that the universe (reality) is non-stationary. Stationarity is a stochastic (probabilistic ) concept that says that the stochastic processes of a system (the universe may be a system, that’s another head banger) do not change over time. Not that the state of the universe is fixed, but only that the processes that determine the instantaneous state of the universe are. There is also the strong implication that the state of the universe is recurrent but not necessarily periodic. (That means the same state may occur more than once but the behavior displayed does not have to be regular like a sine wave or a pendulum.) The big leap here is that the ‘rules of physics’, as we see them at any time, are the (assumed) stochastic processes of the universe.
So to quote Robert Heinlein, “waiting is.”
Speaking of which, we have sort of given up waiting for all those extraterrestrial out there to communicate with us. This is related to the Fermi paradox, named after the guy who is half blamed for Fermi-Dirac statistics, which apply to what are called fermions and are characterized by having half integer imherent spin.  But one of Fermi’s flights of fantasy had to do with why we had not seen any evidence of intelligtent life in the universe (he excluded humanity from this.) Now, some researchers at Pennsylvania State U have offered up that the reason for this may be because of environmental restrictions. Simply put, if you are as stupid as humanity then you quickly use up your natural resources and don’t have any surplus to communiate with. [Link]
Now, while this is a compelling theory, I am not yet ready to abandon the idea that no one has communicated with us for the simple reason that we are not good neighbors. But then, that may be the same as the chaps at Penn State advanced?
Anyway, the fun part is that not only is the universe smaller than we would like it to be, it’s also much harsher.
 The other type of particles are called Bosons, have integer valued inherent spin, and obey Bose-Einstein statistics. Fermi, as one would surmise, was Italian, and Bose Indian. Some folks, humorists and maniacs in general, offer that the difference between half and whole integer spin properties is descriptive of the differences between occidental and oriental socieies.
