As for temporal asymmetry, from what I can remember from my education, it is a fact (see the Big Bang, the lack of white holes, and thermodynamics) and it is the holy grail of theoretical physics. One of my professors used to say that the failure to produce temporal asymmetry is one of the reasons string theory is doomed.
As to faster-than-light travel, again it is locally assumed to be impossible and it is more basic than time translation symmetry or energy conservation.
However, Roger Penrose wrote in The Emperor's New Mind that near the big band the curvature of spacetime was very smooth while in the course of cosmic evolution it becomes more and more "wrinkled". He associated this to the Weyl Curvature Tensor. I don't know the status of this hypothesis.

But my intuition says "no." Because if you violate spacetime symmetry, you get FTL travel and energy non-conservation. And those are big no-nos in general relativity.
The Soviets did not press their colonies painfully in the economic sense. Rather contrary - they were supplying oil, fertilizers, dambs cheaply, with not that much in return. The fall of the USSR was quite a liberation for Russia - but it still has to match known Western colonialism pains.
However, this algebra requires ruble-denominated imports to be a minority of imports to these countries. Which would be strange, considering the mechanics which usually govern the foreign trade.
A more probable story is that the newsies weren't paying attention. Because you'd also get the result described (that the value of remittances drop while import prices rise) if the value of the local currency drops against its trade-weighted basket while nominal remittances drop because the people who send home money see their cost of living going up faster than their income, because the ruble drops against its foreign trade partners.
But that story - if that is indeed what happened here - is much more complicated and nuanced than the simple 'depreciation bad' angle the newsie picked for this piece.
The feeble ruble has helped push down currencies around the region, sometimes by double-digit figures.
Either David Cameron sought this battle or he was asleep on the job. It is hard to say which is worse
It is extremely important to keep all this firmly in mind when considering the furore over the EU's demand for Britain to pay a further £1.7bn into the European budget by the start of December. The statistical revisions whose consequences are causing so much consternation to the Conservatives in the European context are in fact the self-same revisions whose effects they will cheer to the rafters when the chancellor delivers his pre-election autumn statement in December. In both cases, they are the product of the same mechanical statistical exercise. So in that sense it is no more valid to pretend that the EU budget effect of these revisions is proof of the wickedness of Brussels than it is to pretend that the UK GDP effect of these same revisions is proof of Mr Osborne's wise management of the British economy. Both these claims are old-fashioned opportunism.
Because the problem isn't the price movement, or the exchange rate movement, or whatever.
The problem is that the Russian trade bloc is being embargoed, and the Russian trade bloc isn't sufficiently independent of the American world system to just shrug and go about its business.
So it's gonna suck to be a peripheral member of the Russian trade bloc for the foreseeable future. A currency union would not make it suck less. It would just mean that Russia, being the senior partner in the trade bloc, would find some other way to make the colonies bear a disproportionate share of the pain, so the center does not have to.
What I'm getting at here is that the question "where do the laws of physics come from" is not a well specified question, in the same way that "this statement is false" is not a well-specified Boolean statement.
I could tell a story about how imposing temporal and spatial symmetry on the timeless formulation of the quantum Hamiltonian makes the fundamental laws of physics follow in a very satisfying and parsimonious manner.
(Specifically, conservation of energy, conservation of momentum, conservation of angular momentum, and the 1:1 mapping of phase space density to probability distribution all follow relatively straightforwardly, and you can construct pretty much all of physics outside of general relativity from those fundamentals.)
If I can find my old lecture notes I can even show you the operator algebra involved.
But that just gets us one turtle deeper, because the geometric properties of the universe are themselves just "laws of physics." In principle you could come up with all sorts of geometries and apply them to the quantum Hamiltonian (though the math will probably become intractable pretty quickly).
3 California sheriffs' deputies shot, 1 dies - SFGate
SACRAMENTO, Calif. (AP) -- An assailant shot and killed a Sacramento County sheriff's deputy and wounded two other deputies along with a bystander Friday during a series of shootings that spanned more than 30 miles through two California counties.
