Boundary conditions. Current laws of physics, as we now formulate them, aren't valid in certain places, such as Big Bang or event horizon. So if you ask what's beoynd them, the answer would be along the lines "Don't know". That doesn't invalidate current theories, just puts limits to where you can use them. (like, Newtonian versus relativistic physics)

The event horizon of a black hole, as far as anyone can tell, anyway, doesn't do anything important to either entropy or conservation of energy; when mass or energy goes over the event horizon of a black hole, it increases the mass of the black hole accordingly. Current theory (I'm using the term loosely, I know) has it that black holes slowly evaporate into radiation - at a net increase in entropy. Newtonian and relativistic physics both support conservation of energy - to the point where relativity actually relies on the conservation of energy to do many of it's transitions in coming up with the theory, although it had to change the definition of energy to make everything work. Historically, every time someone has thought they have come up with a way around either, it has been an issue of a new form of energy, a mistake/contamination somewhere along the line, or a hoax. Those two principals are as proven as anything gets in physics, boundaries or no. I've yet to hear of any credible scientific hypothesis that would truly violate either without referring to God in some form.
