    I always heard "The exception proves the rule." This makes sense if you use "proves" in a very old-fashioned sense meaning "tests", or if what's important is the existence of the exception. If I run a storefront, and put up a sign saying "Emergency - store closed 1-7 PM today", I'm implying that the store is normally open 1-7 PM on that day.

    Michigan can't interfere with the selling of cars from a California company to someone in Michigan. It doesn't matter what else is going on, that's interstate commerce, and the states can't do anything about it.

    Lawsuits can be an effective way to find out what the law means. In this case, the question is about laws superior to state statutes and whether they mean it's illegal to ban direct sales.

    I pay for a real Internet connection (40 Mb/s currently; if that proves insufficient I'll upgrade). It's pretty reliable, but the DSL I had before that wasn't, and there might be a couple of days without home ISP service. Being able to tether during those days was very convenient.

    The charge for data transit is pure profit for Verizon only if the network infrastructure they spend money on is pure loss. Obviously, Verizon isn't going to take that sort of financial hit without getting something for it, so they're going to have to charge their customers somehow. Verizon has to decide how much bandwidth to build, and the more people use the more Verizon has to supply and pay for.

    So, how does Verizon decide how much to build? Mostly, Verizon will estimate what it needs to supply at peak periods, and build for that. If people use more bandwidth in peak hours, Verizon will have to spend more money on infrastructure, so Verizon's costs are based on how much bandwidth people use during peak hours. If you decide you're going to download a gigabyte of stuff every day during peak hours, Verizon has to build enough bandwidth to handle your gigabyte just because of what you do, and it's reasonable to charge you for that - or, to be specific, charge you per gigabyte.

    It gets more complicated with nonpeak hours, and as it happens if the network is far from being saturated it doesn't cost Verizon much of anything to give you more bandwidth to use. However, if this bandwidth is available with no charge for data transfer, people who like to move a lot of data will do it at the no-charge times, and they'll likely become peak hours.

    The question is how customers are to be billed. If it's a flat rate, then there's no incentive not to download everything on Project Gutenberg at peak times, and Verizon has to raise everybody's rates. It's a classic Tragedy of the Commons. If Verizon charges you for data transfer, that collects more or less what it costs them to service you. It's not necessarily fair to have the same rate for peak vs. non-peak transfers, but it has the advantage of making the billing simpler and more understandable.

    GR recognizes time. It's a dimension that's treated differently from space dimensions in certain ways We know of nothing that says that FTL (which is the same thing as time travel in SR) is impossible. There are reasons to believe it might require some form of matter with a negative mass, and while we have no knowledge of such a thing we know how it would behave if it existed, and there's no actual reason that we know why it's impossible.

    Ways to travel between stars without going faster than light? There are some, but they're all pretty slow.

    A self-sustaining generation ship accelerated to 1% of the speed of light would arrive at the nearest star in a bit over 400 years. This is one way to spread through the galaxy, but you've got to be patient. Variations include some sort of suspended animation or sending genetic material to recreate the species at the other end or just being very long-lived and not easily bored (sufficiently advanced robots may qualify).

    Ways to get up to high speeds include using thermonuclear explosions to provide thrust (the 1960s Project Orion), something like solar sails with assist from the launch systems (makes slowing down at the other end a bit hairy), or having an extremely powerful and compact power source to accelerate reaction mass to ridiculous velocities (matter and anti-matter combining could work).

    If you can go faster than light, there will be inertial reference frames in which you are traveling backward in time. If Special Relativity holds, you can go FTL in different reference frames and achieve time travel.

    Assume two spaceships, each with a properly tuned ansible (instantaneous communicator from LeGuin's science fiction). They pass each other at time T, moving at relative speeds so that the observed time dilation figure is 0.5 (about 88% of the speed of light). This means that, from the point of view of each ship, time is passing half as fast on the other. Both agree on what time T is.

    The guy on Ship A spills his coffee onto himself at T + one hour. He's annoyed by this, so he sends a message to Ship B saying what he did. When does Ship B get it? If it's instantaneous, then A should perceive it being sent at the time of transmission, which is T + one hour. He observes ship B as aging one-half as fast, so from his point of view his T+ one hour is Ship B's T + thirty minutes. The guy on ship B echoes the transmission at T plus thirty minutes. From his point of view, it is T plus fifteen minutes on Ship A, so the guy in Ship A receives a message at T plus fifteen minutes describing what will happen at T plus one hour.

    The above follows from the basic principles of Special Relativity. It is possible to imagine a Universe that doesn't work that way, but in that case Special Relativity does not hold. Very simply, if you have FTL and Special Relativity, you have time travel.

  18. Child porn is defined by what it shows rather than the effects it has on any individual person. Ten-year-olds playing with a slip and slide while wearing minimal swimsuits does not normally count, because neither shows nor hints at sexual activity, and all the important bits are covered.

  19. If the enemy expects an attack at dawn, they'll be ready for it. Then they'll lose alertness and be surprised when you attack an hour and a half later, assuming your preparations won't be spotted in that time. Strategy is odd that way: it's often worthwhile to do things in an inferior but unexpected way. Also, Kursk was in some ways a German victory, although it left the Germans a lot worse off strategically than before. (The Germans smashed roughly half the Soviet mobile forces, at the cost of seriously degrading their own armored forces. This left the Red Army with the only real functioning large mobile forces in the theater.)

    Of course, non-criminals generally don't expect a dawn police raid, so this isn't entirely applicable.
