So you're interested in time travel. Think you can just strap a flux capacitor to your back, get struck by lightning, and become a knight of King Arthur's court before suppertime? Think again.
Time travel is no simple endeavor. Just because you have plutonium, a sweet car from the 1980s and the blessing of your local mad scientist doesn't mean you're ready for what awaits you on the other side of a wormhole (like hungry dinosaurs and probe-happy aliens). Time travel is 98 percent preparation, 1 percent luck, and around 53 percent screaming and running like a scared child*.
So before you go flinging yourself into the waiting jaws of grizzly molecular-decomposition death, consider the following safety tips, a small sampling of what's on offer in the thing you really need to survive your adventures in trans-temporal relocation: So You Created a Wormhole: The Time Traveler's Guide to Time Travel [Berkley Books, $14.99]**. These tips constitute a few of the most important things you should be thinking about before and during your various time travel endeavors, and may well save your life (but probably not), as well as the lives of all the hapless billions you endanger with your wanton disregard for the laws of physics (but probably not).
