Well, that's exactly what the experiment that this thread was started about is setting out to answer. If the switch can send a signal to the microwave to start seven minutes ago, then the dinner will be cooked by the time the switch is thrown. (Unless it's one of those big Marie Callendar's dinners that take 8-10 minutes, in which case it will be cooked but still cold in the middle. I hate that.)
Dan, I honestly know pretty much nothing about your credentials except to say that they are almost certainly more extensive than mine. However, unless I've missed something, John Cramer of the University of Washington - who is the one apparently in charge of performing the experiment - is more up on this stuff than ANY of us on this board. If he and his team are thinking that this might be possible, then I have a hard time understanding where you find the wherewithal to dismiss it out of hand without experimental evidence of your own.
