9. FTL Concepts with these Problems in Mind
Next, we want to ask about how one might try to get around these
problems. Many of you have heard of ideas which get around the light speed
barrier problem. For example, if we can do our traveling in some other,
parallel "space", then we won't be bothered by the light speed barrier in
our own space. However, these ideas have a much harder time getting around
the second problem. In fact, to get around the second problem, we will see
that special provisions will have to be made.
Therefore, the format of this discussion will involve the following.
First, we will look at the various concepts which exist for possibly
allowing FTL travel. I will show how each of them allows one to get around
the light speed barrier problem, and I will explain how (without special
provisions) none of them can bypass the second problem--producing unsolvable
paradoxes. Finally, I will introduce some special provisions (beyond the
basic assumptions made for the FTL concepts) and show how one can imagine
using these provisions in conjunction with some of the FTL concepts to get
around the second problem.
