Let me try this again*. Here's my dilemma with the concept of time travel. I'm fine with the idea of "time" being a long stream that can be entered and exited at different points. The thing I can't wrap my head around is that to go backwards or forwards in time, you'd also need to travel across impossibly vast distances, since the Earth (and our solar system) is constantly moving and therefore would not be in the same physical location as it is right now. My point, lame that it may be, is that we often talk about traveling through time as if location is a constant, but the reality is that it is not.
Now, if I could go back in time, I would, of course, post something completely different.
*Thanks, Houvenagle, for calling me out on this post. In my haste to post something for today, I missed a few steps in my thought process.
