Dunno why I thought of this, but since I did its been bugging me...

At 1600 I leave Point A travelling faster than light and arrive at point B at 1605. The light from starting point A arrives at point B at 1606.

My question is, what happens to me in that one minute gap at my final destination while I wait for the light from my start point to catch up with me?

I wrote a summary some time ago with a very similar thought as the subject. I imagine that looking back at your starting point, you would see an image of it as it was from a time BEFORE you left it. You might even see yourself headed to where you are now, since the light leaving you hasn't caught up with you yet! It would probably look like you are going to crash into yourself. Wouldn't that be a trip!

I'm not sure what he question is. The impossible thing is the faster than light travel. Once you've done that you've violated causality. Not that much interesting would happen as you wait for the light to reach you once youve returned to subluminal speeds. You can similarly be ahead of light by using a mirror.

Big Bang....what did it expand into? How can a singularity expand into nothing....if there is nothing to expand into in the first place? How fast can light travel into or through nothing....

The Big Bang is an expansion of space, not into it. While people need to embed objects in higher dimensional spaces to conceptualize them, the math works fine with or without a higher-dimensional space in which to expand. Probably not a satisfying answer, but it still is the answer consistent with observation.

Don't we need an entirely new model of physics to do this? Current model only lets you go to C, not beyond it. Inventing a new line of physics means we'd have an entirely different means to calculate how something like this work play out.

Let's theorize tachyons--particles with a minimum velocity of C+1 and unlimited top-end velocity. This would theoretically allow me to travel to any point in space instantaneously.

I think the question is easier to think about if I step away to some place 10 light years away--and then look back to where I came from. I would obviously have changed places, but as mentioned, the light is still coming, so I'd be seeing back into time ten years into events that have already happened.

So let's shrink it down to a minute.

I transfer to place X one minute ahead the time it would take light to get there. Looking back, I'd see myself preparing to transport my self one light-minute away. At the time I break C, I disappear (no longer being observable\instantaneously transporting to "the present" time).

So if I was running, reached C, then broke though the C barrier to C+1, I would disappear from measurable view when I break through C, so while I might see myself running towards where I am standing, the moment I break the C-barrier, I'd no longer be visible.
