Assuming I got zapped back to the year 318 but stayed in the same physical location, I would be in a world of hurt.
What existed in Central Texas in the year 318?
I suppose I would try to carve images of technology in the limestone and really freak out future archaeologists.
If you stay in the same physical location and consider that the earth is moving through space along with everything else in the universe, you would find yourself in deep space and then explode. 1700 years later the earth would collide with your corpse.
