Ok honestly.. its is not about transparent metal aluminium. You know that aluminium oxide is the stuff that is used in for example you garden variety fuse, yes? Nothing magic, in fact aluminiun is of the most common substances in the earth.Star Trek Tech Made Real - Transparent Aluminum
I'm one of those who don't believe that time travel as we normally think of it in sci-fi is possible. I understand how mathematical models can make it seem possible, but switching variables around on paper or in a simulation is very different than undoing a physical sequence of events. This gets quite involved, but there's a logic to the impossibility. I just doubt most people have reflected on it long enough to grasp it.Well, I suppose its as much about belief as anything.
Like time travel. Is is possible or not? Many physics theories do not forbid it.
Myself, I prefer the multiverse theories. That means that you cannot kill your grandfather - in some realities you did that and in some you did not.
What this means is that there is no time-travel causality... I'd suggest you to read David Deutch: The Fabric of Reality. I'm on same lines with him on these matters..
