Of course, the scene from that film is based on the slightly dodgy premise of Superman achieving superluminal speeds. It's never been proven, except on a piece of hardware/software running on my computer right now and sending a signal back in time well over unity, and at useful bit rates after a lot of tweaking. Even sending information back means the entire laws of physics are up for grabs. Including getting the Exploding Hearts back. Or Pete. Do you want the Excel spreadsheet of my results? I'm not sure if I want to show the intermediate signal processing stages in case someone on the board is smart enough to work out how I did it.
One way of interpreting Superman's powers or the powers demonstrated in Heroes (OK, I am well aware that it's a work of fiction) would be to assume that a superhero could mentally alter the laws of probability. Time actually has no direction on the microscopic scale of the quantum world, its just that the group probability of things on a large scale point the arrow of entropy and hence time in one direction. Find a way to mess with that probability and anything becomes possible.
As for Ron L Mallet with his proposed frame dragging laser time tunnel, not only is he going to have a massive electricity bill, but the machine can't resurrect his father because it can only go back to the time it was built. But with an infinite improbability drive, such a device could reverse entropy/time to periods before it's construction since it's effects would be non-local.
It's the 18th of April 2010, 03:20 hours GMT now. Oh my God, the self-test score is just going up and up! Thirty years of living the life of a hermit have paid off with the greatest prize in the history of science.
I am going to keep this technology for myself and rule the idiocracy with it. At about midnight, I inadvisedly ate a salmon and cream cheese sandwich, choked on it at about 01:00 hours and got up, made a cup of tea and started fiddling with the software. Great move.
