yeah I agree the movie is a great idea if it was just a replay of a simulation.
Which is very much possible and is completely based in reality, everyone knows when we see the light off a distant star we are seeing its existence millions years ago, not the way the star is now.
So I always wondered, me sitting at this computer, the light that is bounced off, if it was able to shoot into space it too would be lagged by millions of years.
And here is where it gets interesting we all know we don't just reflect light. Our bodies Emmit all types of energy, we are even slightly radioactive, there are probably forms of energy produce off our body science haven't even discovered (I just read scientist found a band new substance in a meteor)
So if scientist can record this AFTER GLOW, this new energy off everyone, this new energy which travels slower than light, and keep playing it in a simulator. This can actually really happen.
For instance if we measure light, isn't the light from 9/11 just now detected in some far off distance in space?
Its all just a matter of detection of different types of energy. And the Speed in which it travels.
Simplest example is Lighting, we can see a the light coming from 4 miles away pretty much instantaneously since light travels so fast, but we don't detect the sound until almost 4 seconds later? So did we travel back in time and something thats 4 seconds old? of course not.
Same thing with Source Code, maybe there are new forms of energy and detection we haven't yet invented/discovered, what if there are energies that does travel faster than light, FTL travel? What if there are energies that travel much much slower than sound? Like an After Glow?
Very interesting concepts thats really not that complicated and almost not science fiction but very much based in reality.
