There's some science to all this time travel shit, but you'd be better off asking a fella by the name of Gordon Freeman. He's gotta be the sharpest motherfucker I've ever seen when it comes to all this science shit.

Not any science that I can think of. Hell, it shouldn't even be able to make any sound without being plugged into an amp, but there you go. I could show you something else that might convince you, but it kinda freaks people out.
