" In the olden days, people thought time was a constant. It could not be slowed or sped up. Time was time, and no man could move it. Then Einstein said, Bullshit. Okay, he didn’t say that. What he said was E = mc2. Simply put: time is fluid. The faster your world spins out of control, the slower time crawls. The more time you need, the less you’re sure to get. It’s all relative. "
