I don't know about that. I can't measure it, but I somehow think light travels faster than thought, no matter how impulsive and quick it comes to us. Our reactions to say pain to jerk away, isn't exactly a thought, but even if it were, it's not as fast as light speed. I wonder if our thoughts might slow down even further at the speed of light. I mean, if we're not aging, then our entire life cycle would slow down including eating and thinking and sleeping. Or maybe I'm wrong and everything would go faster along with the travel. It would just seem like less time had passed. Conundrum.
