Okay, well I have in my thoughts anyway! Here I am bored out of my mind tonight watching TV when they mentioned the speed of light. Nothing can go faster than the speed of light. But, why? (and no, the answer to my "why" question is not because Einstien said so...). Theoretically, in my wandering thoughts, I dont see why a speed higher than that of the speed of light is impossible. For example my thought goes as such: Its the year 3000! Yay. Were in a spaceship traveling at precisely 670,616,640 MPH, or 186,282.4 miles per second, which is also the speed of light! Not too shabby, and a tad faster than your mother's Toyotal Prius, and certainly beats walking. Anyway, traveling at the speed of light in the year 3,000 is nothing spectacular. Of course it seems strange in the present year of 2010, but just imagine what someone 1,000 years ago would have thought about cellular phones, electricity, and jet aircrafts! Back on track. We're traveling merrily along and I am seated in the back of the ship. I get up and walk to the front of the ship at a pace of exactly 3 MPH. Now, in a fixed point relative to the outside of the ship my mass would be traveling in a linear direction at 670,616,643 MPH, uh oh, thats faster than the speed of light! Is this possible? According to the "laws" of physics this is not possible. If I am on-board this spaceship traveling at the speed of light is it impossible to move anywhere in the forward direction because if would exceed the speed of light, the speed at which nothing can exceed in all the known Universe? I will say I am definatly not a physics expert nor aficionado. Just a regular guy out there with a thought in my mind keeping me up tonight. I would love to hear some input on my theory here to help me better understand! My spaceship metaphor can be replaced with numerous other metaphor's if you will, but the originally question remains, is it absolutely 100% impossible to EVER exceed the speed of light?
