I got to thinking about light speed and came to perhaps a different conclusion than the accepted norm. As something approaches the speed of light, time slows down around it. The limiting factor might not be speed but time. If you exceed the speed of light, would time stop? Would it reverse itself? I doubt the latter but the first may be possible. There is a speed barrier at the speed of light, much like how there was a barrier to the speed of sound for aircraft flight. I don’t know what it will take to exceed it, but I do believe (without solid science to back me) the speed of light can be exceeded. It make take doing a lot of experimentation with time as the barrier due to the changes occurring in and around an object that approaches light speed.
