Security ... think about it!
One of those yet-to-be-unraveled things is the Big Bang, the origin of the Universe itself. Our origin, the final question that we have been trying to answer since we came out of the cave and looked up the night sky. We still don't know exactly what happened, but the observation of the Universe from Earth and space probes have caused some physicists to propose many different models. One of these models says that, during the initial inflation period of the Universe, space-time expanded faster than light. If this turns out to be the case, it would make possible the creation of warp drives.
