I'm going with my instinctive answer, which is yes, time travel is possible. I remember thinking about travelling in time before I was even 6 years old, and I hadn't read any books on time travel at that point nor had I seen anything on TV to give me this idea.. I put the idea on the back burner when they dismissed the idea of time travel being possible at school. The teachers would laugh off the idea that we might one day travel faster than the speed of light. But, quietly, I've always thought that one day, time travel would be possible, and may have already been done... I'm not sure of the how yet but, that doesn't mean it's not possible...
