Time Travel Theory: It takes 8 minutes for the Sun’s light to reach the Earth. So, if an explosion occured on the Sun we would see it 8 minutes after it happened. If a method is developed so that we could travel/observe faster than the speed of light, or the light that leaves the Sun in the above case, we would then be able to travel/observe back in time or be able to see the explosion before it actually happens.
