But more importantly - will we be able to do that Superman movie trick where we just fly around the sun EXCEEDING the speed of light so we can go back in time?

But more importantly - will we be able to do that Superman movie trick where we just fly around the sun EXCEEDING the speed of light so we can go back in time? Joking mainly. With this much time dilation it would be fascinating to just send out tons of probes in different directions at high speed and constant acceleration - this would massively extend their service life - and potentially also massively extend our knowledge of the universe as well. Of course relatively to the people on Earth it would take a long ass time.
