I can't remember exactly how much would it take him time to travel with the speed of light to skip a generation or two. Traveling to the past is impossible from what I heard, maybe it's possible but without interaction and other obstacles that wouldn't really make it really a travel to the past.
Yes, this is the theory I know and believe in. I confused this with Einstein when ramsej brought it up.

The process with the speed of light is actually quite easy to understand. Imagine you are looking directly at the Big Ben and the time is showing 2pm. You reverse at the speed of light with an infinitely-capable telescope so you keep seeing the time on the clock. By travelling at the speed of light, the light waves that left at 2pm keep travelling in your direction at the same speed. So if you keep this up, you will see the Big Ben clock permanently showing 2pm and everything constant.
If however you increase the speed further (i.e. faster than the speed of light), then you will suddenly start seeing the waves that left the Big Ben at 1:59pm, then at 1:58pm etc. The clock starts moving backwards. So you start seeing waves that left in the past. However, it doesn't mean that you stop ageing. That is, if you spend a year travelling this way and then make a U-turn and travel back to Earth you will still have aged by the 2 years that you spent travelling. Upon arrival, everyone would also have aged by the same 2 years.

Parallel universes and alternate timelines. Any topic for quantum physics are all interesting and mind boggling.
