Time Travel

Born of science fiction, thinking about time travel has allowed us to visit possible and lost worlds, and rediscover the past through modern eyes. It also raises big puzzles: If you travelled back in time and killed your grandfather when he was a young man, would you still exist? Would changing the past mean you returned to a different present? What about travelling to the future? Two philosophers and a science fiction writer discuss time travel, and how thinking and writing about it has changed science and philosophy.

5:10 The Universe is expanding faster than the speed of light. The new study confirms previous expansion rate estimates based on Hubble observations, showing an expansion of roughly 45 miles (73 kilometers) per megaparsec. (A megaparsec is a measurement of distance equal to one million parsecs, or 3.26 million light-years.)

To time travel you must travel faster than light 🙂.. see this why nothing gets done. That's what they all say because they all are taught the same way. To dwell on problems but never have the tools to solve them...
Look you don't have to travel then speed of light... Just slower....let it pass you up.... Now here is your problem to solve. How to travel slower than light.. when you are light?
