Is it scientifically possible to time travel? I am interested in this phenoneme, not to visit the history or the future, but I want to visit other solar systems and galaxies. I want to know how life would be on other planets. I depart from the hypothese that the universe is large enough to have uncountble numbers of planets where just like the Earth intelligent life forms have evolved. I know that nothing can go faster then c, but as far as I know there is no phisical law that says it is impossible to make the time go faster or slower. Even more I think it is also possible to move the space where a spacecraft is flying in. What do you think about this idea?
