ONE MODE of TIME TRAVEL

Time travel to the FUTURE is indeed possible, according to Einstein's theory of Relativity...

Leave Earth at the speed of light, hang out for a few DAYS on an Alien World, return to Earth at the same speed that you left it....

And you will find, depending on the distances involved, that 100 years or so on Earth have passed in what for you was only a week!

You have traveled to the future, the easy, most possible way....
