[Tolsti2]

If you were to get in a space ship and travel near the speed of light and go 4 light years away and back, you’d return to earth and only have aged a few weeks while everyone here aged 4 years.

If you go 100 light years, you might age a year, while everyone on earth aged 100 years. That’s how this stuff works. So in a sense there is ‘time travel’ when it comes to gravitation and velocity.

It doesn’t matter if you believe in it or not, it’s a scientific fact.

Your concept is correct but your math is a bit off. Traveling at near light speed, 4 minutes on your ship's clock might pass but 17 years would've passed on earth.

17 years on your ship's clock would equal 13,000 years back on earth.

So don't do it!
