I’m wondering if interstellar travel is possible. So I guess the starting point is figuring out FTL travel.

Faster than light travel is NOT impossible thanks to time dilation. What’s impossible is for observers to see you moving faster than light.
For example if you moved exactly the speed of light and traveled to a star that is 100 light years away and back the trip for you would be INSTANT, because at the speed of light the time stops completely!
But when you get back to Earth you find that while for you were away just a second 200 years passed on Earth.
This also means that time machines are only half impossible. You can go forward, but can’t go back.
edit: There is still one “small” problem of actually surviving the acceleration, needing infinite energy and having infinite mass while traveling at the speed of light.
