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

I find it useful to remind myself that the “speed of light” is a bit of a misnomer. We should use “speed of causality”. We have yet to observe anything happening faster than that speed, denoted *c*. Its just that light is a very common thing that moves at the speed of causality, so we started calling it that, but plenty of other things move at that speed as well (gravity, information, anything with zero mass).
Everything would like to traveling at the speed of causality, but having mass slows us down. That is what mass is.
Next time you are at a cocktail party, find a physicist and get drunk with them. I find that they don’t bs you and pretend to know things. They just admit that we don’t really know why all the rules change at the quantum level. That we don’t know if the universe is made out of discreet smallest units like atoms, or if it is turtles all the way down, or a complete analog soup. We don’t know why light sometimes acts as a particle, and other times like a wave. And….it seems to act differently if we are watching it? WTF?

Future generations of humans will look back on us, and pity our ignorance the same way we look back on the ignorance of ancient peoples.
Are there more than 3 spatial dimensions? Is it possible to harness gravity itself and use it as a propulsion mechanism? WTF is dark matter? What is outside the simulation? Are only living things conscious or can the universe sense itself? Uhhh, what is consciousness anyway?
Tachyons are the least of our curiosities.
