Let me rephrase it for the pedantic. I can imagine FTL travel, but can we do it with existing technology? No. Could we do it in the future: it’s possible. Someone may develop a way of folding space, or we may figure out propulsion that gets up to 0.9x, who knows. That’s the part I’m getting at.
Just like now, there were people back then that said “without a doubt, that will not be possible”. Human understanding is constantly shifting and growing.
It’s not pedantic to point out that people in the 1920s absolutely thought about leaving the planet. I understood your point, as I said it irritates me when people act like people in the past had no clue what was coming or were too stupid to think of things like space or air travel. Leonardo da Vinci was designing “flying machines“ in the fourteen-fucking-hundreds. People were thinking about this shit.
FTL is almost certainly impossible because the laws of physics limits the speed of information to the speed of light, which is why we can't use quantum entanglement to communicate information. So the only way I can see it happening is with wormholes, but we've never proven that they can actually exist in a stable form.
We can still get close to the speed of light but the consequences for those doing so are pretty severe. If you wanted to go farther than the nearest stars, everyone you know would die from old age by the time you got back.
We have also not found a way of merging quantum physics with regular physics models so there is still a possibility al be it slim
